It is strongly recommended to restrict numerical values to tests performed within a single lab. For comparing results between different locations, it is better to use ranking rather than exact numerical values. Where to Find the ASTM D2794 PDF
The test uses a cylindrical weight (often 1 kg or 2 lbs) that slides down a vertical guide tube.

ASTM D2794, the "Standard Test Method for Resistance of Organic Coatings to the Effects of Rapid Deformation (Impact)," is a test method developed by ASTM International. It specifically outlines a procedure for rapidly deforming an organic coating film and its metal substrate using a falling-weight impact tester. The primary goal is to assess the coating's resistance to cracking, flaking, or adhesion loss when subjected to a sudden, high-velocity impact, which is crucial for predicting real-world performance. Over the years, this standard has proven invaluable for ensuring quality and durability in industries ranging from automotive and appliance manufacturing to construction and industrial equipment.
Precision in Parameters: The standard specifies the exact dimensions of the indenter (typically 0.625 inches) and the weight of the falling hammer.
