The cupping test apparatus is designed to test the elongation and deformability of lacquers and protective coatings applied to metal substrate. The test apparatus is based upon the Erichsen Principle which is used to perform a cupping test on a coated steel panel having a thickness of 0.8 – 2 mm to define the resistance of paints, varnishes and related products to cracking. This test is determined on a coated steel panel by testing to a specified depth at which coating fails.
