本文件规定了分别测定颜料水萃取物的电阻率（比电阻）或比电导率的一般试验方法。本方法适用于所有颜料和填充剂，但溶于水的颜料除外。颜料水萃取物的电阻率被认为是与水溶性物质的量无关的性质。如果同意，可以使用冷提取方法。

This document specifies a general method of test for determining the electric resistivity (specific electric resistance) or the specific electric conductivity, respectively, of the aqueous extract of a pigment. The method is applicable to all pigments and extenders, except pigments that are soluble in water. The resistivity of the aqueous extract of a pigment is considered as a property independent of the amount of water-soluble matter. If agreed, a cold extraction method can be used.
