(Specification)Standard Specification for Electrolytic Copper Cathode
Standard Specification for Electrolytic Copper Cathode
SCOPE
1.1 This specification establishes the requirements for electrolytic copper cathode; electrorefined and electrowon.
1.2 The values stated in inch-pound units are the standard. SI values given in parentheses are for information only.
1.3 All references to sampling and analytical methods are for cases of dispute. Routine sampling and analysis shall be at the discretion of the supplier and the purchaser.
1.4 The following hazard caveat applies to the test methods described in Annex A2 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. Note 1-Cathode produced to this specification corresponds to the designation "Cath" as defined in Classification B224, and may be used to produce all other coppers listed in Classification B224 that are normally produced from "Cath" copper. Note 2-Grade 1 cathode conforms to the chemical compositional requirements of Copper UNS No. C11040, except for oxygen, and is suitable for the manufacture of wire rod as designated in Specification B49.
