1.1 本试验方法包括测定阳极涂层铝及其合金上每单位面积涂层的质量。 1.2 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、健康和环境实践，并确定监管限制的适用性。 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。 ====意义和用途====== 3.1 本试验方法是一种破坏性试验程序，适用于阳极涂层铝和铝合金涂层质量的制造操作中的质量控制。涂层质量是其厚度的近似值，前提是涂覆涂层的条件或涂层的密度已知。 阳极涂层的保护值和通过染色或电解方法着色的适应性与单位面积的涂层质量有关。

1.1 This test method covers determination of the mass per unit area of coating on anodically coated aluminum and its alloys. 1.2 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. 1.3 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. ====== Significance And Use ====== 3.1 This test method is a destructive test procedure suitable for quality control within manufacturing operations for coating mass on anodically coated aluminum and aluminum alloys. The mass of the coating is an approximation of its thickness provided the conditions under which the coating was applied, or the density of the coating, are known. An anodic coating's protective value and amenability to coloring by dying or electrolytic methods are related to mass of coating per unit area.
