Footwear - Test methods for whole shoe - Heel attachment (ISO/DIS 22650: 2016)

This draft 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.

Overview

oSIST prEN ISO 22650:2016 sets out standardized test methods to evaluate the heel attachment strength of whole footwear, specifically focusing on women’s medium and high-heeled shoes. Developed under the collaboration between ISO and CEN, this draft international standard enables manufacturers, laboratories, and quality assurance professionals to assess crucial safety and durability aspects of heeled footwear. Accurate testing of heel rigidity, deformation, and attachment strength is vital to ensuring product performance and minimizing risks of heel detachment during wear.

Key Topics

• Heel Attachment Testing: The standard provides a test protocol to assess the structural integrity of the heel within whole shoes.

  • Rigidity: Measures the deformation of the shoe’s backpart under normal walking stress.
  • Permanent Deformation: Assesses how much the backpart deforms when subjected to a larger backward force.
  • Detachment Force: Determines the maximum force required to separate the heel from the shoe.

• Test Equipment: Specifies the use of a tensile testing machine complying with ISO 7500-1 and special clamps or devices to accommodate both chunky and slender heels.

• Sampling and Conditioning: Outlines sample preparation, including guidelines for modifying the forepart to fit testing equipment, and the minimum number of samples required.

• Reporting Requirements: Defines essential parameters for test reports, such as heel attachment strength, rigidity, deformation, sample descriptions, deviations, and testing date.

Applications

oSIST prEN ISO 22650:2016 has broad practical applications in the footwear industry:

• Quality Control: Manufacturers can use this standard to verify that footwear meets essential safety and performance benchmarks before going to market.
• Product Development: Footwear designers and engineers apply these test methods to select materials and construction techniques that enhance heel durability.
• Compliance and Certification: Brands and suppliers rely on standardized testing to demonstrate conformance to customer specifications and international regulations.
• Laboratory Testing: Independent and in-house testing laboratories utilize this method to provide consistent, reproducible results regarding heel attachment in women’s shoes.
• Market Surveillance: Regulatory bodies may employ these tests to identify non-compliant products and safeguard consumers against premature footwear failures.

By establishing a uniform approach to evaluating heel attachment, this standard helps reduce the risk of injury due to heel detachment and supports consumer confidence in product quality.

Related Standards

To ensure comprehensive footwear testing and standardization, oSIST prEN ISO 22650:2016 references or complements several other key international standards:

• ISO 7500-1: Metallic materials - Verification of the force measuring systems of tensile testing machines, ensuring accurate force measurement.
• ISO 18454: Footwear - Standard atmospheres for conditioning and testing of footwear and components.
• ISO/TC 216: Footwear - Technical Committee responsible for the development of footwear standards.
• EN Footwear Standards: European footwear test methods for various properties including slip resistance, impact absorption, and upper-to-sole bond strength.

Adopting oSIST prEN ISO 22650:2016, together with related standards, supports robust product testing and conformity throughout the footwear supply chain.

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.

a backward direction
 the force required to detach the heel.

ISO/WD 22650
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.
