1.1 This specification establishes the requirements for electrolytic copper cathode; electrorefined and electrowon.

1.2 UnitsThe values stated in inch-pound units are the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Note 1

Cathode produced to this specification corresponds to the designation "Cath" as defined in Classification B 224 and may be used to produce all other coppers listed in Classification B 224 that are normally produced from "Cath" copper.

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 B 49.

The following hazard caveat applies to the test methods described in 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.
