The EN ISO 13803-2014 standard specifies a method for determining the gloss of Paints and varnishes films at 20 ° C. This method is suitable for gloss measurement of non-textured coatings on flat, opaque substrates. It is related to the 20 ° gloss measurement method in ISO 2813 and aims to improve the discrimination between high Gloss surfaces. The haze value is calculated by measuring the intensity of diffused light next to the mirror reflection direction of the coated surface. The lower the haze value, the smoother and clearer the surface.
