: Coatings are applied to thin, 24-gauge metal panels (typically steel or aluminum) and allowed to cure fully before testing. Rapid Deformation
ASTM D2794 outlines the standard test method for evaluating the impact resistance of organic coatings by measuring their ability to withstand rapid deformation without cracking. The procedure involves dropping a specified weight onto a coated substrate to determine the threshold for film failure, critical for quality control in industries like automotive and coating manufacturing.
