Oversized material may be used for

20、all applications.8. Finish8.1 The manufacturer may apply a surface treatment orfinish of their own choice for identification or corrosionresistance unless the customer specifies otherwise. The surfacetreatment or finish shall not alter the chain in a manner thatwould cause the chain to not meet the

21、other provisions of thisstandard.9. Mechanical Requirements9.1 Proof TestAll chain shall be tested to at least the proofload prescribed in Tables 1-3 for the appropriate grade and sizechain. When so tested it shall withstand these loads withoutloss of chain integrity. Links or chain segments that do

22、 notwithstand the proof test load shall be removed from the chain.9.2 Breaking ForceThe breaking force test specimen shallconsist of a length from the lot containing at least the numberof links in Table 4. All chain that is heat treated shall be in thequenched and tempered condition before the break

23、ing force ismeasured.9.2.1 Fixtures for securing chain in a testing machine shallbe properly designed to support securely the shoulder of thelink (see Note 2). The opening in the fixture shall not be morethan 125 % of the stock diameter being tested. Links engagedin the testing fixture shall not be

24、considered part of the testspecimen.NOTE 2“U” bolts of the same or larger diameter and the same orgreater strength may be used to secure the chain to the jaws of the testingmachine.9.2.2 Test specimens shall meet or exceed the minimumbreaking force values given in Tables 1-3 for the appropriategrade

25、 and size chain.9.3 Elongation:9.3.1 All chain which is heat treated (see 6.2) must be in thequenched and tempered condition before the elongation ismeasured.9.3.2 The elongation test specimen shall consist of a lengthfrom the lot containing at least the number of links in Table 4.9.3.3 A positive l

26、oad not exceeding 10 % of the proof testshall be applied for determining the original gage length(L0).9.3.4 The elongation shall be based on the total extension atfracture. This is expressed as a percentage of the change inlength (DL) divided by the original gage length (L0). Theelongation may be de

27、termined by the equation below or byautographic recorder or side scale.Elongation %! 5 $DL/L$0% % 3 100where:DL = test specimen final length at fracture test speci-men original gage length (L0), andL0 = original gage length (sum or the inside lengths ofthe test chain links, not counting the fixture
