EN 143 and related standards
• EN 143 describes test method and classification for respirator filters
• All categories of respirators have different standards but they all refer to EN 143 for test method– Filtering face-pieces (disposable masks) (EN 149)– Re-usable half masks (EN 405 or EN 140, filters: EN 141, EN 143,
EN 371, EN 372)– Re-usable full face masks (EN 136)– SCBA self contained breathing apparatus (EN 137 or EN 145)
• Certification and QC testing is not described in the test method– They are described in EU PPE guidelines

European PPE Guidelines
• These Guidelines apply to all personal protection equipment (safety shoes, rock climbing gear, respirators…..)
• All respirator filters, filtering face pieces etc fall under categories II or III
• EC type-examination is done by accredited labs – BGIA in Germany or HSL in UK are
examples.• Category III filter products require “CE
nnnn” certificate– nnnn stands for EN143, EN149 etc.– P2 and P3 filters and FFP3 face masks
typically are category III– QC system or production QM is
necessary– Production QM can be done by the
manufacturer (regular audit necessary) or statistically by an accredited lab

EN 143 and related standards: filter classes
• EN 143: Three filter classes for respirator filters:
Filtering face-pieces are also classified according to their protection factors: FFP1, FFP2 and FFP3 with of 4, 10 and 30, respectively.

Testing Respirator FiltersUS 42 CFR part 84
• Certification Testing (NIOSH) requires filter loading tests that vary in length from a few minutes to ~ 2 ½ hours each (Destructive Test)
• Quality Control Plan (part of certification process) specifies quality control testing that will be done (after respirator is approved for manufacture)– QC testing can be short (10-12 second) tests of initial
efficiency– Large number of filters (in some cases 100%) will be tested– Some level of loading test may also be included (annual or
testing each lot of media are examples)– Most testers are used for QC testing

Testing Respirator Filters
• Respirator Filters– NIOSH uses TSI 8130 for their Respirator Standard
(in accordance with 42 CFR part 84)• Manufacturers worldwide make respirators for US market
(must comply with 42 CFR part 84)• Many respirator manufactures want to copy EXACTLY
what NIOSH does for testing.
– Most of the Model 8130 filter testers so far used in the field (>70% historically) are for testing respirators or media used for respirators.

New EN 143 Equivalent Testers• TSI Automated Filter Testers
models 8127-1-EN (paraffin oil only) and 8130-1-EN (paraffin oil and NaCl) are now available.
• Oil and salt aerosol generators for EN equivalent testing are also available to upgrade existing testers.
• It is now possible to do testing according to European and USA standards, with both oil and salt, all in one machine.

What’s Different about the EN Testers Compared to the
Current Testers?• Essentially, the –EN aerosol generators are
different– Both the oil and salt aerosol generators have been
specially adapted (i.e. set-up and operating parameters) and fully checked out to new procedures
– EN 143 and US versions will also have different check out certificates, EN 143 compliant generators well be specially labeled

The ‘Equivalence Dilemma’
• It is a well known fact that the particle size distribution of a well calibrated EN 143 system is different from the size distribution described in the standard (original measurements have been made more than 20 years ago).
• Mass concentrations must be adjusted for both oil and salt aerosol
• Aerosol substance (oil test) and size distribution (oil and salt test) must be adjusted
– Paraffin oil: Aerosol should match EN 143 size distribution as measured at BGIA. Test results must match!
– NaCl: Aerosol size distribution must be adjusted such that the light scattering photometer response is equal to the response of a sodium flame photometer (as measured at BGIA). Test results must match!
• An extensive series of comparison measurements was run last November at the German PPE accredited test lab BGIA, Sankt Augustin

Positioning Statement
• For manufacturers of respirators, respirator filters, half masks (i.e. disposables), etc. who must adhere to EN 143, the TSI automated filter tester models 8130-EN and 8127-EN provide equivalent QC-measurements for both oil and salt test aerosols.
• Compared to competitive filter testers, the TSI model 8130-EN offers both oil and salt testing in the same machine. Additionally, this same tester can be easily converted and used to comply with US 42 CFR part 84 by purchasing and installing only the appropriate aerosol generators.
• As a result, customers will greatly benefit by realizing a significant reduction in capital investment, space requirements, operating costs, and operator training requirements.

SFP SERVICES (Sodium Flame Photometry)
SFP SERVICES is the product of two people JIM WILLS and DENNIS FIVEASH. http://www.sfpservices.com
Moore's (Wallisdown) Ltd. (manufacturer of sodium flame test equipment up to 1998) decided to concentrate their efforts on their core business (aerospace components) and close the air filter test equipment division. With over 30 years experience of sodium flame test equipment and testing between them Dennis and Jim decided to set up SFP SERVICES to continue the supply and service to old (ex Moores ) and new customers in every way they could.
SFP also distributes Grimmequipment for filter testingin the UK, serving-EN 1822 (HEPA/ULPA)-ASHRAE 52.2 (Grimm OPC)-EN 779 (Grimm OPC)

Palas® GMBHFilter Test Systems for EN standard
Palas has developed a Salt tester using a SFP Sodium flame photometer and using their own components for aerosol generation, filter holders etc.
For Oil testing they use OPCs (Welas) as detectors and claim they perform a “better” test than EN 143. Customers hardly agree since they need to comply with the standard.

Summary of ATI Competitor Review
* Recommended (not required) for determining particle size distribution
© 2008, TSI Incorporated
40
TSI Confidential
Comparison – Aerosol Generation
• ATI Laskin Nozzle generator– Sensitive to temperature and
exhaust backpressure• Affects concentration and
particle size
– Narrow range of liquid levels to keep consistent particle size
– They used impactor technique for their oil generator
– Charge $1400 for kit to convert from DOP to PAO
• TSI uses an atomizer– Insensitive to temperature and
pressure– Can operate over large range
of liquid levels– Use felt filter to stable aerosol
size– Can generate DOP and PAO
without additional cost
© 2008, TSI Incorporated
41
TSI Confidential
Comparison – Detector• ATI uses Single Photometer
– Calibrate at the beginning of shift • Measure background (zero) and
upstream concentration (span) • Rely on these values for all penetration
calculations until they calibrate again
– Manual recalibration required 3-4 times per shift
• To measure background and upstream concentration
• Each recalibration requires 3 to 10 repeats (3-5 minutes per repeat)
– Only measuring Downstream concentration during filter test
– Full flow goes through photometer• Takes a long time to purge aerosol
after failed filter• Increases false negatives for next
2-3 filters
• TSI uses Dual Photometers– Calibrate at the beginning of shift
• Measure background (zero) and upstream/downstream concentration (span and correlation)
• Measure background and upstream and downstream in every test
– Automated calibration is done during every test
• Automated Zero and Span• This doesn’t increase test times• Most accurate penetration values
– Simultaneous upstream/downstream concentration measurements
– Partial sample flow during test• Purge design to clear photometers
between tests– New Background every test

Comparison – Utilities
• ATI Air consumption– 12 SCFM
• Laskin Nozzle requires more air than atomizer
• Use Venturi pump to create flow
• Requires larger investment in compressors and lines
• ATI Exhaust– Needs to be balanced to
atmospheric pressure• If not, particle size is affected
• TSI Air Consumption– 7 SCFM
• Atomizer requires less air than Laskin Nozzle
• Internal Vacuum pump consumes no air
• TSI Exhaust– No requirement to
balance

43
TSI Confidential
Comparison – Flow Measurement
• ATI Mass Flow Meter – Measure mass flow
• Mass flow does not relate to face velocity
– Requires frequent manual entries of temperature and pressure to correct the flow
• TSI Orifice Flow Meter– Measure Volumetric Flow
• Volumetric flow is directly related to face velocity
– No need to compensate for temperature or pressure

Customer Perceptions
• ATI is more rugged– Industrial look and feel
• ATI is more accurate– Based on having more digits on display
• ATI designed for Automation– TSI testers also used in automated systems
• TSI tester is for research market– We engineered for manufacturing
• Speed• Automation of purging, zeroing, etc.
