Introduction

With battery charger and run electric wheelchairs can not bring significant electromagnetic disturbance to the environment, on the contrary, in normal use Electromagnetic disturbance can not significantly reduce performance. Since the wheelchair often travel on roads, and therefore need to be fixed or mobile communication device RF fields and other sources of electromagnetic disturbance emitted by immunity. Wheelchairs accidental movement or change direction, can cause injury.

This section GB/T 18029 specifies the requirements and test methods wheelchairs and battery charger. In a typical environment of use, the wheel Chairs and car battery charger can be exposed to a reasonably foreseeable risk of electromagnetic interference and electrostatic discharge-related, resulting in damage to other equipment or Risks associated with operation of the instruments to minimize electromagnetic fields.

According to the use of wheelchairs and related environmental risks, and to determine the upper frequency limit of RF radiation immunity test level requirements. To this end, Wheelchairs with requirements related to their use as medical devices consistent with the requirements, however, the charge is consistent with the requirements of used household appliances equipment.

Wheelchairs - Part 21. electric wheelchairs, Electromagnetic compatibility and electric scooter battery charger Requirements and test methods Warning. If adequate safety precautions are not taken, this section requires GB/T 18029 using the test procedure, things can cause harm it. This section refers only to technical suitability, does not relieve the manufacturer or testing laboratory health and safety related liability.

1 Scope

GB/T 18029 in the provisions of this section does not exceed the maximum speed of 15km/h for the disabled indoor and (or) outdoor electric wheelchairs and Requirements and test methods for electric scooter electromagnetic radiation and electromagnetic immunity. This section GB/T 18029 also applies to the external electric drive help Manual wheelchair force kit, do not apply to more than one person can take the load of the vehicle.

GB/T 18029 This part also provides electromagnetic compatibility and electric wheelchairs and electric scooters for use with the battery charger Requirements and test methods.

To facilitate performance comparison test results, adjusted for wheelchair and scooter, given the reference configuration.

Note. GB/T 18029 in this section the term "wheelchair" including electric wheelchairs, electric scooters and electric drive external power kit manual wheelchair.
