1.1 This specification establishes the requirements for electrolytic copper cathode; electrorefining and electrowon.
1.2 Units—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.

Note 1: Cathode produced to this specification corresponds to the designation Cath as defined in Classification B**4 and may be used to produce all other coppers listed in Classification B**4 that are normally produced from Cath copper.

Note 2: Grade 1 cathode conforms to the chemical compositional requirements of Copper UNS No. C****0, except for oxygen, and is suitable for the manufacture of wire rod as designated in Specification B*9.

1.3 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 heal.
