1.1 本试验方法包括通过使用研磨剂或非研磨性清洁剂清洗，测定去除内部涂层干膜上的污物变色的相对容易程度。 1.2 本试验方法仅限于CIE-Y反射率为60的涂层 % 或更多，根据试验方法测量 E1347 . 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====== 5.1 室内建筑涂料经常因污垢和其他污物材料而变色。本试验方法涵盖了通过擦洗从此类表面去除特定污物的相对容易性和完整性。土壤清除的难度越大，膜侵蚀越小，预期使用寿命越长。 5.2 通过该试验方法获得的结果不一定与所有类型的土壤剂相关。 5.3 半光泽饰面通常只需要非研磨型清洁剂，以有效去除污垢，而平漆可能需要研磨型清洁剂。

1.1 This test method covers the determination of the relative ease of removing soilant discolorations from the dried film of an interior coating by washing with either an abrasive or nonabrasive cleaner. 1.2 This test method is limited to coatings having a CIE-Y reflectance of 60 % or more, as measured in accordance with Test Method E1347 . 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 ====== 5.1 Interior architectural paints are often discolored by dirt and other soilant materials. This test method covers the relative ease and completeness of removal of a specific soilant from such a surface by scrubbing. The greater the ease of soil removal with a minimum of film erosion, the greater the useful service life is expected to be. 5.2 Results obtained by this test method do not necessarily correlate with all types of soilants. 5.3 Semigloss finishes generally require only the nonabrasive type cleaner for good soilant removal, whereas flat paints may require the abrasive type.
