Paints and varnishes — Comparison of contrast ratio (hiding power) of paints of the same type and colour
Specifies the standard method to be used in comparing the contrast ratios given by paint films of white or ligth colours, of refelctance factor greater than 40 %, dried at normal air temperature and applied at approximately equal wet film thickness to black and white substrates. The wet film thickness selected, approximately 50 um, corresponds to a spreading rate of approximately 20 m2/l. Because different operators using the same film coating device obtain films differing in thickness the method is not satisfactory as an absolute method for the determination of hiding power.
