Alcance
ISO 13803:2014 specifies a test method for determining the haze of coatings. The method is suitable for the haze measurement of non-textures coatings on plane, opaque substrates.The use of the 20� 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.
