This International Standard is one of a series of standards dealing with the sampling and testing of coating materials such as paints and varnishes, as well as coatings prepared from them. It specifies a test method for measuring at 20° the reflection haze of coatings. The use of this geometry means that the method is closely related to the measurement of gloss at 20° in ISO 2813. The application of this method is intended to give improved differentiation between high-gloss surfaces, for example in the field of assessment of dispersion characteristics. The method is therefore a useful complement to ISO 8781-3 which uses gloss measurements. For decorative coatings (e.g. automotive coatings), reflection haze is also an important criterion in evaluating the quality of the coating, in addition to colour and gloss. The results obtained often depend on the following properties of the coating materials: a) the binder system used and the composition of the paint; b) the wetting and dispersion properties of the pigments; c) the method of application; d) the orientation of the test specimen with respect to the plane of measurement.
