GB/T 41082.2-2023 Wheelchairs - Part 2: Typical values and recommended limits of dimensions, mass and manoeuvring space as determined in GB/Z 18029.5
1 Scope
This document lists the typical values and recommended limits of the dimensions obtained from measurements taken in accordance with ISO 7176-5. This document lists the typical values and recommended limits of the important wheelchair dimensions (ready for occupation and folded or dismantled), space for pivoting or reversing between limiting walls and some dimensions worthwhile to estimate usability of the wheelchair as well as determination of the mass of the wheelchair. It is intended for use of prescribers, clinicians, wheelchair occupants or manufacturers.
This document lists the typical values and recommended limits of the dimensions when the wheelchair is occupied and some operating areas when performing special tasks encountered in every day’s life.
This document lists the typical values and recommended limits of the technical dimensions critical to the performance of the wheelchair. This document applies to manual wheelchairs and electrically powered wheelchairs (including scooters).

4 Wheelchair groups
4.1 General
Wheelchairs appear in a very wide variety of designs, types, models, and sizes. To cope with these circumstances, all wheelchair models are listed into one of four principal groups.
These four principal groups listed in 4.2 to 4.5 comprise wheelchairs with handrims and electrically powered wheelchairs of class A, B, and C.
When measurements are made, the size of the wheelchair is selected according to ISO 7176-5, Clause 6, and equipped and adjusted according to ISO 7176-5, Clause 7, for the respective occupant mass group.
Note: At the present stage, only data for occupant mass group II and III are available. The test results presented are received from measurements of about 38 different wheelchair models (15 manual wheelchairs with handrim propulsion, about 7 of each class of electrically powered wheelchairs. Because the task of GB/T 18029 is to deliver comparable data about typical situations, it is not necessary to support them by large numbers of test wheelchairs and by extensive statistics. Further data collection, in particular for occupant mass group I, and from various sources and with other wheelchair models is in the work plan of ISO/TC 173 SC 1, which is responsible for the elaboration of ISO 7176-5 and this part of ISO/TR 13570-2.
4.2 Wheelchairs with handrims
This principal group comprises wheelchairs with manual rear wheel drive by use of handrims and handrim activated power assisted wheelchairs (HAPAW).
4.3 Electrically powered wheelchairs of class A
This principal group comprises electrically powered wheelchairs that usually have rear wheel drive, are compact and manoeuvrable but not necessarily capable of negotiating outdoor obstacles and therefore are primarily intended for indoor use.
4.4 Electrically powered wheelchairs of class B
This principal group comprises electrically powered wheelchairs that usually have rear wheel drive, are sufficiently compact and manoeuvrable for some indoor environments and capable of negotiating some outdoor obstacles and therefore are intended for a combination of indoor and outdoor use.
4.5 Electrically powered wheelchairs of class C
This principal group comprises electrically powered wheelchairs that usually have front wheel drive, are usually large in size, not necessarily intended for indoor use but capable of travelling over longer distances and negotiating outdoor obstacles and therefore are primarily intended for outdoor use.
4.6 Electrically powered wheelchairs (scooter design)
These are electrically powered wheelchairs with tiller steering. Usually they are large in size, not necessarily intended for indoor use but capable of travelling over longer distances and negotiating outdoor obstacles and therefore are primarily intended for outdoor use.
Note: The values from measurements of scooters are merged into the appropriate class A, B, or C of an electrically powered wheelchair.
5 Typical values and recommended limits for required measurements
5.1 General
The outcome of tests performed with typical wheelchairs and as stipulated in ISO 7176-5, Clause 8 are listed to give an understanding of the state of the art and to provide their recommended limits.
All length dimensions are given in millimetre, all angle dimensions are given in degrees, and all masses are given in kilogram.
