Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by China National Light Industry Council. This Standard is under the jurisdiction of the National Technical Committee on Leather of Standardization Administration of China (SAC/TC 252). This standard is issued for the first time. Leather products — Test method of flexing resistance for belt 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. 3.1.2 Load-bearing device, connected with the specimen holder moving in the left and right direction. The load-bearing weight can be loaded as needed. When the weight is not loaded, the specimen holder is not subjected to force, and can move freely in the left and right direction. 3.1.3 Driving device, connected with the specimen holder moving in the front and rear direction, and driving specimen holder makes a reciprocating motion with a stroke of (55±3) mm and adjustable frequency, so that the two specimen holders make a reciprocating flexing motion perpendicular to the installation direction of the specimen. 3.1.4 Counter, for recording the number of flexing resistance. 3.1.5 Control device, when the specimen is abnormal during the test, it has an automatic stop function, and automatically records the number of flexing resistance. Figure 1 Flexing resistance tester 3.2 Bending force tester It consists of a dynamometer and a bending block. The accuracy of the dynamometer is 0.1 N, as shown in Figure 2. Figure 2 Bending force tester 4 Preparation of specimen Cut a specimen with the length equal to the sum of the clamping length of the two specimen holders and the initial gauge and of no less than 100 mm, place it in the environment at a temperature of 18℃ to 25℃ for not less than 1 h; the specimen shall not be squeezed during the period of its placement. The specimen shall be tested in this environment or in other environments within 0.5 h.
