Scope: 1.1 This standard is one of a series of standards on sampling and testing of paints, varnishes and related products. This standard specifies the test method for measuring the specular gloss of paint films with reflectometers at 20°, 60° or 85° geometry. This method is not applicable to the gloss measurement of paint films containing metallic pigments. a) The 60° geometry is suitable for all paint films, but for very high gloss and near-matt paint films, 20° or 85° may be more suitable. b) The 20° geometry (using smaller receiver apertures) gives better resolution in the case of high gloss paint films (ie films with a 60° specular gloss higher than 70 units). The c)/85° geometry gives better resolution in the case of low gloss paint films (ie, paint films with a 60° specular gloss of less than 10 units). Note 1: A uniform geometric condition should be maintained for the same series of measurements, even if it is not within the recommended geometric conditions. Note 2: In some cases, the measured value of specular gloss may not agree with the visual evaluation.
