Test samples may be taken from rods,bars, or finished chain. Samples for analysis shall
17、 be so takenas to represent the full cross section of the specimen.5.3 Test Methods, Practices, and Terminology A 751 shallbe used for referee purposes.6. Manufacture6.1 Welding ProcessCarbon steel chain may be made bythe forge welding, electric welding, or gas welding process.6.2 Heat TreatmentGrad
18、es 30 and 43 do not require heattreatment, but may be heat treated at the manufacturersdiscretion. Grade 70, after welding, shall be heat treated. Heattreatment shall include quenching and tempering as describedin Terminology A 941.7. Dimensional Requirements7.1 The chain shall conform to the dimens
19、ional require-ments specified in Tables 1-3 for the appropriate grade and sizechain.7.2 DiameterThe diameter of the material from which thechain is manufactured shall not be smaller than the materialdiameter listed in Tables 1-3 within the following tolerance:7 %. 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
28、links, oras determined in 9.3.3).9.3.5 The elongation shall be a minimum of 15 %.TABLE 1 Grade 30 Proof Coil ChainNominal ChainSizeMaterialDiameterWorking LoadLimit, maxProof Test,AminMinimum BreakingForceAInside Length,maxInside Width,minin. mm in. mm lb kg lb kN lb kN in. mm in. mm18 4.0 0.156 4.0
