英文名称:Paints and varnishes — Comparison of contrast ratio (hiding power) of paints of the same type and colour

标准范围
规定了用于比较白色或浅色、反射系数大于40%、在正常空气温度下干燥并以大致相同的湿膜厚度施涂到黑白基底上的漆膜给出的对比度的标准方法。选择的湿膜厚度约为50μm,对应于约20 m2/l的铺展率。由于使用相同涂膜装置的不同操作员获得的膜厚度不同,因此该方法不能作为确定遮盖力的绝对方法。
Specifies the standard method to be used in comparing the contrast ratios given by paint films of white or ligth colours, of refelctance factor greater than 40 %, dried at normal air temperature and applied at approximately equal wet film thickness to black and white substrates. The wet film thickness selected, approximately 50 um, corresponds to a spreading rate of approximately 20 m2/l. Because different operators using the same film coating device obtain films differing in thickness the method is not satisfactory as an absolute method for the determination of hiding power.
