1.1 本规范规定了铜合金UNS编号C67000、C67500或C67600生产的锰青铜棒、棒和型材的要求。 1.2 单位- 标准中以英寸-磅单位或国际单位表示的数值应单独考虑。在文本中，SI值显示在括号中。每个单位制中规定的数值可能不是精确的等价物；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.3 警告- 许多监管机构已将汞指定为一种危险物质，可导致严重的医疗问题。汞或其蒸汽已被证明对健康有害，并对材料具有腐蚀性。 处理汞和含汞产品时应小心。有关更多信息，请参阅适用的产品安全数据表（SDS）。用户应意识到，法律可能禁止向您所在的州或国家销售汞和/或含汞产品。 注1: 适用于热锻应用的产品规格如下 B124/B124M . 1.4 以下安全隐患警告仅适用于本规范的性能要求部分。 1.4.1 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，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（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 manganese bronze rod, bar and shapes produced in Copper Alloy UNS Nos. C67000, C67500, or C67600. 1.2 Units— The values stated in inch-pound units or SI units are to be regarded separately in the standard. Within the text, the SI values are shown in brackets. The values stated in each system of units may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 Warning— Mercury has been designated by many regulatory agencies as a hazardous material that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Safety Data Sheet (SDS) for additional information. Users should be aware that selling mercury and/or mercury containing products into your state or country may be prohibited by law. Note 1: Product suitable for hot forging applications is available under Specification B124/B124M . 1.4 The following safety hazard caveat pertains only to the Performance Requirements section of this specification. 1.4.1 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 and health 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.
