The TQC Bend Test Conical Mandrel is a laboratory apparatus to bend coated test panels over a conical shaped mandrel in order to assess the elasticity or resistance of a coating-, paint or varnish to cracking, elongation and/or detachment from a metal test panel in accordance with ISO 6860 and ASTM D522. The conical shap of the bending area allows the deformation of the test panel and examination of the elasticity range of a coating over any diameter between 3.1 and 38 mm in one single test.
Mandrel Diameter Range: 3.1 to 38 mm
Maximum Test panel Size: 100×180 mm
Maximum Test panel Thickness: 0.8 mm
Complies with: ISO 6860, ASTM D522
