9、in 5.2,the alternative analysis described in 5.3, or the alternativetension test described in 5.4.5.2 Heat or Cast AnalysisAn analysis of each heat or castshall be made by the manufacturer of the steel to determine thepercentage of the elements specified in Table 1. The analysisshall be made from a

10、test sample taken preferably during thepouring of the heat or cast. The chemical composition thusdetermined shall conform to the requirements of Table 1. Allelements listed in Table 1 shall be reported in the test analysisto the purchaser when requested.5.3 Alternative AnalysisWhen the heat or cast

17、purchaser from a sample taken from a finished spike represent-ing each heat or cast, or 10-ton (9-tonne) lot if spikes arefurnished in accordance with 5.3. The chemical compositionthus determined shall conform to the requirements in Table 1and Table 2.6. Bend Requirements6.1 Body BendThe body of a f

18、ull-size finished spike shallwithstand the bend test described in Table 4 without crackingon the outside of the bent portion.6.2 Head BendThe head of a full-size finished spike shallwithstand the bend test described in Table 4 without showingevidence of forging laps.6.3 Number of TestsOne bend test

19、of each type specifiedin 6.1 and 6.2 shall be made from each 5-ton (4.5-tonne) lot offinished spikes or fraction thereof.7. Dimensions and Permissible Variations7.1 The finished spikes shall conform to the dimensionsspecified by the purchaser, subject to the permissible variationsprescribed in Table

20、 5.8. Workmanship, Finish, and Appearance8.1 The finished spikes shall be straight, with well-formedheads and sharp points and shall be free of injurious and otherimperfections not consistent with good commercial practice.9. Retests9.1 If, during the tension or bend tests, a previously undis-covered

21、 material or manufacturing flaw should be disclosedthat interferes with the test or the interpretation of results, thesubstitution of another sample spike shall be permitted after itis demonstrated to the satisfaction of the purchaser or hisrepresentative, that the condition is not typical of the re

22、mainderof the lot.9.2 Spikes represented by tests that fail to meet the require-ments prescribed in 5.4, 6.1, and 6.2 may be treated andresubmitted for test.9.3 If any test specimen fails because of mechanical reasonssuch as failure of testing equipment or improper specimenpreparation, it may be dis

The maximum copper content shall be deter-mined upon mutual agreement between the purchaser a

38、nd themanufacturer.S2Since spikes are hammer-struck, a minimum Charpy V-notchimpact requirement is desirable, particularly in cold weather. Anew supplement for impact toughness is therefore provided.S3The Charpy V-notch average toughness of three individualtest values, where each bar specimen is tak

39、en from threeseparate spikes in the same lot, shall be a minimum of 15 ft-lbs.Testing shall be in accordance with Specification A 370. Thetest temperature shall be determined either by the lowestaverage temperature of the location where the spikes shall beused, or other temperature specified in the
