24、air standards the procedure presented within this standard will produce test results which permit comparison between different wheelchairs and give comparable results between different test laboratories.If a wheelchair is configured in a specific way, some clauses of ISO 7176-22 might not apply.vi I
25、SO 2014 All rights reservedBS ISO 7176-22:2014INTERNATIONAL STANDARD ISO 7176-22:2014(E)Wheelchairs Part 22: Set-up procedures1 ScopeThis part of ISO 7176 specifies a set-up procedure to be used as a part of the preparation of adjustable wheelchairs for testing. This procedure takes the manufacturer
26、s instructions into account.This part of ISO 7176 is applicable to manual wheelchairs and electric wheelchairs (including scooters) intended to provide indoor and/or outdoor mobility.NOTE Other parts of ISO 7176 may have specific requirements for the adjustment of the wheelchair. In such cases, the
27、individual part of ISO 7176 takes precedence over this part of ISO 7176.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated referen
28、ces, the latest edition of the referenced document (including any amendments) applies.ISO 7176-11, Wheelchairs Part 11: Test dummiesISO 7176-26, Wheelchairs Part 26: Vocabulary3 Terms and definitionsFor the purposes of this document, the terms and definitions given in ISO 7176-26 apply.4 Test appara
29、tus4.1 Test dummy, as specified in ISO 7176-11.4.2 Means for measuring linear dimensions up to 2 000 mm, to an accuracy of 1 mm.4.3 Means for measuring the angles of surfaces to each other and/or to vertical or horizontal, to an accuracy of 0,2.4.4 Means of measuring forces, between 25 N and 250 N t
30、o an accuracy of 5 % of the measurement4.5 Means of measuring torque, between 2 Nm and 100 Nm to an accuracy of 10 % of the measurement.4.6 Means to inflate pneumatic wheelchair tyres, up to 10 bar with an accuracy of 0,2 bar.4.7 A hard horizontal test plane, of sufficient size to support the wheelc
31、hair during testing, such that the whole surface is contained between two imaginary parallel planes 5 mm apart.NOTE The imaginary planes are intended to provide a measure of control on the flatness of the test plane. ISO 2014 All rights reserved 1BS ISO 7176-22:2014ISO 7176-22:2014(E)4.8 Means to se
32、cure the torso and thigh segment of the test dummy, so that the dummy will remain in the intended position, without deformation of the wheelchair or the dummy.It is important that the means do not prevent rotation of the hip, knee and ankle pivot.Straps made of Nylon webbing of sufficient strength m
33、ay be used.NOTE For some designs of wheelchairs, care is needed to avoid bending the tubes of the back support towards each other.4.9 Means to secure the feet of the test dummy to the foot supports, so that they will remain in the intended position, without deformation of the wheelchair or dummy.It
34、is important that the means do not affect the strength of the foot support(s).The feet of the test dummy may be clamped to the foot support(s) of the wheelchair, or holes may be drilled no greater than 8 mm in diameter and the feet bolted in position, providing the strength of the foot support(s) is
35、 not affected.5 Set-up levelsOther documents that refer to the set-up procedures specified in this document may use or modify parts of the set up procedure contained within this standard according to their own purposes. Other test standards may reference a limited number of the requirements of this
36、standard. This standard provides specific set-up information in 6.2.2 and 6.2.3. The different test standards may choose a set of setup requirements from this standard based on the three set-up levels specified in 6.2.2, 6.2.3 and in Annex C. Set-up-level 3 (from 6.2.2 and 6.2.3) shall be used if th
37、ere is no reference to another set-up level (see Annex C) or subset of requirements within a specific test standard.The Reference set-up tables contained in this standard each contain three different occupant mass groups, less than 50 kg, 50 kg to 125 kg and more than 125 kg. Use the maximum occupan
38、t mass specified by the manufacturer to determine the occupant mass group.Reference set-up tables for set-up level 1 and set-up level 2 are presented in Annex C.NOTE Guidance for wheelchair selection is presented in Annex D.6 Preparation of the test wheelchair6.1 Wheelchair equipmentWhere a particul
39、ar standard specifies equipment to be fitted to the wheelchair, use the equipment specified in that particular part. All other equipment shall be used in accordance with this subclause.Unless specified otherwise in this document or by those commissioning the tests and unless noted in the test report
40、 the wheelchair shall be complete and ready for use. It shall comprise all following components or parts, where applicable: seat, back support, arm supports, lower leg support assemblies, posterior lower leg supports, posterior foot supports, frame, wheels, hand rims, motors and drive trains, brakin
41、g system, battery sets, controllers, steering mechanisms, push handle(s), anti-tip devices, curb-climbing device.NOTE 1 Some tests can require a part of a wheelchair to be dismantled.Unless they are an integral part of the wheelchair, or necessary for the successful conduct of a test, the following
42、components or parts, including the means to connect them to the wheelchair, shall be removed: cushions,2 ISO 2014 All rights reservedBS ISO 7176-22:2014ISO 7176-22:2014(E) postural support device components such as head supports, lateral trunk supports etc., storage unit such as baskets, backpacks,
43、transfusion containers, urine collection bags and oxygen bottles.NOTE 2 A component or part that is supplied with the wheelchair and is removable but fixed with hook and loop fastener is not deemed an integral part.Where a support surface would not normally be used without a cushion (e.g. a solid pl
44、y seat support base), an appropriate cushion, such as one provided by the wheelchair manufacturer, should be fitted to the wheelchair.NOTE 3 For specific tests there are exclusions from this statement (see NOTE in 8.5).6.2 Wheelchair adjustment6.2.1 GeneralThis standard shall take precedence in sett
45、ing up a wheelchair in readiness for testing except: when a particular test standard has specific adjustment requirements, then the adjustment procedure specified in that particular standard shall be used. All other adjustments not specified in that standard shall be made in accordance with this sub
46、clause. when the manufacturer specifies particular requirements or limitations to the setup, then such variations shall be followed to the extent necessary, and such variations used shall be detailed in the test report.Set-up can be done in any order that is most practicable for each part of ISO 717
47、6.If the seat is capable of swivelling to more than one position around the vertical axis (e.g. in a scooter), adjust the seat to the forward facing position, so that the longitudinal axis of the seat is parallel to the longitudinal axis of the wheelchair with an accuracy of 2. If this position or a
48、ccuracy is not achievable set the axes as close as possible and document the variation in the test report.If the seat can be attached in a forward or rearward facing position, attach the seat to the default position specified by the manufacturer, or, where there is no such specification attach it so
49、 that the wheelchair has a rear wheel drive.In the case of an adjustable component with no defined greatest and or smallest position or dimension, the mid position shall be half way between the position fully contracted or inserted and the position fully extended or expanded.If the wheelchair has pneumatic tyres, inflate them to the pressure recommended by the wheelchair manufacturer. If a pressure range is given, inflate to the highest pressure in the range. If there is no recommendation for inflation pressure from
