ISO 4190-5:2006 specifies the control devices, buttons and indicators to be provided when a lift (US: elevator) is constructed and installed, taking into account the type of control intended for the lift and also ensuring the ease of access for disabled persons (motor and/or sensory). It also specifies the requirements for handrails when provided in the car. It is applicable to lifts of classes I to IV and VI as defined in ISO 4190-1 and ISO 4190-2.
