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。颜料在规定条件下在商定的粘合剂体系中分阶段分散。在每个阶段之后，取一部分磨机底座，并按照ISO 1524的规定测定其研磨细度。磨矿细度值以图形形式表示为所完成的分散功的函数（表示为时间、转数等）。从图中可以确定获得商定磨矿细度所需的功。

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 its fineness of grind is determined as described in ISO 1524. The fineness-of-grind values are plotted graphically as a function of the dispersion work done (expressed as time, number of revolutions, etc.). From the graph, the work necessary to obtain an agreed fineness of grind is determined.
