GB/T 3903.25-2008 in English

《GB/T 3903.25-2008鞋类 整鞋试验方法 鞋跟结合强度》由TC305（全国制鞋标准化技术委员会）归口，主管部门为中国轻工业联合会。
GB/T 3903的本部分规定了鞋类的鞋跟结合强度的测定方法，可取得三个相关的穿用性能：--正常行走时鞋后部的硬度；--向鞋跟施加力而引起鞋后部的永久性形变；--分离鞋跟所需要的力。本部分适用于中高跟女鞋。

1 Scope

This part of GB/T 3903 specifies a method for the determination of the heel attachment of 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.

This part applies to woman's medium and high heeled footwear.
