The weight strikes the uncoated side of the panel, causing the coating to stretch outward (extrusion). Standard Test Procedure
The test involves applying a test solution (either sulfuric acid or sodium hydroxide) to a coated panel and then observing the coating for signs of deterioration, such as blistering, cracking, or loss of adhesion. The test solution is applied to the coated surface using a filter paper pad that is saturated with the test solution. astm d2794 pdf
In a reverse impact test, the weight strikes the of the panel directly. This forces the coating outward. The weight strikes the uncoated side of the
, is a cornerstone of materials science and quality control in the coatings industry. This standard provides a rigorous procedure for assessing how well organic coatings—such as paints, varnishes, and powder coatings—withstand sudden mechanical stress. By quantifying a coating's ability to resist cracking or delamination under impact, ASTM D2794 enables manufacturers in the automotive, construction, and aerospace sectors to ensure product longevity and safety. Micom Laboratories Inc. Technical Procedure and Methodology In a reverse impact test, the weight strikes
The precision and bias of the test method described in ASTM D2794 have been evaluated through interlaboratory testing. The results of this testing have shown that the test method is reliable and reproducible.
