Cupping test according to DIN EN ISO 1520

The cupping test is used to test the resistance of a coating to cracking or detachment from a metallic substrate that is gradually deformed by deepening. A hemispherical die is pressed against the test plate until a crack forms, the coating detaches from the metallic substrate, or the required cupping depth has been achieved.
