ISO 23900-2:2015规定了测定测试颜料相对于标准的颜色特性的方法，以及颜料在各种条件下分散着色材料的颜色强度的差异在增塑聚氯乙烯中的分散DHPVC-P的容易程度（PVC-P）化合物。 该方法适用于有机和无机黑色和彩色颜料以及颜料制剂。

ISO 23900-2:2015 specifies a method of determining the colouristic properties of a test pigment relative to a standard, and the ease of dispersion DHPVC-P of pigments from the differences in colour strength on dispersing colouring materials under various conditions in plasticized polyvinyl chloride (PVC-P) compounds. The method is appropriate for use with organic and inorganic black and colour pigments and for pigment preparations.
