标准范围

指定用于确定涂层材料对比度达到98%所需的扩展速率的方法。该方法仅限于三刺激值为Y70的漆膜；它不适用于荧光或金属涂料材料。该方法的原理基于Kubelka和Munk方程，该方程将着色膜的散射和吸收系数与其颜色和不透明度联系起来。为了确定遮盖力，需要黑色背景上厚度为t的膜的反射率和反射率。

Specifies a method to be used for determining the spreading rate necessary to give a contrast ratio of 98 % of coating materials. The method is restricted to paint films having the tri-stimulus value of Y 70; it is not applicable to fluorescent or metallic paint materials. The principle of the method is based on the Kubelka and Munk equations relating the scattering and absorption coefficients of pigmented films to their colour and opacity. For the determination of hiding power, both the reflectance of a film of thickness, t, on a black background and the reflectivity are required.
