BS EN ISO 787-14:2019

This standard BS EN ISO 787-14:2019 General methods of test for pigments and extenders is classified in these ICS categories:

• 87.060.10 Pigments and extenders

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.
