The work of preparing International Standards is normally carried out throu
17、gh 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 collabora
18、tes 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 Standar
19、ds. 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 th
20、is 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, Wheelchairs. This second edition cancels and
21、 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 wheelchairs Part 3: Determination of effec
22、tiveness of brakes Part 4: Energy consumption of electric wheelchairs and scooters for determination of theoretical distance range Part 5: Determination of dimensions, mass and manoeuvring space Part 6: Determination of maximum speed, acceleration and deceleration of electric wheelchairs Part 7: Mea

27、uction 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, which can be used to estimate the appropriaten
28、ess 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 comparable test results. The information i
29、n 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 occupants, architects and public authorities
30、, 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 purchase, the wheelchairs suitability in rel
31、ation 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, repairing or testing wheelchairs, are included
32、in Annex A. Technical Report ISO/TR 13570-11is also available, giving a simplified explanation of the different parts of ISO 7176. Technical Report, ISO/TR 13570-22, is under consideration.

33、eelchairs 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 when the wheelchair is occupied by a reference
34、 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 specifies methods for the determination of tec
35、hnical 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 determining the wheelchair longitudinal axis and wh
36、eelchair 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 wheelchairs and electrically powered wheelchairs (includ
37、ing scooters). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 7176-7,
