1.1 本规范规定了用于屋顶、防水板和其他建筑应用的工厂生产的预钝化（人工老化）铜片和铜带的要求，以盎司重量或其他标准工厂规定的厚度为单位，以扁平长度供应。 1.2 预钝化表面是与铜发生化学反应的结果，应涂覆在产品的一侧。 1.2.1 形成的预镀铜表面在颜色和弯曲或成型能力方面与天然镀铜形成的表面相当。 1.3 预抛光表面不是工业应用的人造涂层的结果，类似于油漆或任何其他防止铜与气候相互作用的饰面。 1.4 根据本规范制造的材料不用于电气应用。 1.5 单位-- 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准值。 注1: 建筑用铜片和铜带的配套规范是规范 B370 . 1.6 以下安全隐患警告仅适用于测试方法部分，第节 12 ，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。 1.7 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 mill-produced pre-patinated (artificially aged) copper sheet and strip in ounce-weight or other standard mill-defined thicknesses supplied in flat lengths for roofing, flashing, and other architectural applications. 1.2 The pre-patinated surface is the result of chemical reaction with the copper and shall be applied on one side of the product. 1.2.1 The pre-patinated surface formed is comparable in color and ability to be bent or formed to the surface formed in naturally occurring patinated copper. 1.3 The pre-patinated surface is not the result of industrially applied artificial coatings, similar to paint or any other finishes that prevent interaction between the copper and the climate. 1.4 Materials made to this specification are not intended to be used for electrical applications. 1.5 Units— The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard. Note 1: A companion specification for copper sheet and strip for building construction is Specification B370 . 1.6 The following safety hazard caveat pertains only to the test method portion, Section 12 , 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. 1.7 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.
