1.1 本试验方法涵盖了用刷子在模拟内墙部分的试板上涂覆涂料的光泽或光泽均匀性的测定。目视评估了由于湿边时间短、流平性差、颜料取向或浮选在涂抹期间和之后引起的光泽或光泽变化。 1.2 由于应用和小组评估都是非常主观的，因此该测试方法只能用于一个实验室内的比较测试，因为不同实验室分配的评级通常不一致（见 8.1 ). 1.3 以国际单位制给出的数值应视为标准。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 当涂层应用于大平面（如墙壁）时，当新材料的颜色与之前的膜非常相似时，膜厚度可能会变化，或者可能会完全遗漏小区域（漏涂）。 如果这些区域可以补漆，而不必重新油漆整个表面，那么成本就会低得多。 3.2 在之前短时间涂覆的区域与当前涂覆的区域（搭接）连接的位置，厚度也会受到影响。可能影响薄膜最终外观的应用技术是在相邻区域以不同方向刷涂或滚动材料。 3.3 买卖双方都有兴趣确定涂层是否可以在不显示因搭接和刷痕或辊痕而出现外观差异的区域的情况下进行涂覆，以及涂层是否可以容易地进行润色，以提供光泽或光泽以及所有其他方面的统一外观。

1.1 This test method covers the determination of the uniformity of gloss or sheen of a paint applied by brush to a test panel simulating an interior wall section. Variations in gloss or sheen that may be caused by short wet edge time, poor leveling, and pigment orientation or flotation during and after application are evaluated visually. 1.2 Because both the application and the panel evaluation are very subjective, this test method should be used only for comparative testing within one laboratory as the ratings assigned by different laboratories do not usually agree (see 8.1 ). 1.3 The values given 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 When coatings are applied to large flat surfaces such as walls, the film thickness may vary or there may be small areas missed entirely (holidays) when the color of the fresh material and the previous film are very similar. It is much less costly if these areas can be touched up instead of having to repaint the entire surface. 3.2 Thickness is also affected in the locations where an area coated a short time before is joined with the area currently being coated (laps). An application technique that may affect the final appearance of the film is brushing or rolling the material in different directions in adjacent areas. 3.3 Both buyers and sellers are interested in determining whether a coating can be applied without exhibiting areas that differ in appearance because of laps and brush or roller marks, and whether it can be readily touched up to provide a uniform appearance in regard to gloss or sheen and all other aspects.
