ISO 4643 230344 SATRA TM25 Shoe Surface Leather Tensile Testing Machine EN Compression Resistance Tester
Instrument Introduction
The test sample is placed on the VAMP flexure resistance testing machine. After conducting flexure tests at a certain frequency using the VAMP flexure resistance testing machine, the changes on the surface of the test sample are observed. The flexure resistance performance of the test material is evaluated based on whether wrinkles and fractures appear on the surface and their severity. The shoe upper stretch testing machine is a testing machine suitable for repeated stretching and fast movements, simulating the compression, stretching, and flexure of the shoe upper during wearing and walking.
Compliant with standards
Standards such as GB/T 20991-2007, EN ISO 230344-2012, SATRA TM25, and ISO 4643.
Application Industry
After the test, inspect the creases, folds or damages on the sample to use as a reference for selecting the shoe upper material.
