Notice and Disclaimer of Liability Concerning the Use of IEEE Documents: IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While IEEE administers the process and establishes rules to promote fairness in the consensus development process, IEEE does not independently evaluate, test, or verify the accuracy of any of the information or the soundness of any judgments contained in its standards.

Use of an IEEE Standard is wholly voluntary. IEEE disclaims liability for any personal injury, property or other damage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance upon any IEEE Standard document.

IEEE does not warrant or represent the accuracy or content of the material contained in its standards, and expressly disclaims any express or implied warranty, including any implied warranty of merchantability or fitness for a specific purpose, or that the use of the material contained in its standards is free from patent infringement. IEEE Standards documents are supplied "AS IS."

The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE standard is subjected to review at least every ten years. When a document is more than ten years old and has not undergone a revision process, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE standard.

In publishing and making its standards available, IEEE is not suggesting or rendering professional or other services for, or on behalf of, any person or entity. Nor is IEEE undertaking to perform any duty owed by any other person or entity to another. Any person utilizing any IEEE Standards document, should rely upon his or her own independent judgment in the exercise of reasonable care in any given circumstances or, as appropriate, seek the advice of a competent professional in determining the appropriateness of a given IEEE standard.

Translations: The IEEE consensus development process involves the review of documents in English only. In the event that an IEEE standard is translated, only the English version published by IEEE should be considered the approved IEEE standard.

Official Statements: A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual shall not be considered the official position of IEEE or any of its committees and shall not be considered to be, nor be relied upon as, a formal position of IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be considered the personal views of that individual rather than the formal position of IEEE.

Comments on Standards: Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important to ensure that any responses to comments and questions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions except in those cases where the matter has previously been addressed. Any person who would like to participate in evaluating comments or revisions to an IEEE standard is welcome to join the relevant IEEE working group at http://standards.ieee.org/develop/wg/.

All staples shall be of sufficient strength and rigidity to resist bending and distortion beyond the point of usability when installed by normal driving methods under normal conditions.

9.4 Protective coatings

9.4.1 Ferrous staples

All ferrous staples shall be hot-dip or electro-galvanized. The points of cut or slash point staples need not be galvanized

9.4.1.1 Hot-dip galvanizing

Hot-dip galvanizing shall be in accordance with ASTM A153/A153M for class D hardware, the minimum thickness on significant surfaces to be 0.001445 in (0.85 oz/ft2).

9.4.1.2 Electro-galvanizing

9.4.2 Copper-coated staples

Copper-coated staples shall consist of a steel wire core with a copper coating thoroughly bonded thereto so that the interlocking crystalline union is secured between the two metals. The copper thickness at any point on the wire before forming into staples shall be not less than 6% of the wire radius. The steel core wire shall be of a grade and quality suitable to meet the requirements of this standard.

9.4.3 Aluminum-clad staples

Aluminum-clad staples shall consist of a steel wire core with an aluminum coating permanently and integrally bonded thereto. The aluminum thickness at any point on the wire before forming into staples shall not be less than 10% of the wire radius. The steel core wire shall be of a grade and quality suitable to meet the requirements of this standard.

10. Finish

All bolts, nuts, screws, washers, and staples covered in this standard shall be free from burrs, seams, laps, and irregular surfaces that affect serviceability.




32

11. Marking

All bolt heads, eyebolt shanks, nuts, washers, and lag screw heads shall bear the manufacturers symbol or identification mark. Each shipping package of fasteners covered in this standard shall be marked with the vendor's name and catalog number.

12. Definitions for acceptability and sampling

acceptance quality level (aql): The maximum percent defective (maximum number of defects per 100 units) that, for the purpose of a sampling inspection, can be considered satisfactory as a process average.

average test value ( nX ):

nX = (X1 + X2 + X3 + ... + Xn)/n

where

X1, X2, ..., Xn, are individual test values and n is the total number of units tested.

defect: Any nonconformance with specified requirements of the tested unit of product. For purposes of this standard, a defect is defined as a unit of product that, when tested, falls below its specified rated ultimate strength.

lot: A quantity of line fasteners selected and agreed upon by the manufacturer and customer as being representative of a homogeneous population. Each lot, as far as is practicable, shall consist of units of product of a single type, grade, class, size, and composition that are manufactured at essentially the same time and under essentially the same conditions. Consideration should be given to limit the lot size, where applicable, to each heat-treating and/or annealing process of a group of units. As necessary, the manufacturer shall provide adequate and suitable storage space for each lot and means for proper identification. Any lot shall not exceed 35 000 units.

major defect: A unit of product that, when tested, falls below 85% of its specified rated ultimate strength.

sample: One or more units of product drawn from a lot, the units of sample being selected at random without regard to their quality.

sample size: Based on the lot size. Minimum sample sizes are given in Table 17.

Table 17 Minimum sample size

Lot size Sample size 1 to 15 2

16 to 50 3 51 to 150 5 151 to 500 8

501 to 3 200 13 3 201 to 35 000 20




33

13. Requirements

The inspection criteria used in this standard correspond to sample size code S-3 with a double sampling plan for normal inspection having an aql of 2.5% (see ANSI/ASQC-1993).

14. Determination of acceptability

The acceptability of a lot shall be determined by the use of Table 18.

Table 18 Acceptance/rejection criteria

Test sample Sample size Cumulative sample size Accept Reject Single 2 0 1 Single 3 0 1 Single 5 0 1 First 8 8 0 2

Second 8 16 1 2 First 13 13 0 2

Second 13 26 1 2 First 20 20 1 3

Second 20 40 3 4

The lot shall be considered acceptable when the number of defects found in the first (or single) sample is equal to or less than the first acceptance number from Table 18. If this acceptance criterion is met on the first sampling, a second sampling is not needed. If the number of defects found in the first or single sample is equal to or greater than the first rejection number, the lot shall be rejected without a second sampling being allowed. If the number of defects found in the first sample is between the first acceptance and rejection numbers, a second sampling of the size given in Table 17 shall be tested. The number of defects found in the first and second samples shall be accumulated. If the cumulative number of defects is equal to or less than the second acceptance number, the lot shall be considered acceptable. If the cumulative number of defects is equal to or greater than the second rejection number, the lot shall be rejected.

Both the manufacturer and the end user shall reserve the right to reject the entire lot if a tested unit of product is found to have a major defect (i.e., falls below 85% rated ultimate strength).
