Mandrel set ASTM for SP1822 Bend Test – SP1833
The TQC Bend Test Cylindrical Mandrels consists of 14 mandrels for the TQC Bend Test Cylindrical, a bend test for determining the elasticity of coatings in accordance with ISO 1519. A test panel (max. size 150x100mm) is bent over a cylindrical mandrel, the smaller the diameter of the mandrel, the greater the tension on the coating. The coating on the test panel is then checked for cracks or damage.
