Test Method: SATRA TM87
Fatigue test for rigid sole units and shoe bottoms
January 1998
SCOPE
This method is intended to reproduce the effect of the repeated forces applied to sole units or shoe bottoms in normal walking. The method is applicable to rigid through bottom units – often called clog units or through platform units – made from rigid plastic, rigid polyurethane or wood, and to complete shoe bottoms containing these units.
PRINCIPLE
The test specimen is clamped across the forepart and forces are applied to the heel alternately from above and below, as in wear. For the testing of women’s units under normal conditions, the nominal force is 50 N, and for men’s units 120 N. In addition, an accelerated test can be carried out on the most rigid women’s units using a force of 100 N. The test specimen is subjected to a given number of loading cycles and the resulting damage is recorded.
