This second edition cancels and replaces the first edition (ISO 11334-4:1999), which has been technically
revised.
The main changes are as follows:
— — the minimum requirements for stability have been removed and are replaced by requirements on
disclosure of the stability performance level for the specified direction;
— — the static strength test for the legs and separation part was added;
— Clause 6— Clause 6 on general requirements for assistive products for walking was added.

Introduction
A walking stick with three or more legs can be used when a person needs assistance for walking. It provides
more stability when walking and standing compared with other types of sticks and canes manipulated by one
arm and can thus reduce the risk of falling.

1 Scope
This document specifies requirements and test methods of walking sticks with three or more legs used as
assistive products for walking, manipulated by one arm, without accessories, unless specified in the particular
test procedure. This document also gives requirements related to safety, ergonomics, performance and
information supplied by the manufacturer, including marking and labelling.
The requirements and tests are based on every-day use of walking sticks with three or more legs as assistive
products for walking for a maximum user mass as specified by the manufacturer. This document is for walking
sticks with three or more legs specified for a user mass of no less than 35 kg.
This document is not applicable to walking sticks with three or more legs with underarm or forearm support
or with moving parts such as a universal joint.

L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d'approbation requis pour les différents types de documents ISO. Le présent document
