Standard Specification for Electrolytic Copper Cathode

ABSTRACT
This specification establishes the requirements for electrolytic copper cathode; electrorefined and electrowon. The cathode furnished shall conform to the chemical composition requirements specified. Cathodes shall withstand ordinary handling without breakage or excessive separation of nodules. They shall be substantially free of all foreign material; for example, copper sulfate, dirt, grease, and oil. Electrical resistivity of the cathodes shall be determined as the mean of results from four specimens.
SIGNIFICANCE AND USE
13.1 Calculated values shall be rounded to the desired number of places as directed in Practice E29.
SCOPE
1.1 This specification establishes the requirements for electrolytic copper cathode; electrorefined 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 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.  
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 health practices and determine the applicability of regulatory limitations prior to use.

A1.3.3.2 A gross sample of 24 cathodes, or the equivalent in sheared cathode pieces, shall be selected from a lot. To guarantee
random selection, all cathodes, or sheared cathode pieces, of the lot shall be individually numbered, and a random number
generator shall be used to select the individual test pieces.
A1.3.3.3 In the case of sheared cathodes, 24 full cathodes; 48 half-plate cathodes, 24 each of tops and bottoms; 96 quarter-plate
cathodes, and 24 each of the four quarters, shall be selected.
A1.3.3.4 The selection of test pieces of cathode sheared smaller than quarter plate shall be by agreement between the producer,
or the supplier, and the purchaser.
A1.3.3.5 Alternatively, to avoid individual numbering of cathodes, or sheared cathode pieces, in the case of large lots, provided
both parties agree, individual bundles, or containers, may be selected on a random basis, and then individual cathodes, or sheared
cathode pieces, within each bundle, or container, shall be numbered and test pieces selected, using a random number generator as
just described.
A1.4 Sample Preparation
A1.4.1 Cathode for Continuous Rod Casting:
A1.4.1.1 The portion used for flushing the system shall not be used for sampling.
A1.4.1.2 The remaining gross sample, minimum of one hour’s cast, shall be charged to the melting furnace. The rod coils
produced from the caster shall be sequentially numbered, excluding any coils with obvious defects normally attributed to the rod
casting process.
A1.4.1.3 Chemical Composition—Each party shall select 2 coils from which a segment of rod approximately 16 in. (406 mm)
(406 mm) in length shall be cut at the trailing ends of the coils. Each rod segment shall be cut into 4 portions of approximate equal
lengths. The 16 portions shall be divided into 4 groups; each group shall contain one portion from each of the 4 original rod
segments. The 4 groups of rod portions shall be placed in separate noncontaminating containers, then sealed and identified for the
supplier, the purchaser, contingency, and umpire if necessary.
A1.4.1.4 Electrical Resistivity—Each party shall select 2 coils from which a rod segment of sufficient length for test shall be taken
from the trailing ends of the coils. Each rod segment shall be cold drawn into a wire about 0.080 in. diameter (2.0 mm) and at
least 160 in. in length (4 m). Each wire coil shall
