ISO 23900-1:2015介绍了ISO 23900的各个部分，其中描述了在塑料材料中分散颜料和填充剂的方法，以确定其分散特性和着色性能。ISO 23900后续部分描述了评估分散特性的方法。 所述的各种程序允许在类似颜料之间进行比较（例如，在测试样品和商定的参考颜料之间）。如果试验程序和选择的塑料材料合适，试验结果表明了实际使用条件下的相对分散性。

ISO 23900-1:2015 provides an introduction to the various parts of ISO 23900 which describe methods for dispersing pigments and extenders in plastics materials in order to determine their dispersion characteristics and colouristic properties. Methods of assessing dispersion characteristics are described in the subsequent parts of ISO 23900. The various procedures described permit comparison to be made between similar pigments (for example between a test sample and an agreed reference pigment). The results provide an indication of relative dispersibility under practical conditions of use, provided that the test procedure and plastics material selected are appropriate.
