1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity

3 The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at its
fixed location Example Outside MicrometerF would mean that the laboratory performs this calibration at its
fixed location
4 The presence of a superscript O means that the laboratory performs calibration of the indicated parameter onsite
at customer locations Example Outside MicrometerO would mean that the laboratory performs this calibration
onsite at the customerrsquos location
5 The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter both
at its fixed location and onsite at customer locations Example Outside MicrometerFO would mean that the
laboratory performs this calibration at its fixed location and onsite at customer locations
6 Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations This is due
to the effects of transportation of the standards and equipment and upon environmental conditions at the
customer site which are typically not controlled as closely as at the laboratories fixed location
7 The term L represents length in inches or millimeters as appropriate to the uncertainty statement

1 The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing a
more or less routine calibration of a nearly ideal device under nearly ideal conditions It is typically expressed at
a confidence level of 95 using a coverage factor k (usually equal to 2) The actual measurement uncertainty
associated with a specific calibration performed by the laboratory will typically be larger than the CMC for the
same calibration since capability and performance of the device being calibrated and the conditions related to the
calibration may reasonably be expected to deviate from ideal to some degree
2 The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration The
low end of this range must be an attainable value for which the laboratory has or has access to the standard
referenced Verification of an indicated value of zero in the absence of a standard is common practice in the
procedure for many calibrations but by its definition it does not constitute calibration of zero capacity
