1、Designation: A466/A466M 07 (Reapproved 2012)Standard Specification forWeldless Chain1This standard is issued under the fixed designation A466/A466M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A numbe

2、r in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers weldless chain suitable forappli

3、cations where a light and flexible chain is required. Thematerial may be steel, brass, or bronze.1.2 Seven classes of chain are covered:1.2.1 Class SLSingle-loop chain.1.2.2 Class DLDouble-loop chain.1.2.3 Class SHSash chain.1.2.4 Class SFPlumbers chain.1.2.5 Class SJSingle-jack chain.1.2.6 Class DJ

7、force inpounds or newtons at which the chain, during manufacture, hasbeen found by representative testing to break when a constantlyincreasing force is applied in direct tension.3.1.1.1 DiscussionThis test is a manufacturers attributeacceptance test and shall not be used as criteria for service.3.1.

8、2 lot, nfor the purpose of acceptance testing, a lot shallconsist of 3000 ft 1000 m or fraction, thereof, of the samegrade and size chain. If a continuous length of chain exceeds3000 ft, it shall also be considered a lot.3.1.3 working load limit (WLL), nmaximum combinedstatic and dynamic load in pou

Ordering Information4.1 It shall be the responsibility of the purchaser to specifyall requirements that are necessary for material ordered underthis specification. Such requirements to be considered in

10、clude,but are not limited to, the following:4.1.1 Product to conform to Specification A466/A466M andyear of issue,4.1.2 Class of chain,4.1.3 Material size or trade size of chain,4.1.4 Material of chain (steel, brass, or bronze),4.1.5 Quantity of chain in feet metres,4.1.6 Length of each piece, if re

11、quired,4.1.7 Finish, if required,4.1.8 Certification of test(s), if required, and4.1.9 Acceptance of inspection by purchaser, if required.5. Materials and Manufacture5.1 The selection of the base material is left to the judgmentof the individual chain manufacturer provided that the chaincomplies wit

12、h the requirements contained within this specifi-cation.5.2 The methods utilized to produce the chain are left to thejudgment of the individual chain manufacturer provided thechain complies with the requirements contained within thisspecification.1This specification is under the jurisdiction of ASTM

United States16. Dimensional Requirements6.1 The chain shall conform to the dimensional require-ments a

16、s specified in Tables 1-7. The tolerance is 67 % fromthe specified nominal dimensions for all chain classes exceptClass SF. Class SF has a maximum length criterion. The insidelength dimension can be measured either by individual link orby measuring the span of 100 links and dividing by 100.6.2 Mater

17、ial Diameter/ThicknessThe diameter or thick-ness of the material from which the chain is manufactured shallbe at least the dimension shown in Tables 1-7, subject to thenormal commercial tolerances listed in Specifications A29/A29M, A366/A366M, A569/A569M, and B248. Oversizedmaterial may be used for

18、all applications.7. Finish7.1 The manufacturers may apply a surface treatment orfinish of their own choice for identification or corrosionresistance unless otherwise specified by the customer in thepurchase order. The surface treatment or finish shall not alterthe chain in a manner that would cause

19、the chain to not meetthe other provisions of this standard.8. Mechanical Requirements8.1 Breaking Force Test:8.1.1 The breaking force test specimen shall consist of alength not less than 1 ft 0.3 m from the lot of chain.8.1.2 Fixtures for securing chain in a testing machine shallbe properly designed

20、 to securely support the shoulder of thelink. The opening in the fixture shall be not more than 25 %larger than the material diameter of the chain being tested.Links in the testing fixture shall not be considered part of thetest specimen.8.1.3 Test specimens shall conform to the minimum break-ing re

21、quirements as prescribed in Tables 1-7 for their respec-tive sizes and classes.8.1.4 Number of TestsThe manufacturer shall perform atleast one test per lot of chain.9. Retests9.1 If the original test specimen fails to conform to theminimum breaking force requirements of 6.1.4, two additionaltest spe

22、cimens from the same lot may be tested. If bothadditional specimens conform to the minimum breaking forcerequirements, the chain will be considered acceptable.10. Rework and Retreatment10.1 Materials that fail to comply to the requirements fordimensions and mechanical tests may be resubmitted afterb

23、eing reworked.11. Inspection11.1 Prior to testing and inspection at the manufacturersplant, the chain shall be free of paint or other coatings whichwould tend to conceal defects.11.2 The manufacturer shall afford the purchasers inspectorall reasonable facilities necessary to satisfy him that themate

24、rial is being produced and furnished in accordance withthis specification. Mill inspection by the purchaser shall notinterfere unnecessarily with the manufacturers operations. Alltests and inspections shall be made at the place of manufacture,unless otherwise agreed.11.3 The purchaser may make tests

25、 to govern the acceptanceor rejection of the material at his own laboratory or elsewhere.The tests shall be made at the expense of the purchaser.12. Rejection and Rehearing12.1 Unless otherwise specified, any rejection based on testsmade in accordance with 11.3 shall be reported to the manu-facturer

26、 within five working days from the date of testing bythe purchaser.12.2 Chains tested in accordance with 11.3 that representrejected material shall be preserved for two weeks from thedate of the test report. In case of dissatisfaction with the resultsof the tests, the manufacturer may make claim for

27、 a rehearingwithin that time.13. Certification and Reports13.1 A manufacturers certification that the chain conformsto Specification A466/A466Mof the date of issue specifiedshall be furnished when requested on the purchase order orcontract.TABLE 1 Single Loop Chain (Class SL)Trade Size Material Size
