1.1 本规程涵盖涂漆钢表面锈蚀程度的评估。书面规范中给出的描述锈蚀百分比的视觉示例构成标准的一部分。如有争议，以书面定义为准。这些视觉示例是与SSPC合作开发的:保护涂层协会，以进一步标准化方法。这些照片可用于估计各种基材上其他涂层缺陷的百分比。本标准不包括评估最初准备的划线、刻痕或漏涂处周围的锈迹传播。 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 漆膜下方或穿过漆膜的锈蚀量是决定是否应维修或更换涂层系统的一个重要因素。本规程为量化可见表面锈蚀的数量和分布提供了标准化方法。 3.2 根据可见表面锈蚀的百分比，使用0到10个刻度来评估锈蚀程度。 3. 3. 锈病的分布可分为斑点锈病、一般锈病、点状锈病或混合锈病。

1.1 This practice covers the evaluation of the degree of rusting on painted steel surfaces. The visual examples which depict the percentage of rusting given in the written specifications form part of the standard. In the event of a dispute, the written definition prevails. These visual examples were developed in cooperation with SSPC: The Society for Protective Coatings to further standardization of methods. The photographs can be used to estimate the percentage of other coating defects on various substrates. This standard does not include evaluation of rust propagation around an initially prepared scribe, score, or holiday. 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 The amount of rusting beneath or through a paint film is a significant factor in determining whether a coating system should be repaired or replaced. This practice provides a standardized means for quantifying the amount and distribution of visible surface rust. 3.2 The degree of rusting is evaluated using a zero to ten scale based on the percentage of visible surface rust. 3.3 The distribution of the rust is classified as spot rust, general rust, pinpoint rust or hybrid rust.
