Used to test the resistance to repeated flexing damage of coated fabrics. This machine is the S childknecht test method. DRK516C fabric flexing tester is used to test the resistance to repeated flexing damage of coated fabrics. This machine is the S childknecht test method. Standards compliant: GB/T 12586-2003 Rubber or plastic coated fabrics-Determination of flexural damage resistance (Method C fold flexion method), ISO 7854, BS 3424:Part9 Test principle: The long coated fabric sample strip is stitched into a cylindrical shape. Place the coated fabric cylinder between two discs and fix it in position, one of which reciprocates about 90° on its axis to twist the specimen, and the other disc reciprocates along its axis to compress Sample. After a certain number of twists and compressions or until the sample is obviously damaged, the flexural damage resistance of the sample can be evaluated. Technical parameter: 1.
