1. Scope | ||||||||||||||
1.1 This specification establishes the requirements for tough-pitch fire-refined copper wire bars, cakes, slabs, and billets for fabricating into wrought products and ingot and ingot bars for use in the manufacture of copper and copper alloy castings. This copper is not intended for electrical purposes. 1.2 Copper under this specification corresponds to the designation “FRTP” (UNS C12500) as shown in Classification B224. This copper may also be used to produce copper, corresponding to the designation “DPTE” (UNS C14520). 1.3 Although this specification includes certain UNS designations as described in Practice E527, these designations are for cross reference only and are not specification requirements. Therefore, in case of conflict, this ASTM specification shall govern. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 The following safety hazard caveat pertains only to the test method described in the annex of this specification: 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. A1.1.1 This test method covers the analysis of antimony, arsenic, bismuth, lead, nickel, selenium, and tellurium in tough-pitch fire-refined copper. A1.1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns 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. |
