This International Standard specifies a method to be used for determining the opacity (by contrast ratio measurement) given by paint films of white or light colours of reflectance value greater than 25 %, applied at a spreading rate of 20 m2/l to colourless transparent polyester film, the reflectance being measured subsequently over agreed black and white glass plates.
Specifies a method for determining opacity of white or light-coloured paint films.
