Abstract
This specification covers grade 1 ( UNS C10100) and grade 2 (UNS C10200) of oxygen-free electrolytic copper wire bars, billets, and cakes produced without the use of metallic or metaloidal deoxidizers. The chemical composition of each grade shall be in accordance with the requirements specified. The maximum mass resistivity for grade 1 and grade 2 are presented. Grade 1 shall withstand ten reverse bends without breaking, in accordance with test method d of test methods B 577. Grade 2 shall withstand eight reverse bends without breaking in accordance with Test Method D of test methods B 577.
Scope
1.1 This specification establishes the requirements for two grades of oxygen-free electrolytic copper wire bars, billets, and cakes produced without the use of metallic or metaloidal deoxidizers.
1.2 Oxygen-free copper, as described herein, is defined as copper containing oxygen not in excess of 0.0010 % (10 ppm).
1.2.1 Grade 1 copper (UNS C10100) corresponds to the designation OFE in Classification B224.
1.2.2 Grade 2 copper (UNS C10200) corresponds to the designation OF in Classification B224.
1.2.3 Grade 2 copper may be used to produce OFS designation coppers corresponding to UNS C10400, C10500, and C10700.
1.3 Although this specification includes certain UNS designations as described in Practice E527, these designations are for cross reference only and are not specification requirements. In case of conflict, Specification B170 shall govern.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only, except for analytical measurements where SI units are the norm.
1.5 The following hazard caveat pertains only to Section 13 and Annex A1, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
