DESCRIPTION
BS EN ISO 20566:2021
This standard BS EN ISO 20566:2021 Paints and varnishes. Determination of the scratch resistance of a coating system using a laboratory-scale car-wash is classified in these ICS categories:
- 43.020 Road vehicles in general
- 87.040 Paints and varnishes
This document specifies a test procedure for assessing the scratch resistance of organic paint coatings, in particular paint coatings used in the automotive industry (i.e. for assessing their car-wash resistance). Machine-based washing is 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.
