Astm D2794 - Pdf
To perform the test according to the ASTM D2794 guidelines, a laboratory must possess: A standard impact tester with a vertical guide tube. A set of weights (usually 1 lb, 2 lb, or 4 lb). An indenter with a spherical head. A die or anvil that supports the test panel. A magnifying glass (usually 10x) for post-test inspection. Applications Across Industries
ASTM D2794 is a standard test method developed by the American Society for Testing and Materials (ASTM) that provides a procedure for evaluating the impact resistance of paints and coatings applied to metal substrates. The test method is designed to simulate the types of impacts that coatings may experience during their service life, such as those caused by hail, tools, or other objects. astm d2794 pdf
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. To perform the test according to the ASTM
For manufacturers and quality control labs, the standard for measuring this toughness is . A die or anvil that supports the test panel
To fully appreciate a search for an "ASTM D2794 PDF," you must understand the mechanics of the test. The apparatus is often called a (named after the original inventor).
Originally developed for the automotive and appliance industries, ASTM D2794 has become a universal quality control tool. It helps manufacturers predict how a coating will behave during fabrication (bending, stamping) and in-service life (accidental impacts).
