Also listed are importantresidual elements.Analysis for elements not listed in Table 1 isnot required to verify compliance with this

30、 specification.7.2 Product Analysis:7.2.1 Product analysis tolerances do not broaden the speci-fied heat analysis requirements but cover variations betweenlaboratories in the measurement of chemical content. Themanufacturer shall not ship material that is outside the limitsspecified in Table 1. The

31、product analysis tolerances shallconform to the product tolerances in Table 2.6Available from American Society for Quality (ASQ), 600 N.

33、either for the purpose ofverifying the composition of a heat or manufacturing lot or todetermine variations in the composition within the heat.7.2.3 Acceptance or rejection of a heat or manufacturing lotof material may be made by the purchaser on the basis of thisproduct analysis. Product analyses o

34、utside the tolerance limitsallowed in Table 2 are cause for rejection of the product. Areferee analysis may be used if agreed upon by the supplier andpurchaser.7.2.4 For referee purposes, use Test Methods, E539, E1409,E1447, E1941, and E2371 or other analytical methods agreedupon between the purchas

35、er and the supplier.7.3 Samples for chemical analysis are representative of thematerial being tested. The utmost care must be used insampling titanium for chemical analysis because of its affinityfor elements such as oxygen, nitrogen, and hydrogen. Incutting samples for analysis, therefore, the oper

Mechanical Requirements8.1 The material supplied under this specification shallconform to the mechanical property requireme

37、nts in Table 3 orTable 4.8.2 Specimens for tension tests shall be machined and testedin accordance with Test Methods E8/E8M.

The lot shall beconsidered in compliance only if all additional test pieces meetthe specified requirements.8.4.2 Tensile test results for which any specimen fracturesoutside the gauge leng

41、th shall be considered acceptable if boththe elongation and the reduction of area meet the minimumrequirements specified. Refer to sections 7.11.4 and 7.12.5 ofTest Methods E8/E8M. If either the elongation or reduction ofarea is less than the minimum requirement, discard the test andretest. Retest o

42、ne specimen for each specimen that did not meetthe minimum requirements.8.4.3 Sheet, Strip, and PlateTest according to Test Meth-ods E8/E8M. Perform at least one tension test from each lot inthe longitudinal direction. Perform at least one bend test fromeach lot in both the longitudinal and transver

43、se directions.Testsin the transverse direction need be made only on product fromwhich a specimen not less than 200 mm (8.0 in.) in length forsheet, and 64 mm (2.50 in.) in length for plate can be taken.Should any of these test pieces not meet the specifiedrequirements, test two additional test piece
