It is ident
3、ical with ISO11334-4:1999. It supersedes BS4922:1990 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee CH/38, Walking aids, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committe
4、e any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-referenc
5、es Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The BritishStandards which implement these international or European publications may be found in
6、the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are
7、responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

22、ardization) 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
23、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 St
24、andards are drafted in accordance with the rules given in the ISO/IEC Directives, Part3. 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 least75% of the member bodies ca
25、sting a vote. International Standard ISO11334-4 was prepared by Technical Committee ISO/TC173, Technical systems and aids for disabled or handicapped persons. ISO11334 consists of the following parts, under the general title Walking aids manipulated by one arm Requirements and test methods: Part1: E
26、lbow crutches; Part4: Walking sticks with three or more legs. Annex A of this part of ISO11334 is for information only.iv blankENISO11334-4:1999 BSI 03-2000 1 1 Scope This part of ISO11334 specifies requirements and methods of testing the stability, static load capacity and fatigue of walking sticks
27、 with three or more legs and fully equipped with handle and tips. It also gives the requirements relating to safety, ergonomics, performance, marking and labelling. The requirements and tests are based on everyday usage of walking sticks with three or more legs, manufactured for a user weight (mass)
28、 of not less than35kg. This part of ISO11334 is not applicable to walking sticks with three or more legs with underarm or forearm support. NOTERecommendations further to the requirements are given inAnnex A. 2 Normative references The following normative documents contain provisions which, through r
29、eference in this text, constitute provisions of this part of ISO11334. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO11334 are encouraged to investigate the possibility of applying the
