3、0 580 32460 5 National foreword This British Standard is the English language version of EN ISO 11334-4:1999. It is identical with ISO 11334-4:1999. It supersedes BS 4922:1990 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee CH/38, Walking aids, which
4、has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them i
5、n the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their correspondin
6、g European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue

25、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
26、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
27、andards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. 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
28、 casting a vote. International Standard ISO 11334-4 was prepared by Technical Committee ISO/TC 173, Technical systems and aids for disabled or handicapped persons. ISO 11334 consists of the following parts, under the general title Walking aids manipulated by one arm Requirements and test methods: Pa
