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
