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
