1.1 本规范涵盖了用于制造外科器械的锻造不锈钢的化学要求。中包含的数据 表1- 4. 本规范的，包括典型的硬度值、常见的热处理循环以及已用于外科器械的选定不锈钢的示例，仅供参考。机械性能要求、热处理要求、硬度要求以及除化学以外的所有其他要求均受以下参考或买方和供应商之间商定的适当材料标准的管辖。 1.2 本标准中的国际单位制为主要单位。以主要国际单位制或次要英寸表示的数值- 磅单位应单独视为标准单位。每个系统中规定的值可能不是完全相等的；因此，每个系统应相互独立使用。将两个系统的值结合起来可能会导致不符合标准。 1.3 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 covers the chemistry requirements for wrought stainless steels used for the manufacture of surgical instruments. The data contained in Tables 1- 4 of this specification, including typical hardness values, common heat treating cycles, and examples of selected stainless steels that have been used for surgical instruments, is provided for reference only. Mechanical property requirements, heat treating requirements, hardness requirements, and all other requirements except chemistry are governed by the appropriate material standards as referenced below or as agreed upon between the purchaser and supplier. 1.2 The SI units in this standard are the primary units. The values stated in either primary SI units or secondary inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of each other. Combining values from the two systems may result in nonconformance with the standard. 1.3 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.
