Provides procedures for determining the specular gloss of non-metallic paint films using a glossmeter. Identical with and reproduced from ISO2813:1994.

This International Standard is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products.It specifies a test method for determining the specular gloss of paint films using a reflectometer geometry of 20¦, 60¦ or 85¦. The method is not suitable for the measurement of the gloss of metallic paints.a) The 60¦ geometry is applicable to all paint films, but for very high gloss and near-matt films 20¦ or85 ¦ may be more suitable.b) The 20¦ geometry, which uses a smaller receptor aperture, is intended to give improved differentiation between high-gloss paint films (i.e. films with a 60¦ specular gloss higher than about 70 units).c) The 85¦ geometry is intended to give improved differentiation between low-gloss paint films (i.e. films with a 60¦ specular gloss lower than about 10 units).NOTES1 The same geometry should, of course, be retained for a series of measurements even if this means disregarding the suggested limits.2 In some cases, the determination of specular gloss may not correspond to a visual assessment.
