Description (English):

La présente partie de l'ISO 11334 spécifie les exigences et les méthodes d'essai relatives à la stabilité, à la résistance à la charge statique et à la fatigue des aides à la marche avec au moins trois jambes ou plus, équipées d'une poignée et d'un embout. Elle spécifie également les exigences en matière de sécurité, d'ergonomie, de performances, de marquage et d'étiquetage. Les essais et les exigences sont basés sur un usage quotidien des cannes de marche avec au moins trois jambes ou plus, fabriquées pour un utilisateur ayant un poids (une masse) de 35 kg minimum. La présente partie de l'ISO 11334 n'est pas applicable aux cannes de marche avec au moins trois jambes ou plus avec appui d'avant-bras ou appui axillaire. NOTE L'annexe A contient des recommandations relatives aux exigences contenues dans la présente partie de l'ISO 11334.

Abstract

Overview

ISO 11334-4:1999, published by ISO (International Organization for Standardization), defines requirements and test methods for walking aids manipulated by one arm - specifically walking sticks with three or more legs (tripods, quadropods, five‑point walkers). The standard addresses safety, ergonomics, stability, mechanical strength, durability, marking and labelling, and test reporting for devices manufactured for users with a mass of not less than 35 kg. It is part of the ISO 11334 series developed by ISO/TC 173 (technical systems and aids for disabled or handicapped persons).

Key topics and technical requirements

Scope & classification
- Applies to walking sticks with 3+ legs; excludes underarm or forearm support designs.
- Standard user weights: 100 kg (adult), 35 kg (child).
Handle and handgrip
- Handgrip width: 25–50 mm (except anatomic grips).
- Handgrip must be replaceable or easy to clean; recommended non‑absorbent materials and slip‑resistant shape.
Legs and tips
- Tip contact area minimum diameter: 35 mm.
- Tips must prevent leg piercing and be replaceable and wear‑resistant.
Adjusting devices & dimensions
- Height adjustment must not work loose; telescoping members must have easy running fit.
- Minimum vertical clearance at centre of base (at minimum height): 120 mm.
Stability requirements
- Inwards stability: tilt angle at tipping point ≥ 2°.
- Outwards stability: tilt angle at tipping point ≥ 5° for three‑leg and 7.5° for four‑or‑more legs.
Mechanical strength & test loads
- Separation test: pull force 500 N.
- Static loading test: nominal 1000 N (or 10 N per kg of declared max user weight), minimum 350 N.
- Fatigue test: cyclic load 450 N (or 4.5 N per kg), minimum 157.5 N, 200,000 cycles at ≤1 Hz.
- Tests performed at ambient ~21 °C; samples tested at maximum height unless stated otherwise.
Marking & labelling
- Must include maximum user weight, manufacturer ID, model, month/year of manufacture, and max extension marking.
Test report
- Requirements for documented test reports and optional Annex A recommendations (design and durability guidance).

Applications and users

This standard is essential for:

Manufacturers and product designers of multi‑leg walking sticks (tripod/quadropod canes)
Test laboratories performing conformity, safety, and durability testing
Regulatory and procurement bodies specifying safety requirements
Clinicians, occupational therapists and assistive‑technology assessors advising on safe assistive devices
Quality and compliance teams ensuring products meet ergonomic and mechanical performance benchmarks

Keywords: ISO 11334-4, walking sticks with three or more legs, walking aids, stability tests, static loading, fatigue test, ergonomic requirements, marking and labelling.
