Conical Mandrel Bend Tester

Conical mandrel bend tester find its application in determining the coating properties of painted /coated panels in terms of Resistance to cracking ,elongation during the test, flexibility ,adhesion when subjected to bending stresses .The tester is applied to evaluate crack resistance and detachment from the metal substrate of coated surface which are clamped in position and formed round the conical mandrel by rotation of the roller frame.

Conical Mandrel Bend Tester is applicable to determine extensibility of paint coatings on metal panels which are clamped in position and formed round the conical mandrel by rotating of the roller frame. The panels are examined to evaluate crack resistance and detachment from the metal substrate of coated surface which is coated with paint under standard condition. It complies with DIN ISO EN 6860, ASTM D 522, BS 3900 E11, DIN 53150.A graduated scale on the clamping bar indicates the mandrel diameter at which failure has occurred.
