1.1 本规程涵盖了去除涂层样品的方法，以用于与通用涂层类型识别和失效分析或其他原因相关的后续分析。这些技术可用于现场、制造车间或实验室。 1.2 在实践中提出了获取重金属分析用涂层样品的方法 D5702 . 1.3 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.4 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。 1.5 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 分析样本必须充分采样、包装和记录，以从实验室获得有意义的信息。采样程序和包装将取决于采样原因。

1.1 This practice covers methods to remove samples of coating films for subsequent analysis related to identification of generic coating type and failure analysis or other reasons. These techniques can be used in the field, the fabricating shop, or laboratory. 1.2 The method for obtaining coating samples for heavy metal analysis is presented in Practice D5702 . 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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. 1.5 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 Specimens for analysis must be adequately sampled, packaged, and documented to obtain meaningful information from the laboratory. The sampling procedure and packaging will be dependent upon the reason for taking the sample.
