DIN 55603:2003 Testing of pigments - Determination of relative tinting strength and of colour difference on reduction of inorganic pigments using the lightness method
The method described in this standard is used for the determination of relative tinting strength and of colour difference on reduction of inorganic pigments. The relative tinting strength specified in this standard is the mass relation of reference- and test pigment weight, were the colour difference between reference and test ligthening has a minimum by visuell comparision.#,,#
