GB/T 3903.29-2008 for the performance testing of footwear outsoles. It specifies the test method for the tear force of the outsole section and the peel strength between layers, which is suitable for all types of shoe outsole materials. The standard describes the principle of two tests, introduces the required equipment such as Tensile machine, and details the preparation requirements of the sample, including how to cut and handle the outsole material. It standardizes the test operation process and clarifies the calculation and representation of the results. The standard provides a unified standard for evaluating the durability of outsole materials and the performance of interlayer bonding, helping to ensure the mass of footwear products and improve the actual performance of outsoles.
