Tensile strength test of zipper fasteners

.

Nowadays, zippers are used both for their usefulness and as a fashion accessory on clothes such as jackets, pants and skirts or even on bags and suitcases, where they play a vital role in terms of security. It is necessary to test the strength of each part of the zippers for quality control and ease of use. The test methods are described in JIS S 3015: 2019. This video measures the strength of a zipper when its bottom stop is pulled to failure using a method that complies with JIS S 3015-7.6: 2019. With the optional graphical software, it is possible to visually analyze the force transition during the entire test.
