ISO 16201:2006 specifies functional and technical requirements and test methods for environmental control systems intended for use to alleviate or compensate for a disability. Such systems are also known as electronic aids to daily living. The aim of ISO 16201:2006 is to provide safety requirements and recommendations for manufacturers of such environmental control systems. Target devices are not covered by ISO 16201:2006. Technical requirements for items of equipment connected within the system are to be covered by their own specific standards, e.g. adjustable beds.
