Shoe Abrasion Tester
The Shoe Abrasion Tester is designed to evaluate the wear resistance of shoe soles and sole pieces. The instrument uses a rotary grinding head that applies a controlled vertical load on the sample while rotating at a standardized speed. After testing, the wear length or mass loss of the sample is measured to assess its durability, providing quantitative data for quality control, product development, and standard compliance.
Application
This tester is suitable for:
(1) Footwear Manufacturers: To verify the durability of finished soles and sole materials.
(2) Quality Inspection Laboratories: For conformity testing according to national standards.
(3) R&D Centers: To evaluate new sole materials or designs under controlled wear conditions.
(4) Material Testing: For evaluating abrasion resistance of rubber, thermoplastic, or composite sole materials.
Standards
(1) GB/T 3903.2-2017 – Testing of shoe wear resistance
(2) QB/T 4329-2012 – Shoe sole abrasion testing
(3) Applicable international or regional standards for abrasion resistance upon request
