1. Prepare the coated panel according to the manufacturer's instructions.
2. Mount the coated panel on a rigid support.
3. Position the spherical indenter on the coated panel.
4. Drop the weight onto the indenter, striking the coated panel.
5. Inspect the coated panel for signs of failure, such as cracking, flaking, or detachment.

Apparatus and Materials: The apparatus used in ASTM D2794 consists of: ASTM D2794: Standard Test Method for Resistance of

Sample Preparation: Organic coatings are applied to at least four thin (typically 24-gauge) metal panels. These samples are cured according to the manufacturer’s specifications. Prepare the coated panel according to the manufacturer's

ASTM D2794 is the globally recognized standard for evaluating the impact resistance 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.
