Assistive products for walking manipulated by one arm - Requirements and test methods - Part 1: Elbow crutches (ISO 11334-1:2007)

This part of ISO 11334 specifies requirements and test methods for elbow crutches fully equipped with handgrip and tip. The methods specify testing of separation, static load capacity, fatigue and resistance to low temperature embrittlement. This part of ISO 11334 also gives the requirements relating to safety, ergonomics, performance, and information to be supplied by the manufacturer, including marking and labelling. The requirements and tests are based on every-day usage of elbow crutches when performing the throughswing gait, for a maximum user mass as specified by the manufacturer. This part of ISO 11334 is applicable to elbow crutches specified for a user mass of not less than 35 kg. Requirements and test methods for friction of rubber tips against the walking surface are dealt with separately.

Gehhilfen für einarmige Handhabung - Anforderungen und Prüfverfahren - Teil 1: Unterarmgehstützen (ISO 11334-1:2007)

Dieser Teil von ISO 11334 legt Anforderungen und Prüfverfahren für Unterarmgehstützen fest, die mit Griff und Stockpuffer ausgestattet sind. Die Verfahren legen die Prüfung der Trennung, statischen Beanspruch¬barkeit, Ermüdung und Beständigkeit gegen Versprödung bei niedrigen Temperaturen fest. Dieser Teil von ISO 11334 gibt auch die Anforderungen an Sicherheit, Ergonomie, Leistungsfähigkeit und vom Hersteller zu liefernde Informationen, einschließlich Kennzeichnung und Aufschriften an.
Die Anforderungen und Prüfungen beruhen auf dem alltäglichen Gebrauch von Unterarmgehstützen bei der Ausführung des durchschwingenden Ganges bei einer vom Hersteller festgelegten Höchstmasse des Benutzers. Dieser Teil von ISO 11334 gilt für Unterarmgehstützen, die für eine Masse des Benutzers nicht unter 35 kg bestimmt sind.
Anforderungen und Prüfverfahren für die Reibung der Gummipuffer gegenüber der Gehfläche werden gesondert behandelt.
ANMERKUNG   Die Empfehlungen im Anhang A ergänzen die Anforderungen dieses Teil von ISO 11334.

Produits d'assistance a la marche manipulés avec un bras - Exigences et méthodes d'essai - Partie 1: Cannes a appui antibrachial (ISO 11334-1:2007)

L'ISO 11334-1:2007 spécifie les exigences et les méthodes d'essai relatives aux cannes à appui antébrachial équipées d'une poignée antiglisse et d'un embout. Les méthodes spécifient les essais de séparation, de résistance à la charge statique, de résistance à la fatigue et de résistance à la fragilisation à basse température.
L'ISO 11334-1:2007 fixe également les exigences en matière de sécurité, d'ergonomie, de performances et d'informations à fournir par le fabricant, y compris le marquage et l'étiquetage.
Les exigences et les essais sont fondés sur un emploi quotidien des cannes à appui antébrachial dans des conditions de marche pendulaire pour un poids maximal de l'utilisateur spécifié par le fabricant. L'ISO 11334‑1:2007 s'applique aux cannes à appui antébrachial spécifiées pour un poids de l'utilisateur au moins égal à 35 kg.
Les exigences et les méthodes d'essai relatives au frottement des embouts en caoutchouc contre la surface de marche seront traitées séparément.

ISO 11334-1:2007(E)
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 11334-1 was prepared by Technical Committee ISO/TC 173, Assistive products for persons with disability.
This second edition cancels and replaces the first edition (ISO 11334-1:1994), which has been technically
revised.
ISO 11334 consists of the following parts, under the general title Assistive products for walking manipulated
by one arm — Requirements and test methods:
⎯ Part 1: Elbow crutches
⎯ Part 4: Walking sticks with three or more legs
