This standard BS 3900-D6:1982 Methods of test for paints. Optical tests on paint films is classified in these ICS categories:
  • 87.040 Paints and varnishes

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.
