3 Principle
In the process of wearing rubber shoes and sports shoes, under the action of pressure and friction, the outsole of rubber shoes and sports shoes will slip from the ground, the coloured sole materials of rubber shoes and sports shoes will transfer on the ground and leave markings. In this test method, the test piece is placed on the surface of a specified white or black PU standard plate and perform a reciprocating test at specified pressure, number of times, stroke and frequency. After reaching the specified number of tests, observe whether there are marks of test piece on the standard plate, adopt gray scale for color change for making comparison and then assess the degree of marking.
