Deals with the sampling and testing of paints, varnishes and related products. Defines a method for visually comparing the colour of films of paints or related products against a standard (either a reference standard or a freshly prepared standard) using either natural daylight or artificial light sources in a standard booth. Does not apply to coatings containing special-effect pigments, e.g. metallics, without previous agreement on all details of illuminating and viewing conditions.
