Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 22650 was prepared by Technical Committee ISO/TC 216, Footwear, Subcommittee SC , and by
Technical Committee CEN/TC 309, Footwear in collaboration.

WORKING DRAFT ISO/WD 22650
Footwear — Test methods for whole shoe — Heel attachment
1 Scope
This standard 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.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 7500-1 Metallic materials – Tensile testing – Part 2: Verification of the force measuring system of the
tensile testing machines.
ISO 18454 Footwear – Standard atmospheres for conditioning and testing of footwear and components
for footwear.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
heel attachment strength
the maximum force in newtons measured under these testing condition required to detach the heel from the
sole/insole assembly
3.2
rigidity
back part deformation measured under these test conditions under a force of 200 N
3.3
permanent deformation
the permanent set of the backpart measured under these test conditions at a force of 400 N

4 Apparatus and material
The following apparatus and material shall be used:
4.1 Tensile machine
The tensile-testing machine shall comply with the requirement of ISO 7500-1 to an accuracy corresponding to
class B, with a constant rate of traverse of 100 mm/min ± 10 mm/min.
A low-inertia machine having autographic force recording facilities is essential.
4.2 Devices for attaching the shoe heel
Devices for attaching the shoe heel near its tip to the upper clamp attachment of the tensile testing machine so
that the heel can pivot freely during the test. Different designs are needed for chunky and slender heels as
described below.
4.2.1 Device for chunky heels
A suitable device is shown in figure 1. The 6 mm diameter rod G is removable and may be inserted through a
6 mm or 7 mm diameter pre-drilled hole in the heel as shown in figure 3. The block H at the opposite end of the
device has a 13 mm diameter hole which enables it to be fitted directly to a tensile testing machine in place of the
top clamp. Alternatively, where a tensile testing machine is being used which does not have removable clamps,
the block H would be replaced by a part which can be gripped in the machine clamps.
Figure 1 – Type 1 device for providing the connecting link between
the tensile testing machine and the heel stem
NOTE Rod G can be inserted through the hole drilled in chunky heels or removed and replaced by the clamp shown in
figure 2 for testing slender heels.
4.2.2 Clamp for slender heels
The device shown in figure 2 consists of a U-shaped part A which clamps against the front face of the heel (the
heel breast), and parts B and C which clamp against the curved back of the heel.
The distance between parts B and A is adjustable to suit the heel tip dimensions, using the four screws D. Part C
pivots in the two parts B, to allow for the tapering of most slender heels near their tip. The two screws E have
pointed ends to dig into the heel and so prevent the clamp slipping. The clamp is 20 mm deep. At each end of part
A are two spigots F of diameter 6 mm whose centres are 10 mm above the clamping face of part A and 10 mm
from each edge. These spigots enable the clamp to be fitted into the connecting device shown in Figure 2 in place
of rod G.
