标准范围

该方法通常用于比较类似颜料，例如测试颜料与商定的参考颜料。颜料在规定的条件下分阶段分散在商定的粘合剂系统中。在每个阶段之后，取一部分磨机底座，制成一种组合物，应用于基材并干燥或烘干。每个干膜的镜面光泽度按照ISO 2813中所述进行测定。光泽度值以图形方式绘制为分散阶段的函数（例如，表示为时间、研磨机转数）。根据该图，确定了获得一致镜面反射值所需的色散功。

The method is of general use for comparing similar pigments, for example a test pigment against an agreed reference pigment. The pigment is dispersed in stages under specified conditions in an agreed binder system. After each stage, a portion of the mill base is taken and made into a composition that is applied to a substrate and dried or stoved. The specular gloss of each dried film is determined as described in ISO 2813. The gloss values are plotted graphically as a function of the dispersion stage (expressed for example as time, number of revolutions of a muller). From the graph, the dispersion work necessary to obtain an agreed specular reflection value is determined.
