This Japanese Industrial sSandard is one of a series of standards dealing with the sampling and testing of paints and related products. This Standard specifies the testing method for determining the specular gloss of paint using a reflectometer geometry of 20 degrees C, 60 degrees C or 85 degrees C. The method is not suitable for the measurement of the gloss of metallic paints. a) The 60 degrees C geometry is applicable to all paint films, but for very high gloss and near-matt films 20 degrees C or 85 degrees C may be more suitable. b) The 20 degrees C geometry, which uses a smaller receptor aperture, is intended to give improved differentiation between high-gloss paint films (i.e. films with a 60 dgrees C specular gloss higher than about 70 units). c) The 85 degrees C geometry is intended to give improved differentiation between low-gloss paint films (i.e. films with a 60 degrees C specular gloss lower than about 10 units).
