BS 5131-5.7:1978

This standard BS 5131-5.7:1978 Methods of test for footwear and footwear materials. Testing of complete footwear is classified in these ICS categories:

• 61.060 Footwear

This Section describes a test that reproduces the effect of the repeated forces applied to the unit in normal walking, which may eventually produce cracking or complete fracture. The magnitude and direction of the forces used in the test are based on measurements made in wear on shoes containing rigid units. This test is applicable to rigid through bottom units (often called clog units or through platform units) made from rigid plastics, rigid polyurethane, or wood, and to complete shoe bottoms containing these units, i.e. with the insole and outsole left on. It is also suitable for testing complete bottoms containing cork or semi-rigid PVC units, but not for testing these units on their own. It is not applicable to more flexible units because they bend too much to allow the full fatigue force to be applied. For these more flexible units the test described in Section 5.8 of this standard is recommended.

NOTE Section 5.7 is based on SATRA¹⁾ Physical test method PM87.
