The ASTM D2794 procedure uses a falling-weight apparatus to induce a controlled impact on a coated panel.
ASTM D2794 is the globally recognized standard for evaluating the of organic coatings. This test method specifically measures a coating's ability to resist cracking or peeling when subjected to rapid deformation. It is a critical benchmark for manufacturers in the automotive, construction, and industrial sectors to ensure their products can withstand real-world mechanical stresses. Core Objectives of ASTM D2794
The primary goal of this standard is to predict how well a coating will hold up during its service life when hit by tools, debris, or other heavy objects. The test determines: astm d2794 pdf
Once a crack is identified, multiple tests are conducted at that height to confirm the results. ASTM D2794: Impact Resistance Test Explained
The panel is placed in the tester, either with the coated side up ( direct impact ) or down ( reverse impact ). The ASTM D2794 procedure uses a falling-weight apparatus
A standard weight (often 2 lb or 4 lb) is dropped through a guide tube from a known height onto an indenter.
How much the coating can stretch with the substrate without breaking. It is a critical benchmark for manufacturers in
Organic coatings are applied to at least four thin (typically 24-gauge) metal panels. These samples are cured according to the manufacturer’s specifications.
