(Practice)Standard Practice for Sampling Copper and Copper Alloys for the Determination of Chemical Composition
Standard Practice for Sampling Copper and Copper Alloys for the Determination of Chemical Composition
SCOPE
1.1 This practice describes the sampling of copper (except electrolytic cathode) and copper alloys in either cast or wrought form for the determination of composition.
1.2 Cast products may be in the form of cake, billet, wire bar, ingot, ingot bar, or casting.
1.3 Wrought products may be in the form of flat, pipe, tube, rod, bar, shape, or forging.
1.4 This practice is not intended to supersede or replace existing specification requirements for the sampling of a particular material.
1.5 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are given for information only.
1.6 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. A specific precautionary statement appears in Appendix X4.
