Abstract

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 degrees, 60 degrees or 85 degrees. The method is not suitable for the measurement of the gloss of metallic paints. a) The 60 degrees geometry is applicable to all paint films, but for very high gloss and near-matt films 20 degrees or 85" may be more suitable. b) The 20 degrees geometry, which uses a smaller receptor aperture, is intended to give improved differen- tiation between high-gloss paint films (i.e. films with a 60 degrees specular gloss higher than about 70 units). c) The 85 degrees geometry is intended to give improved differentiation between low-gloss paint films (i.e. films with a 60 degrees specular gloss lower than about 10 units). NOTES 1 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.
