3 Terms and definitions
The terms and definitions as defined in GB/T 14729, GB/T 18029.7-2009, GB/T
18029.8-2008, GB/T 18029.11-2008 and GB/T 18029.15-2008 as well as the
following terms and definitions apply to this document.
3.1
Electrically powered wheelchair
A wheeled personal mobility device with seat support that can be operated
by an occupant or caregiver, driven by one or more motors, with electrically
Supplementary weights
The object used, when the testing personnel is used instead of the test
dummy, to increase the weight, so that the total load and load distribution of
the wheelchair is consistent with the corresponding dummy (see 5.5 of GB/T
18029.3-2008).
4 Classification and model naming-principle
4.1 Electrically powered wheelchairs are divided into three categories according
to the use requirements.
Electrically powered wheelchair for indoor use is represented by the
uppercase Chinese pinyin letter N.
Electrically powered wheelchair for outdoor use is represented by the
uppercase Chinese pinyin letter W.
Electrically powered wheelchair for road use is represented by the
uppercase Chinese pinyin letter L.
Note. The scooter also includes the above three categories.
4.2 Model naming-principle can be carried out according to the manufacturer's
corporate technical specifications, but the principles for model naming-principle
must be stated in its product specification (see 3.7).
4.3 It shall indicate the type of product (indoor, outdoor or road type) in the
model.
5 Requirements
5.1 Surface requirements
5.1.1 The outer surface of the wheelchair’s parts and all the parts that can be
touched by the hand shall be flat and smooth, free from sharp edges, burrs,
sharp corners, etc.
5.1.2 All soft packed parts of wheelchairs shall be soft and elastic, the seams
shall be firm and tidy. There shall be no defects such as wrinkles, fading,
jumpers and breakage on the outer surface.
5.2 Assembly requirements
5.2.1 After the wheelchair is assembled, its functions shall be able to be used
normally according to the manufacturer’s instructions. All rotating and moving
5.6.6 Overvoltage protection of controller
When charging, the battery’s voltage may exceed its rated voltage. At this
higher voltage, the wheelchair shall not malfunction.
5.6.7 Protection of motor stalling
Once the wheelchair is hitting an obstacle in the driving process (such as a
higher curb stone of the sidewalk), the drive motor will stall. Therefore,
wheelchairs shall have protective measures to prevent motor from overheating
or permanent damage.
5.6.8 Insulation
The wheelchair’s frame, motor’s housing, battery’s housing and controller’s
housing shall not be connected to any other live parts of the battery pack or
electrical system. The DC current between them shall be not more than 5 mA.
5.6.9 Protection of non-insulated electrical components
Users and caregivers shall not be shocked or burnt by contact with non-
insulated parts when using a wheelchair, meanwhile the wheelchair shall not
malfunction due to this.
5.6.10 Circuit protection
All wires and connections of the wheelchair shall be properly protected from the
overcurrent of the wheelchair’s power supply or the externally connected power
source.
5.6.11 Test of power consumption
The power consumption of wheelchairs is not allowed to exceed 15% of the
manufacturer’s specified indicators.
