What is ISO 787-14- Pigments and extenders about?
ISO 787 discusses pigments and extenders. ISO 78714 is the fourteenth part of the ISO 787 multi-series and discusses the determination of resistivity of aqueous extract . ISO 787-14 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 ...
