Full title and description

St ISO 22650-2018 — Footwear — Test methods for whole shoe — Heel attachment. This international standard specifies laboratory test methods to determine heel attachment properties of whole footwear, applying primarily to women's medium and high heeled shoes; it measures backpart rigidity during simulated walking, permanent deformation under a larger rearward force, and the force required to detach the heel.

Abstract

ISO 22650:2018 (second edition) defines apparatus, sampling and conditioning, test procedures and result expression for assessing heel attachment. Tests use a tensile-testing machine (to ISO 7500-1 accuracy class B) with purpose-designed heel fixtures and report rigidity (under 200 N), permanent set (after 400 N), and heel detachment force in newtons. The document replaces ISO 22650:2002 and includes requirements for test reporting.

Scope

Specifies a laboratory method for determination of heel attachment of footwear, applicable to women's medium and high-heeled footwear. The standard addresses three related wear properties: rigidity of the shoe backpart during simulated walking, permanent deformation of the backpart after a larger rearward force, and the maximum force required to detach the heel. Normative references include ISO 7500-1 for calibration and verification of the testing machine.

Key topics and requirements

• Definition of terms: heel attachment strength, rigidity, permanent deformation (expressed in newtons and millimetres as applicable).
• Apparatus and materials: tensile-testing machine complying with ISO 7500-1 (class B accuracy), low-inertia machine with autographic force recording and heel-clamping fixtures (distinct designs for chunky vs. slender heels).
• Sampling and conditioning procedures for whole shoes prior to testing.
• Test method and procedure: stepwise loading to specified forces (e.g., 200 N for rigidity measurement; 400 N for permanent deformation) and a heel-detachment test to measure maximum force required to separate the heel.
• Expression of results and required contents of the test report (including test conditions, specimen identification, numerical results and any deviations).
• Normative references and traceability requirements for force-measuring systems and calibration (referencing ISO 7500-1).

Technical content and procedural parameters summarized from the published standard and its catalogue description.

Typical use and users

Used by footwear manufacturers, product development and quality assurance teams, independent testing laboratories, conformity assessment bodies, component suppliers (heels and heel fittings), regulatory/market surveillance authorities and import/export compliance laboratories to verify heel attachment performance and report reproducible, comparable test results. The standard supports product specifications, supplier acceptance testing and in-house quality controls.

Related standards

ISO 22650:2018 revises ISO 22650:2002 (previous edition). Normative and related references include ISO 7500-1 (calibration/verification of tension/compression testing machines). Other footwear test-method standards covering heels, shanks, insoles and outsole tests (e.g., ISO 19956, ISO 19957, ISO 22651, ISO 22653 and various ISO 2086x series test methods) are commonly used alongside ISO 22650 for comprehensive footwear testing programs.

FAQ

Q: What is this standard?

A: ISO 22650:2018 is an international test-method standard titled "Footwear — Test methods for whole shoe — Heel attachment" that specifies laboratory procedures to evaluate heel attachment properties for women's medium and high-heeled shoes.

Q: What does it cover?

A: It covers apparatus requirements, sampling and conditioning, detailed test procedures (including loading sequences), measurement of backpart rigidity and permanent deformation, heel detachment force measurement and the required test reporting. ISO 7500-1 is cited as a normative reference for force-measuring accuracy.

Q: Who typically uses it?

A: Footwear manufacturers, design and QA teams, independent testing laboratories, conformity assessment and regulatory bodies, and component suppliers use this standard to specify, verify and document heel-attachment performance.

Q: Is it current or superseded?

A: ISO 22650:2018 is the second edition (published 14 March 2018) and replaces ISO 22650:2002. Catalogue maintenance records show the standard as published and recorded in ISO’s catalogue; the standard’s maintenance stage was noted as confirmed in maintenance metadata. There is no indication of a newer replacement published as of the catalogue metadata.

Q: Is it part of a series?

A: ISO 22650 is a single-method standard focused on heel attachment; it is part of the broader family of footwear test-method standards (ISO/TC 216 output) but is not numbered as a multi-part series. Related footwear test standards cover other whole-shoe and component tests.

Q: What are the key keywords?

A: Keywords include footwear, heel attachment, heel detachment force, backpart rigidity, permanent deformation, tensile-testing, test method, ISO 7500-1, ISO/TC 216.
