适用范围：This Part specifies three methods for the measurement of the specular gloss of paint films, 20°, 60° and 85° geometry. The methods are not suitable for the measurement of the gloss of metallic paints.a) The 60° geometry method is applicable to all paint films but, for very high-gloss paints or those of near-matt sheen, the 20° or the 85° geometry method may be more suitable.b) The 20° geometry method is intended for obtaining improved differentiation of high-gloss paints, that is, those with a 60° gloss higher than 70 units.This does not mean, however, that the 60° geometry method cannot be used for paints having a 60° gloss higher than 70 units.c) The 85° geometry method is intended for obtaining improved differentiation of low-gloss paints, that is, those with a 60° gloss lower than 30 units.This does not mean, however, that the 60° geometry method cannot be used for paints having a 60° gloss lower than 30 units.1.2 Two procedures are given in Clause 4, the first (4.1) being for assessment of a film prepared from a liquid paint sample and the second (4.2) for assessment of an existing painted surface.
