Standard Practice for Sampling Wrought Nonferrous Metals and Alloys for Determination of Chemical Composition
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This practice covers the sampling, for the determination of chemical composition (Note 1), of nonferrous metals and alloys that have been reduced to their final form by mechanical working; that is, by such means as rolling, drawing, and extruding.
1.1.1 Refer to Practice E255 for copper and copper alloys.
Note 1--The selection of correct portions of material and the preparation of a representative sample from such portions are necessary prerequisites to every analysis, the analysis being of no value unless the sample actually represents the average composition of the material from which it was selected.
1.2 In special cases, when agreed upon by the purchaser and the manufacturer, the heat analysis may be accepted as representative of the composition of the finished product. In such cases, the identity of each heat of metal should be maintained through each stage of the manufacturing process to the final form. This method of sampling is not intended to apply under these conditions.
1.3 The values stated in inch-pound units are to be regarded as the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
