Testing Principle:
A rotating grinding wheel is pressed vertically against the specimen. An abrasion test is conducted on the specimen under specific conditions, and the length of the resulting abrasion mark is measured to indicate the specimen's wear resistance.
Test Procedure:
1. Prior to testing, identify the specific test location. If the outsole consists of a single material, testing may be performed on any flat area of the outsole. If the load-bearing areas of the outsole that make contact with the ground—such as the forefoot flex zone and the heel strike zone during a wearer's standing posture—are composed of two or more different materials, the abrasion resistance of each individual material must be tested.
2.The test surface of the sample should be flat. If necessary, the surface of the sole pattern should be polished. The polishing depth should be just enough to remove the pattern.
3. The specimen shall be conditioned at room temperature for a minimum of 4 hours.
4. Ensure that all components of the testing machine are properly adjusted and functioning normally; prior to each test run, allow the abrasion wheel to run idle for 5 minutes.
