ISO 2813:1994, Paints and varnishes - Determination of specular gloss of non-metallic paint films at 20 degrees, 60 degrees and 85 degrees

Specifies a test method for determining the specular gloss of paint films using a reflectometer geometry of 20�, 60� or 85�. The 60� geometry is applicable to all paint films, but for very high gloss and near-matt films 20� or 85� may be more suitable. The 20� geometry is intended to give improved differentiation between high-gloss paint films. The 85� geometry is intended to give improved differentiation between low-gloss paint films. The method is not suitable for the measurement of the gloss of metallic paints. This title may contain less than 24 pages of technical content.
