Astm D2794 Pdf [better] Jun 2026
Understanding the test helps you appreciate why the PDF is so necessary. The ASTM D2794 procedure uses a simple but precise apparatus.
is the standard test method for the Resistance of Organic Coatings to the Effects of Rapid Deformation (Impact) . It was developed by ASTM International (formerly the American Society for Testing and Materials) to provide a standardized procedure for measuring a coating’s ability to resist cracking when a substrate is suddenly bent, stretched, or impacted.

: A standard weight is dropped from a measured distance through a guide tube to strike an indenter. Deformation Types Direct Impact : The weight strikes the coated side of the panel. Indirect (Reverse) Impact
: The weight strikes the uncoated side of the panel, causing the coating to bulge outward. Increasing Stress Understanding the test helps you appreciate why the
| Standard | Key Difference | | :--- | :--- | | | Uses a falling weight on a flat panel. Results in in-lb or Joules. | | ISO 6272-1 | Similar falling weight test, but uses a different indenter size (20 mm vs. ½ inch). | | ASTM D5420 | For rigid plastic substrates, not organic coatings. | | ASTM G14 | Specifically for pipe coatings (uses a different striker geometry). |
The test involves dropping the standard weight from increasing heights until the coating fails. How to Test Impact Resistance of Paints? It was developed by ASTM International (formerly the
The test simulates real-world scenarios such as:
A specialized (or Tubular Impact Tester) is required, which typically includes:
