scope:
The method specified provide an instrumental alternative of 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 samewhite 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 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.
