1 Scope
This standard specifies the principle, devices, test method and test report of the flexing resistance for leather belt products.
This standard applies to waistbands, braces, luggage soft handles and other belt products.
2 Principle
Select the appropriate initial gauge and load-bearing weight based on the bending force of the specimen, reciprocate the flexing resistance at a certain frequency to inspect the quality of the waistbands, braces, luggage soft handles and other belt products.
3 Devices
3.1 Flexing resistance tester
It shall include the components specified in Subclause 3.1.1~3.1.5, as shown in Figure 1.
3.1.1 Specimen fixing device, consisting of a pair of specimen holders, one of which can move in the left and right direction, and the other can move in the front and rear direction. The initial positions of the two specimen holders are in a straight line.
