ASTM D2794 is a standard test method used to evaluate the resistance of organic coatings to rapid deformation caused by impacts, determining their durability against cracking or flaking. The test measures the inch-pounds of force required to damage a coating on a substrate using a falling weight, commonly applied in automotive and construction industries for quality control.

ASTM D2794 is a standard test method developed by the American Society for Testing and Materials (ASTM) that covers the determination of the resistance of organic coatings to surface deterioration by sulfur dioxide (SO2) gas. The test is designed to evaluate the effects of SO2 on coatings, which can cause chalking, discoloration, and loss of gloss. ASTM D2794 is a standard test method used
A steel punch (typically 0.500 or 0.625 inches in diameter) is dropped onto the sample. Sample Conditioning: Panels are usually conditioned at relative humidity for at least 24 hours prior to testing. Limitations and Reliability ASTM D2794 is a standard
ASTM D2794 is a widely recognized standard test method that assesses the impact resistance of paints and coatings. The test, also known as the "Impact Resistance of Paints and Coatings" test, evaluates the ability of a paint or coating to withstand the effects of impact, such as cracking, flaking, or detachment from the substrate.
When purchasing, ensure you select the "Redline" version. This PDF shows changes from the previous version, which is invaluable for labs updating their procedures.
