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
