This tester is designed to test the impact endurance of coating material. Put the coating face of specimen upwards, and connect it with the specified radius Impact Head. Then use a certain weight to impact the Impact Head from a fixed height. Check the damage or deformation of coating.
To do an impacting test for painting and coating materials is to use an impacting head with various round angles to touch the specimen at the start, and then a selected weight free dropping from a certain height to hit the impacting head to impact the specimen. Running the same way to test three more specimens, leave them to stand for an hour, and then watch if there is a crack on the painting.
It is compatible with ASTM D 2794, JISK 5400, and CNS 10756.
