    Abstract - (Show below) - (Hide below)

    Describes requirements and test methods for electromagnetic emissions and for electromagnetic immunity of electrically powered wheelchairs and scooters with a maximum speed of not more than 15 km/h intended for indoor and/or outdoor use by people with disabilities.

    Scope - (Show below) - (Hide below)

    This part of ISO7176 specifies requirements and test methods for electromagnetic emissions and for electromagnetic immunity of electrically powered wheelchairs and scooters with a maximum speed of not more than 15km/h intended for indoor and/or outdoor use by people with disabilities. It is also applicable to manual wheelchairs with an add-on power kit. It is not applicable to vehicles designed to carry more than one person.

    This part of ISO7176 also specifies requirements and test methods for the electromagnetic compatibility of battery chargers intended for use with electrically powered wheelchairs and scooters.

    A reference configuration is specified for adjustable wheelchairs and scooters in order to enable test results to be used for comparison of performance.

    NOTE The term “wheelchair” is used in this part of ISO7176 to cover electrically powered wheelchairs, scooters and manual wheelchairs with an add-on power kit.
