scope:
This part of ISO 6504 describes methods for determining the opacity (by contrast ratio measurement) given by paint films of white or light colours of tristimulus value Y greater than 25, applied at a spreading rate of 20 m2/I to a black and white chart or to colourless transparent polyester foil. In the latter case, the tristimulus value Y is measured subsequently over black and white glass panels.
