A

2、number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers aluminum-alloy rolled flat

3、tread plate, mill-finish, with a raised pattern on one side, in thealloy, tempers, and thicknesses shown in Table 1 and Table 2Table 3.1.2 Alloy and temper designation are in accordance withANSI H35.1/H35.1M. The equivalent Unified NumberingSystem alloy designation are those of Table 1 preceded by A

4、9,which is A96061 for alloy 6061 and A93003 for Alloy 3003 inaccordance with Practice E 527.1.3 For acceptance criteria for inclusion of new aluminumand aluminum alloys in this specification, see Annex A2.1.4 The values stated in either inch-pound or SI units are tobe regarded separately as standard

5、. The SI units are showneither in brackets or in separate tables. The values stated ineach system are not exact equivalents; therefore, each systemmust be used independently of the other. Combining valuesfrom the two systems will result in nonconformance with thespecification.2. Referenced Documents

Chemical Composition7.1 LimitsThe tread plate shall conform to the chemicalcomposition limits specified in Table 1. Conformance shal

34、l bedetermined by analyzing samples taken at the time the ingotsare cast, or samples taken from the finished or semifinishedproduct. If the chemical composition of the material has beendetermined during the course of manufacture, additional sam-pling and analysis of the finished product shall not be

35、 neces-sary.NOTE 2It is standard practice in the United States aluminum industryto determine conformance to the chemical composition limits prior tofurther processing of ingots into wrought products. Due to the continuousnature of the process, it is not practical to keep a specific ingot analysiside

38、amplingSamples for determination ofchemical composition shall be taken in accordance with one ofthe following methods:7.3.1 Samples for chemical analysis shall be taken bydrilling, sawing, milling, turning, or clipping a representativepiece or pieces to obtain a prepared sample of not less than 75g.

39、 Sampling shall be in accordance with Practice E55.7.3.2 Sampling for spectrochemical analysis shall be inaccordance with Practices E 716.
