scope:

Is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products. It specifies a method for the visual comparison of the colour of films of paints and 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. It is not applicable to coatings containing special-effect pigments, e.g. metallics, without previous agreement on all details of illuminating and viewing conditions.
