标准摘要
[中文适用范围]： 本文件规定了内墙涂料质量评估的两种现场测试方法（现场清洁性[去污]和现场耐湿擦洗性）。 这些测试方法适用于在由涂敷到黑色基材上的涂层组成的测试样本上测得的三刺激值Y10大于25的白色涂层和浅色涂层。 可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。 当PVC与CPVC接近或以上时，现场耐湿擦洗测试方法可以区分涂层质量。 [外文原描述]： 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 Y 10 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.
