RESNA ANSI  WC-2:2019 Section 14
American National Standard for Wheelchairs - Volume 2: Additional Requirements for Wheelchairs (including Scooters) with Electrical Systems Section 14: Power and Control Systems for Electrically Powered Wheelchairs Requirements and Test Methods
This section of RESNA WC-2 specifies the requirements for the power and control systems of electrically powered wheelchairs, including battery chargers, and associated test methods. It sets minimum requirements for the protection of the wheelchair user during normal use and some conditions of abuse and failure. It also specifies methods of measurement of the forces necessary to operate the controls and sets limits on the forces needed for some operations. This section of RESNA WC-2 is applicable to electrically powered vehicles intended to provide indoor and outdoor mobility for disabled persons whose mass at speeds up to 15 km/h does not exceed 100 kg. It is not applicable to electrically powered vehicles which incorporate devices that need to be connected to a domestic or industrial power supply greater than 100 volts (e.g., those with built-in battery chargers). It does not include requirements on electromagnetic susceptibility or emissions.
