Paints and varnishes. Determination of gloss value at 20 degrees, 60 degrees and 85 degrees Ingestion-build-251241 Verifying straightness1 Scope This International Standard specifies a method for determining the gloss of coatings using the three geometries of 20, 60 or 85. The method is suitable for the gloss measurement of non textured coatings on plane, opaque substrates. NOTE On test specimens different from these mentioned above, comparative gloss measurements are possible. However, it is not ensured that the obtained gloss values correspond to the visual gloss perception (see
