ISO 19957:2021 Scope
This document specifies a test method for measuring the force required to pull a single heel pin out of a heel. This test method is used both to measure the heel pin holding strength of heel materials by using a standard heel pin and a method of insertion, and to assess the heel nailing of commercial production.
This test method is applicable to testing plastics and wooden heels for women’s footwear. Heels composed of layers of fibreboard or leather and low plastics heels for men’s footwear cannot be tested by this method.
