One in a series of standards addressing testing and sampling of varnishes, paints and related products. Determination of pigment content of paints in which potassium hydroxide solution is added to coagulate the pigment and the resulting solids filtered off. Applicable to coating materials containing carbon black, very finely divided titanium dioxide, very finely divided silicon dioxide, polymer dispersions or organic pigments. It is not applicable to many water-diluted paints because the whole binder will coagulate when the potassium hydroxide solution is added. A centrifuge method can also be used to determine the pigment content of coating material (See ISO 14680-1) or by an ashing method (See ISO 14680-2).
