The standard specifies 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/l to an agreed black and white chart or to coulourless transparent polyester foil, in the latter case the tristimulus value Y beeing measured subsequently over agreed black and white glass panels.
