5、ting, load-rated line hardwareIEEE Standards documents are developed within the IEEE Societies and the Standards Coordinat-ing Committees of the IEEE Standards Board. Members of the committees serve voluntarily andwithout compensation. They are not necessarily members of the Institute. The standards
6、 developedwithin IEEE represent a consensus of the broad expertise on the subject within the Institute as wellas those activities outside of IEEE that have expressed an interest in participating in the develop-ment of the standard.Use of an IEEE Standard is wholly voluntary. The existence of an IEEE
7、 Standard does not implythat there are no other ways to produce, test, measure, purchase, market, or provide other goods andservices related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at thetime a standard is approved and issued is subject to change brought about through
8、 developments inthe state of the art and comments received from users of the standard. Every IEEE Standard is sub-jected to review at least every five years for revision or reaffirmation. When a document is morethan five years old and has not been reaffirmed, it is reasonable to conclude that its co
9、ntents,although still of some value, do not wholly reflect the present state of the art. Users are cautioned tocheck to determine that they have the latest edition of any IEEE Standard.Comments for revision of IEEE Standards are welcome from any interested party, regardless ofmembership affiliation
10、with IEEE. Suggestions for changes in documents should be in the form of aproposed change of text, together with appropriate supporting comments.Interpretations: Occasionally questions may arise regarding the meaning of portions of standards asthey relate to specific applications. When the need for
11、interpretations is brought to the attention ofIEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards rep-resent a consensus of all concerned interests, it is important to ensure that any interpretation hasalso received the concurrence of a balance of interest
12、s. For this reason, IEEE and the members of itssocieties and Standards Coordinating Committees are not able to provide an instant response tointerpretation requests except in those cases where the matter has previously received formalconsideration.

Overview1.1 ScopeThis standard covers the requirements for mechanically testing load-rated line hardware for use on trans
28、mis-sion and distribution facilities. This standard is intended to cover routine acceptance testing. It is notintended for initial design tests. This standard specifically addresses, but is not limited to, clevis and eye fit-tings, Y-clevis fittings, socket fittings, ball fittings, chain links, shac
29、kles, triangular and rectangular yokeplates, suspension clamps, and strain clamps. This standard may be applied to other line hardware as agreedupon by the manufacturer and the end user.1.2 PurposeAll load-rated line hardware conforming to the requirements of this standard shall, in all respects, me
30、et theacceptance criteria in Clause 5, when tested in accordance with the procedures outlined in Clause 6.1.3 ApplicationThe routine acceptance tests covered by this standard test the “as-manufactured” condition of the product. Itis expected that the user will select suitable safety factors in apply
31、ing these devices, based on experience anda knowledge of the associated codes and materials involved. Assurance of compliance with this standard is amatter to be agreed upon by the purchaser and the supplier.2. ReferencesThis standard shall be used in conjunction with the following publication. When
32、 the following publication issuperseded by an approved revision, the revision shall apply.ANSI/ASQC Z1.4-1993, Sampling Procedures and Tables for Inspection by Attributes.11ANSI publications are available from the Sales Department, American National Standards Institute, 11 West 42nd Street, 13th Flo

Definitions3.1 acceptance quality level (aql): The maximum percent defective (maximum number of defects per 100units) that, for the purpose of a sampling inspection,
34、 can be considered satisfactory as a process average.3.2 average test value ( ):where X1, X2,.,Xn, are individual test values and n is the total number of units tested.3.3 defect:Any nonconformance with specified requirements of the tested unit of product. For purposes ofthis standard, a defect is d
35、efined as a unit of product that, when tested, falls below its specified rated ultimatestrength.3.4 lot:A quantity of line hardware selected and agreed upon by the manufacturer and customer as beingrepresentative of a homogeneous population. Each lot, as far as is practicable, shall consist of units
36、 of prod-uct of a single type, grade, class, size, and composition that are manufactured at essentially the same timeand under essentially the same conditions. Consideration should be given to limit the lot size, where applica-ble, to each heat-treating and/or annealing process of a group of units.
37、As necessary, the manufacturer shallprovide adequate and suitable storage space for each lot and means for proper identification. Any lot shallnot exceed 35 000 units.3.5 major defect:A unit of product that, when tested, falls below 85% of its specified rated ultimatestrength.3.6 sample:One or more
38、units of product drawn from a lot, the units of sample being selected at randomwithout regard to their quality.3.7 sample size:Based on the lot size. Minimum sample sizes are given in Table 1.4. RequirementsThe inspection criteria used in this standard correspond to sample size code S-4 with a doubl
39、e sampling planfor normal inspection having an aql of 2.5% (see ANSI/ASQC-1993).Table 1Minimum sample sizeLot size Sample size129 330150 51511200 13120110 000 2010 00135 000 32XnXnX1X2X3.

40、35. Determination of acceptabilityThe acceptability of a lot shall be determined by the use of Table 2.The lot shall be considered acceptable when the number of defects found in the first (or single) sample isequal to or less than the first acceptance number from Table 2. If this acceptance criterio
41、n is met on the firstsampling, a second sampling is not needed. If the number of defects found in the first or single sample isequal to or greater than the first rejection number, the lot shall be rejected without a second sampling beingallowed. If the number of defects found in the first sample is
42、between the first acceptance and rejection num-bers, a second sampling of the size given in Table 1 shall be tested. The number of defects found in the firstand second samples shall be accumulated. If the cumulative number of defects is equal to or less than thesecond acceptance number, the lot shal
43、l be considered acceptable. If the cumulative number of defects isequal 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 prod-uct is found to have a major defect (i.e.
44、 falls below 85% rated ultimate strength).6. Test procedure and test reportsPulling hardware used in the application of the load shall be dimensional according to Exhibits AD (seeFigures 15). Pins or bolts that are normally furnished with the hardware shall be used during all tests. Thisstandard ap
45、plies to straight-line loading. Lower ultimate strengths may occur if loaded in a manner otherthan shown in this standard.In performing a tensile test, the load shall be started at zero and shall be brought up smoothly in a practicallystepless manner. The load may be increased rapidly to approximate
46、ly 75% of the rated strength of the hard-ware. Load shall then be smoothly applied at a rate of 25% of rated strength per minute, until the point offailure.All tests shall be recorded in a permanent and organized manner, and shall be maintained for a minimum of10 years. Each test write-up shall cont
47、ain the following:a) Date of test.b) Location of test.c) Catalog part number.d) Hardware rating.Table 2Acceptance/rejection criteriaTest sample Sample size Cumulative sample size Accept RejectSingle 3 0 1Single 5 0 1FirstSecond131313260122FirstSecond202020400334FirstSecond323232641445IEEEStd C135.61
