GB/T 3903.25-2021 specifies the test method for heel bond strength of women's shoes with heels and high heels, primarily determining three core indicators: the rigidity of the rear part of the shoe, permanent deformation, and the force required for heel separation. The standard clearly defines the requirements for test equipment and procedures, with the core equipment being a tensile testing machine that meets precision requirements, equipped with specialized fixtures for thick and thin heels, as well as a distance measuring instrument. A tensile force is applied at a speed of 100 mm/min. Through tensile testing after fixing the shoe body and heel, the force values and deformation data are automatically recorded, providing a unified basis for quality control of the structural stability and wearing safety of footwear products.
