The ASTM D2794 test procedure involves applying a paint or coating to a metal substrate, followed by subjecting the coated panel to a controlled impact using a specified apparatus. The impact is generated by dropping a weighted indenter onto the coated surface from a predetermined height. The test is typically performed on a panel of a specific size, and the coating is applied according to a specified thickness.
Automotive: Testing the stone-chip resistance of car body panels and bumpers.
ASTM D2794 is the standard test method for evaluating the impact resistance of organic coatings on metal substrates by measuring the energy required to cause failure. It involves dropping a standard weight onto an indenter on a coated panel to determine resistance to deformation, cracking, or peeling. Purchase the standard at ASTM International .
