Zipper test is mainly applicable to various types of zipper products, such as garments, bags, shoes, tents, canvas, car seats, etc. It can test the durability, tensile strength, breaking strength, corrosion resistance, heat resistance, cold resistance and other performance indexes of zippers.
Zipper test is a test method used to test the tensile strength and elongation of a material. It is based on the principle of cutting a piece of material into two halves along a pre-drawn line, and then using a fixture to fix the two halves to the upper and lower ends of the tensile machine, and then applying tension until the material breaks. By measuring the original length, fracture length, fracture area and maximum tensile force of the material, the tensile strength and elongation of the material can be calculated.
The zipper test is applicable to various types of materials, including metal, plastic, rubber, fiber, paper, etc. There are different zipper test standards for different types of materials, such as ISO 527-1, ASTM D638, GB/T 1040, etc. Zipper test can reflect the mechanical properties, deformation capacity and fracture mode of materials, which is of great significance for the research and application of materials.
