ASTM updates standards roughly every 5–8 years. The current active version of (last reapproved in 2019, but always check the latest) may have changed the required mass of the weight or the inspection lighting conditions. A 1993 PDF is not valid today. Raise the weight to a height where no
ASTM D2794 is a widely used test method for evaluating the resistance of organic coatings to the effects of rapid deformation. The test provides valuable information on the impact resistance of coatings, which can be used to predict their performance in real-world applications. The test method is reliable, reproducible, and widely applicable to a range of coatings. A 1993 PDF is not valid today
By understanding and correctly applying ASTM D2794, coating manufacturers and end-users can quantify "toughness" with scientific rigor. Whether you are testing automotive clearcoats, industrial enamels, or powder coatings, this standard remains the definitive method for rapid deformation resistance.
