For directly coated panels, the determination of the degree of gloss is specified in EN 14323 (current edition 2004-06-01). Then the degree of gloss is to be determined with a so-called reflectometer according to ISO 2813. The principle of the reflectometer is based on the measurement of the directed reflection.
