1.1 本规范规定了由UNS铜制成的锻造和预制形状的要求 2. 编号C10100，符合规范的化学要求 B170 ，1级，适用于电子设备。 1.2 本规范的要求是对以下适用于订购材料的产品规范中规定的要求的补充: 地下一层 , 地下二层 , 地下三层 , B75/B75米 , B152/B152M , B170 , B187/B187M , B188 , B272 ，以及 B372 然而，若存在冲突，应以本规范为准。 1.3 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对国际单位制的数学转换，仅供参考，不被视为标准值。 1.3.1 例外情况-- 粒度以公制单位表示，是标准的。 1.4 以下安全隐患警告适用于以下部分 17.4 , 17.5 和 18.7 根据本规范: 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。 本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification establishes the requirements for wrought and fabricated shapes made from Copper UNS 2 No. C10100, conforming to the chemical requirements of Specification B170 , Grade 1, and suitable for use in electron devices. 1.2 The requirements of this specification are in addition to those prescribed in the following product specifications appropriate to the material being ordered: B1 , B2 , B3 , B75/B75M , B152/B152M , B170 , B187/B187M , B188 , B272 , and B372 . In case of conflict, however, this specification shall take precedence. 1.3 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. 1.3.1 Exception— grain sizes are in metric units and are standard. 1.4 The following safety hazard caveat applies to sections 17.4 , 17.5 and 18.7 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. 1.5 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.
