    1. Scope

    1.1 This specification covers 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).

    1.3 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 11 and Annex, of this specification. This standard does not purport to address all of the safety problems, 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.
