标准范围

规定方法的原理是将试验颜料和商定的参考颜料分散在特定的试验介质（醇酸树脂和气相二氧化硅的混合物）中，从分散液中在合适的基质上制备试样，测量ISO 7724-2中所述试样的三刺激值，计算ISO 7724-3中所述的适当颜色特性。

The principle of the method specified is dispersing the test pigment and an agreed reference pigment in a particular test medium (mixture of an alkyd resin and fumed silica), preparing specimens on suitable substrates from the dispersions, measuring the tristimulus values of the specimens as described in ISO 7724-2, calculating the appropriate colour characteristics as described in ISO 7724-3.
