1.1 This specification establishes the general requirements common to wrought copper and copper alloy rod, bar, shapes, and forgings which shall apply to Specifications B16/B16M, B21/B21M, B98/B98M, B124/B124M, B138/B138M, B139/B139M, B140/B140M, B150/B150M, B151/B151M, B196/B196M, B283, B301/B301M, B371/B371M, B411/B411M, B441, B453/B453M, B455, B570, and B927 to the extent referenced therein. 1.2 The chemical composition, physical and mechanical properties, and all other requirements not included in this specification are prescribed in the product specification. 1.3 The values stated in inch-pounds units or SI units are to be regarded separately in the standard. Within the text the SI values are given in brackets. The values stated in each system of units are not exact equivalents; each system is independent of the other. Combining values from the two systems may result in nonconformance with the specification. Note 1—Requirements for flat wire (defined as flat products up to and including 0.188 in. thick and up to 1¼ in. in width, with all surfaces rolled or drawn, without having been slit, sheared or sawed) including square, furnished in coils or straight lengths, or on spools, reels, or bucks are described by the wire Specifications B206/B206M and B272. 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. |
