The Impact Test ASTM D2794 involves the following steps: By subjecting organic coatings to rapid deformation, it

ASTM D2794 remains a cornerstone of coatings evaluation because it addresses the fundamental unpredictability of physical interaction. By subjecting organic coatings to rapid deformation, it strips away the theoretical assumptions of laboratory chemistry and subjects the material to the unforgiving laws of physics. Whether preventing corrosion on a bridge girder struck by a maintenance tool or ensuring a washing machine cabinet survives the manufacturing line, the impact resistance test validates the coating’s ability to function as a protective shield. Ultimately, ASTM D2794 ensures that the finish on a product is not merely cosmetic, but a resilient barrier capable of enduring the rigors of the real world.

The procedure involves a "pass-fail" approach that gradually increases in intensity until failure occurs:
