1.1 本规范涵盖不锈钢零件的几种不同类型的化学钝化处理。它包括不锈钢零件除垢、清洁和钝化的建议和预防措施。它包括几个替代试验，以及验收标准，以确认此类处理对不锈钢零件的有效性。 1.2 在实践中更深入地讨论了不锈钢表面的机械和化学处理实践 A380/A380M . 1.3 定义了几种用于不锈钢零件钝化的替代化学处理方法。 附录X1和 附录X2 提供一些非强制性信息，并提供一些关于选择适合特定等级不锈钢的钝化处理的一般指南。 本规范未对任何特定应用或应用类别的任何等级、处理或验收标准的适用性提出任何建议。 1.4 本规范中的试验旨在确认钝化的有效性，特别是在去除游离铁和其他外源物质方面。这些测试包括以下实践: 1.4.1 练习A- 浸水试验， 1.4.2 实践B- 高湿度试验， 1.4.3 实践C- 盐雾试验， 1.4.4 实践D- 硫酸铜试验， 1.4.5 练习E- 铁氰化钾硝酸试验，以及 1.4.6 实践F- 湿布试验，以及 1.4.7 练习G- 沸水浸泡试验。 注1: 游离铁表示零件表面存在的铁，包括但不限于铁污染、铁- 工具痕迹、酸洗溶液中残留的铁盐、铁屑、大气暴露、焊缝中的铁沉积物、嵌入铁和氧化铁。 1.5 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；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。 1.6 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。 1.7 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 covers several different types of chemical passivation treatments for stainless steel parts. It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts. It includes several alternative tests, with acceptance criteria, for confirmation of effectiveness of such treatments for stainless steel parts. 1.2 Practices for the mechanical and chemical treatments of stainless steel surfaces are discussed more thoroughly in Practice A380/A380M . 1.3 Several alternative chemical treatments are defined for passivation of stainless steel parts. Appendix X1 and Appendix X2 give some nonmandatory information and provides some general guidelines regarding the selection of passivation treatments appropriate to particular grades of stainless steel. This specification makes no recommendations regarding the suitability of any grade, treatment, or acceptance criteria for any particular application or class of applications. 1.4 The tests in this specification are intended to confirm the effectiveness of passivation, particularly with regard to the removal of free iron and other exogenous matter. These tests include the following practices: 1.4.1 Practice A— Water Immersion Test, 1.4.2 Practice B— High Humidity Test, 1.4.3 Practice C— Salt Spray Test, 1.4.4 Practice D— Copper Sulfate Test, 1.4.5 Practice E— Potassium Ferricyanide-Nitric Acid Test, and 1.4.6 Practice F— Damp Cloth Test, and 1.4.7 Practice G— Boiling Water Immersion Test. Note 1: Free iron denotes iron present on the surface of the parts, including but not limited to iron contamination, iron-tool marks, residual-iron salts from pickling solutions, iron dust, atmospheric exposure, iron deposits in welds, embedded iron, and iron oxide. 1.5 The values stated in either SI units or 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 the other. Combining values from the two systems may result in non-conformance with the standard. 1.6 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. 1.7 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.
