ISO 2813:1994 PDF

Scope: This standard is one of a series of standards related to the sampling and testing of paints, varnishes and related products. This standard specifies the test method for measuring the specular gloss of colored paint films using a reflectometer at 20°, 60° or 85° geometric conditions. This method is not suitable for gloss measurement of paint films containing metallic pigments. a) The 60° geometry applies to all paint films, but for very high gloss and nearly matte paint films, 20° or 85° may be more suitable. b) The 20° geometry (using a smaller receiver aperture) gives better resolution in the case of high-gloss paint films (i.e. paint films with a specular gloss of 60 units higher than 70 units). c) The 85° geometric condition can give better resolution for low-gloss paint films (that is, paint films with a 60° specular gloss less than 10 units). NOTE 1: Uniform geometric conditions should be maintained for the same series of measurements, even if they are outside the recommended geometric conditions. Note 2: In some cases. Specular gloss measurements may differ from visual assessments.
