1.1 本规范涵盖了铝和铝合金零件上电解形成的多孔氧化物涂层的要求，其中外观、耐磨性、电气性能和防腐至关重要。不包括用于电容器的无孔阻挡层阳极涂层。七种类型的涂层如所示 表1 提供。服务条件的定义和典型示例见 附录X1 . 注1: 人们认识到，可能需要对本规范所涵盖的涂层进行修改。 在这种情况下，买方所需的特定属性应为买方和制造商之间的协议主题。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 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 requirements for electrolytically formed porous oxide coatings on aluminum and aluminum alloy parts in which appearance, abrasion resistance, electrical properties, and protection against corrosion are important. Nonporous, barrier layer anodic coatings used for electrical capacitors are not covered. Seven types of coatings as shown in Table 1 are provided. Definitions and typical examples of service conditions are provided in Appendix X1 . Note 1: It is recognized that uses exist in which modifications of the coatings covered by this specification may be required. In such cases the particular properties desired by the purchaser should be the subject of agreement between the purchaser and the manufacturer. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.
