Metode generale de încercare pentru pigmenţi şi materiale de umplutură. Partea 24: Determinarea puterii relative de colorare a pigmenţilor coloraţi şi a puterii relative de difuzie a pigmenţilor albi. Metoda fotometrică

The method specified provide an instrumental alternative to those described in ISO 787/16 and ISO 787/17. Equal masses of a coloured material are separately dispersed in the same mass of the same white pigment paste. The reflectivity of each dispersion is measured photometrically. From the corresponding values of K/S the relative tinting strength is given. For measurement of the relative scattering power equal masses of a white test material and an agreed reference pigment are separately dispersed in the same mass of the same black pigment paste. The reflectivity of each dispersion is measured photometrically at 550 nm. From the corresponding values of K/S the relative scattering power is given.
