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
19、properly designed 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 min
20、imum break-ing requirements 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 a
21、dditionaltest specimens from the same lot may be tested. If bothadditional specimens conform to the minimum breaking forcerequirements, the chain will be considered acceptable.TABLE 1 Single Loop Chain (Class SL)Trade Size Material Size,in. mmNominal InsideLength (P)in. mmApproximateWeight per100 ft
