ISO 19956:2004规定了一种测试方法，用于测定女鞋后跟承受正常行走施加的反复小冲击的能力。虽然主要用于塑料鞋跟，但该程序也可用于单独测试钢鞋跟定位销。 虽然本试验方法适用于任何结构的所有类型的高跟鞋，但它对于包含钢销加强件的注塑塑料高跟鞋尤其有用。

ISO 19956:2004 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 plastic heels, the procedure is also usable for testing steel heel dowels on their own. While the test method is applicable to all types of high heels of any construction, it is particularly useful for injection-moulded plastic heels that incorporate a steel dowel reinforcement.
