The punch strikes the coated side of the panel directly, creating a concave indentation. astm d2794 pdf

Do you require compliance with ?

Organic coatings protect surfaces from corrosion, weathering, and mechanical wear. However, in real-world applications, these coatings often face sudden, high-velocity impacts. Whether it is a stone chipping an automotive fender or a tool dropping on an industrial pipeline, a coating must resist cracking and delamination under rapid deformation. By adhering strictly to the guidelines established within

Release the weight so it falls freely onto the indenter, which strikes the panel. 4. Increasing Impact Energy

Once the weight has deformed the panel, the impacted area must be meticulously inspected for failure. According to the standard, failure is defined as the appearance of cracks visible to the naked eye or under magnification, or the total delamination of the film.

Alternatively, pressure-sensitive adhesive tape can be applied to the impact zone and pulled off sharply to test for loss of adhesion. 5. Calculations and Reporting Results
