Ball Impact Test
The impact test according to ASTM D 2794, EN ISO 6272-1; EN ISO 6272-2 is used for testing the impact resistance of powder coatings and can be carried out in our in-house test laboratory. Because this procedure is a destructive test, it is only done on samples.
A ball with a diameter of 15.9 mm is dropped onto the coated sample plate from a certain drop height. Looking at the coating, it should have only slight cracks and removal from the substrate is not permitted.
