BEND TEST CONICAL MANDRELbendingbending test

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.

TQC Bend Test Conical Mandrel
Mandrel Diameter Range: 3.1 to 38 mm
Maximum Test panel Size: 100x180 mm
Maximum Test panel Thickness: 0.8 mm
Complies with: ISO 6860, ASTM D522




The TQC Cylindrical Bend Test is used to determine the elasticity adhesion and elongation of paint on sheet metal in accordance with ISO 1519. A test panel (max. size 150 x 100 mm) is bent over a cylindrical mandrel. The smaller the diameter of the mandrel, the larger the tension on the coating. The test panel is then checked for cracks or damage in the coating.

The luxurious desktop holder with 14 mandrels can also be wall mounted.Bend test
