About This Product
A crackness test checks whether the grain surface of leather cracks when it is bent. The test piece is clamped at one end, and the mandrel and the roller are brought against opposite faces of the middle of the piece, so the leather is bent around the mandrel. Mandrels of different diameters give different degrees of bending. The grain surface is then examined for cracks and the results are compared between samples. The Crackness Tester (Apparatus) can be supplied and exported to buyers in Madagascar, Uzbekistan, Chile, Slovenia and Latvia.
