41 - APPENDIX ZZ LIST OF VARIATIONS TO ISO 7176-14 FOR AUSTRALIA AND NEW ZEALAND

Specifies requirements and test methods for power and control systems of electric wheelchairs (including scooters). Includes vehicles with built-in battery chargers. This Standard is based on but not equivalent to and reproduced from ISO 7176-14:1997.

This part of ISO 7176 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 part of ISO 7176 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.NOTE-Further work is in progress by CEN/TC 293 on electromagnetic compatibility requirements for wheelchairs related to the Medical Device Directive, whilst work in ISO/TC 173/SC 1 will provide specific electromagnetic compatibility requirements for wheelchairs.
