The work of preparing International
17、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, al
18、so 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 committ
19、ees 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 poss
20、ibility 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 7176-5 was prepared by Technical Committee ISO/TC 173, Assistive products for persons with disability, Subcommittee SC 1, Wheel
21、chairs. This second edition cancels and replaces the first edition (ISO 7176-5:1986) which has been technically revised. ISO 7176 consists of the following parts, under the general title Wheelchairs: Part 1: Determination of static stability Part 2: Determination of dynamic stability of electric whe

27、E) ISO 2008 All rights reserved vii Introduction The purpose of this part of ISO 7176 is to provide technical definitions together with appropriate measurement procedures for measuring important dimensions and masses of manual wheelchairs and electrically powered wheelchairs including scooters, whic
28、h can be used to estimate the appropriateness for a given environment. A new approach is used for the pre-selection of the reference size from a wheelchair model with a range of various dimensions by introducing reference dimensions of the intended occupant. This new approach ensures repeatable and
29、comparable test results. The information in this part of ISO 7176 is intended for three main reader groups: prescribers and occupants of wheelchairs; architects and public authorities; manufacturers, wheelchair providers, clinicians and test laboratories. Features that are important to wheelchair oc
30、cupants, architects and public authorities, such as overall dimensions and the estimation of the space needed and general manoeuvrability, are contained in Clause 8. Values for the different features are disclosed in the wheelchairs specification sheet. The values can be used to determine, before pu
31、rchase, the wheelchairs suitability in relation to specific requirements and needs. The technical features of a wheelchair which are of importance to manufacturers, wheelchair providers, clinicians and test laboratories, such as items to be considered when manufacturing, setting up, adjusting, repai
32、ring or testing wheelchairs, are included in Annex A. Technical Report ISO/TR 13570-1 1is also available, giving a simplified explanation of the different parts of ISO 7176. Technical Report, ISO/TR 13570-2 2 , is under consideration. BS ISO 7176-5:2008BS ISO 7176-5:2008 INTERNATIONAL STANDARD ISO 7
33、176-5:2008(E) ISO 2008 All rights reserved 1 Wheelchairs Part 5: Determination of dimensions, mass and manoeuvring space 1 Scope This part of ISO 7176 specifies methods for the determination of wheelchair dimensions and mass. This includes specific methods for the determination of outside dimensions
34、 when the wheelchair is occupied by a reference occupant and the required manoeuvring space needed for wheelchair manoeuvres commonly carried out in daily life. This part of ISO 7176 specifies requirements for the disclosure of the dimensions and masses and contains five informative annexes. Annex A
35、 specifies methods for the determination of technical dimensions that can be important to the performance of the wheelchair. Annex B provides detailed information about pivot width and reversing width. Annex C provides detailed information about the turning diameter. Annex D provides details on dete
36、rmining the wheelchair longitudinal axis and wheelchair centre-point. Annex E provides technical guidelines and recommendations for many of the measurements specified to facilitate improved understanding, design and construction of wheelchairs. This part of ISO 7176 is applicable to manual wheelchai
37、rs and electrically powered wheelchairs (including scooters). 2 Normative references The following referenced documents are indispensable for the application of this document.
