31、y, 02/02/2009 04:41, Uncontrolled Copy, (c) BSI ISO/DIS 7176-9 iv ISO 2008 All rights reserved 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 carri
32、ed 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. I
33、SO 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 Internati
34、onal 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 el
35、ements 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 7176-9 was prepared by Technical Committee ISO/TC 173, Assistive products for persons with disability, Subcommittee SC 1, Wheelchairs. This third edition
36、cancels and replaces the second edition (ISO 7176-9:2001), all clauses of which have been technically revised.

43、 functioning, sometimes to the extent of being dangerous. The tests specified in this document have been developed to determine whether, and to what extent, wheelchairs are vulnerable to environmental conditions. Operation is tested in conditions which simulate use in some of the wider climatic vari
44、ations experienced around the world. The wheelchair electrical system might be exposed to liquids, including salt water. Since the effects of salt water contamination are difficult to evaluate, the immunity of the system is assessed on the basis of exposure to a fresh water spray. Licensed Copy: Lon

46、 effects of changes of temperature on the basic functioning of electrically powered wheelchairs, including scooters, intended to carry one person, with a maximum speed not exceeding 15 km/h. This part of ISO 7176 does not include requirements for resistance to corrosion. 2 Normative references The f
