本文件规定了内墙涂料质量评估的两种现场测试方法（现场可清洁性【去污性】和现场耐湿擦洗性）。 这些测试方法适用于三刺激值Y10大于25的白色涂层和浅色涂层，所述三刺激值Y10是在由施加到黑色基底上的涂层组成的测试样本上测量的。 清洁性测试可以区分18%颜料体积浓度（PVC）和临界颜料体积浓度（CPVC）之间的涂层质量。现场耐湿擦洗试验方法可以区分PVC接近等于CPVC或以上时的涂层质量。

This document specifies two on-site test methods (on-site cleanability [stain removal] and on-site wet-scrub resistance) for the evaluation of the quality assessment for interior wall coatings. These test methods are applicable to white coatings and light-coloured coatings of tristimulus value Y₁₀ greater than 25 measured on a test specimen consisting of a coating applied to a black substrate. The cleanability test can differentiate the coating quality between 18 % of the pigment volume concentration (PVC) and the critical pigment volume concentration (CPVC). The on-site wet-scrub resistance test method can differentiate the coating quality when the PVC is nearly equal to the CPVC or above.
