1.1 本规范规定了以下合金的黄铜（铜锌合金）板、薄板、带材和轧制棒材的要求: 铜合金 UNS编号。 金属类型 C21000 镀金 C22000 商业青铜 C22600 Jewerly青铜 C23000 红黄铜 C24000 低黄铜 C26000 盒式黄铜 C26800 黄色黄铜 C27200 … C28000 蒙茨金属 1.2 单位-- 以英寸磅单位或国际单位制表示的数值应单独视为标准。在正文中，国际单位制显示在括号中。每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。将两个系统的值合并可能导致不符合标准。 1.3 以下安全隐患警告仅适用于本规范中描述的测试方法。 1.3.1 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.4 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 brass (copper-zinc alloy) plate, sheet, strip, and rolled bar of the following alloys: Copper Alloy UNS No. Type of Metal C21000 Gilding C22000 Commerical Bronze C22600 Jewerly Bronze C23000 Red Brass C24000 Low Brass C26000 Cartridge Brass C26800 Yellow Brass C27200 … C28000 Muntz Metal 1.2 Units— The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3 The following safety hazard caveat pertains only to the test method(s) described in this specification. 1.3.1 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. 1.4 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.
