GB/T 3903.6-2024 specifies test methods for evaluating the slip resistance of whole footwear or outsoles, applicable to various types of footwear and sole materials without special structures such as studs or metal spikes. The core evaluation is based on measuring the coefficient of friction to assess slip resistance. The standard includes tests on dry, wet, and newly added frost/ice interfaces, and specifies vertical load requirements corresponding to different shoe sizes. The testing requires a slip resistance tester (with controllable vertical pressure and sliding speed), wedge blocks, frost/ice interface preparation instruments, S96 standard rubber, various test interfaces, and a friction measurement device with an accuracy of 0.1 N to ensure precise test data. This provides a unified technical basis for quality control and safety performance evaluation of footwear products.
