Repeat this process, increasing or decreasing the height, until the exact threshold of coating failure is identified. 4. Failure Evaluation

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

Under-cured coatings may appear artificially flexible but lack adhesion. Over-cured coatings are often brittle and prone to immediate cracking. Repeat this process, increasing or decreasing the height,
