1 Scope
This standard specifies a test method for determining the ability of heels of ladies’ shoes to withstand the repeated small impacts imposed by normal walking. Although intended primarily for plastics heels, the procedure is also usable for testing steel heel dowels on their own.
Note: While the test method is applicable to all types of high heels of any construction, it is particularly useful for injection-moulded plastics heels which incorporate a steel dowel reinforcement. The shape of some heels is such that they have a high fatigue resistance. It is usually considered unnecessary to test such heels for fatigue resistance.
2 Terms and definitions
For the purposes of this standard, the following term and definition apply.
fatigue resistance
resistance of a heel, under specified conditions, to repeated loading cycles.
3 Apparatus and material
3.1 The following apparatus and material shall be used:
3.2 Heel fatigue-testing apparatus, incorporating a motor-driven pendulum which can deliver blows to a test specimen assembly, each blow having an energy of 0.68 J, at the rate of one blow per second. The apparatus is clamped either on to a solid built-in bench, or on to a rigid free-standing frame anchored to the floor (see Note). An example of a suitable apparatus is shown in Figure 1.
Note: If the apparatus is not firmly mounted, there is a partial loss of energy on impact, thereby producing false results.
The apparatus shall include the following:
3.2.1 Pendulum, consisting of a circular steel bob of diameter (57±1) mm and thickness (20±1) mm, which is fixed by a circular shaft of diameter (12.5±1.0) mm to a hub on the bearing axle. The distance from the centre of the bob to the centre of the hub is (152±2) mm. The moment of the pendulum when is held horizontally is (0.68 ± 0.02) N⋅m.
