Astm D2794 Pdf

ASTM D2794 is a standard test method developed by the American Society for Testing and Materials (ASTM) that covers the determination of the resistance of organic coatings to surface deterioration caused by acidic and alkaline chemicals. The test is often referred to as the "Sulfuric Acid Resistance Test" or the "Alkaline Resistance Test," depending on the specific exposure conditions used.

In a reverse impact test, the weight strikes the of the panel directly. This forces the coating outward. astm d2794 pdf

Typically 24 to 48 inches long with graduations in inch-pounds. ASTM D2794 is a standard test method developed

Organic coatings are applied to at least four thin (typically 24-gauge) metal panels. These samples are cured according to the manufacturer’s specifications. This forces the coating outward

ASTM D2794 remains the gold standard for evaluating the toughness of organic coatings. Whether you are formulating a new industrial epoxy or quality-checking a batch of automotive paint, understanding the difference between direct and reverse impact—and how to properly quantify the results—is essential for ensuring product longevity.

The coated panels are then placed in a controlled environment, and the effects of the test solution on the coating are evaluated over a specified period. The test can be conducted at room temperature or at elevated temperatures.
