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.
