Impact Resistance Test

This device is designed to test the impact resistance of single-layer fusion-bonded epoxy (FBE) coatings in accordance with ISO 21809-2. In this method, a one-kilogram weight with a hardened tip of 8.15 mm in diameter is dropped on the sample from a height of one meter through a scaled weight guide.

The effect of the indented tip on the impact resistance of the coating is checked with the help of the Holiday test. It is worth noting that the device has a hardened floor according to the standard.
