Paints and varnishes - Determination of the scratch resistance of a coating system using a laboratory-scale car-wash (ISO 20566:2013)
|Publication Date:||1 June 2013|
|ICS Code (Paints and varnishes):||87.040|
This International Standard describes a test procedure for assessing the scratch resistance of organic paint coatings1), in particular paint coatings used in the automotive industry (i.e. for assessing their car-wash resistance). Machine-based washing in simulated in the laboratory environment using a rotating brush and synthetic dirt. The test conditions have been designed to be as close as possible to the real conditions in a car-wash. If the test parameters are suitably chosen, the method can also be used for testing protective plastics films and plastics components.
