Provides a procedure for determining the pigment content of solvent-borne paints.

This Standard sets out a method of determining the pigment content of solvent-borne and water-borne paints. It is not suitable for some paints whose resins exist as solvent-borne emulsions, such as polyvinylidene fluoride (PVDF), or for non-aqueous dispersions (NAD). The method may not be suitable for paints containing pigments and extenders of very fine particle size such as colloidal silica, carbon black and some organic pigments.
