This standard provides a method for testing the strength of fastening components in footwear. It specifies procedures for assessing the shear strength of closures before and after repeated closing actions. The test involves applying force to the closure mechanism to determine its durability and performance under simulated use conditions. The method includes detailed instructions on sample preparation, testing equipment, and measurement techniques. It ensures consistent evaluation of the mechanical properties of fastening systems in shoe products. The standard outlines the necessary steps for conducting the test and interpreting the results. It is intended for use by manufacturers, testing laboratories, and regulatory bodies to ensure product quality and compliance with specified requirements.
