GB/T 3903.25-2021 Footwear—Test methods for whole shoe—Heel attachment English
1 Scope
This document specifies a method for the determination of the heel attachment of footwear.
It applies to woman's medium and high heeled footwear.
This test method measures three related wear properties:
——The rigidity of the shoe backpart during normal walking;
——The amount of permanent deformation of the backpart caused by a fairly large force applied to the heel in a backward direction;
——The force required to detach the heel.
