Footwear - Test methods for whole shoe –
Upper sole adhesion
1 Scope
This Standard describes a test method for the determination of the resistance to
separation of the upper from the outsole or to separate adjacent layers of the outsole
or to cause tear failure of the upper or the sole is measured. It also defines conditions
of ageing that can be used for production control.
It applies to all types of footwear (cementing, vulcanisation, injection moulding, etc.)
where the evaluation of sole adhesion on the upper is needed and where the upper is
continuously assembled (closed shoe).
NOTE 1. In all cases the objective should be to test the bond strength nearest to the edge of
the assembly.
NOTE 2. The test need not be carried out when the bond has been made by grindery (using,
for example, nails or screws) or stitching.
