4、les in T6, T61, T63, T64, T65, and H111tempers with Type B tolerances, as shown in the “List of ANSITables of Dimensional Tolerances.”1.1.2 Type CHot-finished rectangular bar in T6, T61, T63,T64, T65, and H111 tempers with Type C tolerances as listedin the tolerances and permissible variations table
5、s.1.2 Alloy and temper designations are in accordance withANSI H35.1. The equivalent Unified Numbering System alloydesignation in accordance with Practice E 527 is A96101 forAlloy 6101.NOTE 1Type A material, last covered in the 1966 issue of thisspecification, is no longer available; therefore, requ
6、irements for cold-finished rectangular bar have been deleted.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 SI or inch-pound units are tobe regarded separately as standard. The values stated in eachsyst
7、em may not be exact equivalents; therefore each systemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with thestandard.2.

Chemical Composition7.1 LimitsThe material sh
34、all conform to the chemicalcomposition limits in Table 1. Conformance shall be deter-mined by the producer by analyzing samples taken at the timeingots are poured, or samples taken from the finished orsemifinished product. If chemical composition has been deter-mined during the course of manufacture
35、, analysis of thefinished product shall not be required.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 pr
36、actical to keep a specific ingot analysisidentified with a specific quantity of finished material.7.2 Number of SamplesThe number of samples taken fordetermination of chemical composition shall be as follows:7.2.1 When samples are taken at the time the ingots arepoured, at least one sample shall be
37、taken for each group ofingots poured simultaneously from the same source of moltenmetal.7.2.2 When samples are taken from the finished or semifin-ished product, a sample shall be taken to represent each 4000lb (1800 kg), or fraction thereof, in the lot, except that not morethan one sample shall be r
38、equired per piece.7.3 Methods of SamplingSamples for determination ofchemical composition shall be taken in accordance with one ofthe following methods:7.3.1 Samples for chemical analysis shall be taken from thematerial by sawing, milling, turning, or clipping a representa-tive piece or pieces to ob
39、tain a prepared sample of not less than75 g. Sampling shall be in accordance with Practice E55.7.3.2 Sampling for spectrochemical analysis shall be inaccordance with Practices E 716. Samples for other methods ofanalysis shall be taken by methods suitable for the form ofmaterial being analyzed and th
40、e type of analytical methodused.7.4 Methods of AnalysisThe determination of chemicalcomposition shall be made in accordance with suitable chemi-cal (Test Methods E34) or spectrochemical (Test MethodsE 607 and E 1251), methods. Other methods may be used onlywhen no published ASTM method is available.
