标准范围
本文件规定了分别测定颜料水提取物电阻率(比电阻)或比电导率的一般试验方法。本方法适用于除可溶于水的颜料外的所有颜料和填充剂。颜料水提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.
