1.1 本规范规定了不使用金属或金属脱氧剂生产的两级无氧电解铜线棒、坯料和饼的要求。 1.2 如本文所述，无氧铜定义为含氧不超过0.0010的铜 % （10 ppm）。 1.2.1 1级铜（UNS C10100）对应于分类中的OFE名称 B224页 . 1.2.2 2级铜（UNS C10200）对应于分类中的名称 B224页 . 1.2.3 2级铜可用于生产与UNS C10400、C10500和C10700相对应的OFS标志铜。 1.3 尽管本规范包括实践中所述的某些UNS名称 E527 ，这些名称仅供交叉参考，不是规范要求。如有冲突，请说明 B170型 应适用。 1.4 以英寸表示的值- 磅单位应视为标准。括号中给出的值仅供参考，但以国际单位制为标准的分析测量除外。 1.5 以下危险警告仅适用于第 13 和 附件A1 ，符合本规范。 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

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.
