Wheelchairs - Power and control systems for electrically powered wheelchairs and scooters. Requirements and test methods Ingestion-build-232773 The requirements of PD IEC/TS1 Scope This part of ISO 7176 specifies requirements and associated test methods for the power and control systems of electrically powered wheelchairs and scooters. It sets safety and performance requirements that apply during normal use and some conditions of abuse and failure. It also specifies methods of measurement of the forces necessary to operate controls and sets limits on the forces needed for some operations. This part of ISO 7176 is
