GB/T 21396-2022 specifies the test method for the bond strength between the upper and sole of whole-cut (closed shoe) footwear, applicable to adhesive-bonded shoes, vulcanized shoes, injection-molded or compression-molded shoes, but not applicable to footwear with nailed or stitched processes. The standard defines the preparation of specimens, environmental conditioning, and aging test conditions. It primarily utilizes instruments such as tensile testing machines, cutting equipment, and width measuring devices. Specimens are secured using different types of clamps, and the upper-sole interface is peeled at a specified speed. The test records the force-deformation curve and calculates the bond strength, while also determining the type of failure at the peeling surface. This provides a unified technical basis for quality control in footwear production and the assessment of product durability.
