Standard Specification for Copper Rod Drawing Stock for Electrical Purposes
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers the requirements for rod drawing stock produced from electrolytic tough-pitch or oxygen-free coppers and is suitable for further fabrication into electrical conductors. The rod shall be fabricated from copper of such quality and purity. Copper of special qualities, forms, or types, as agreed upon between the manufacturer and the purchaser and that will conform to the requirements prescribed in this specification may also be used. The specimen shall have the following chemical composition: tellurium, selenium, bismuth, antimony, arsenic, tin, lead, iron, nickel, sulfur, silver, oxygen, cadmium, phosphorus, zinc, and manganese. Embrittlement test shall be performed on the specimen to reflect propensity towards hydrogen embrittlement and shall be performed only on oxygen-free copper. The rod shall be free of defects, but blemishes of a nature that do not interfere with the intended application are acceptable.
Scope
1.1 This specification covers the requirements for rod drawing stock in diameters from ¼ to 13/8 in. (6.4 to 35 mm) produced from electrolytic tough-pitch or oxygen-free coppers and are suitable for further fabrication into electrical conductors.
1.2 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.
1.3 The following safety hazards caveat pertains only to Section 13. 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.
