適用范圍：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 greater than 25, applied at a spreading rate of to a black and white chart or to colourless transparent polyester foil. In the latter case, the tristimulus value is measured subsequently over black and white glass panels.
