scope:

This document specifies requirements, test methods, performance criteria, and manufacturer's instructions for smoke alarms that operate using scattered light or transmitted light (Type A- optical) or ionisation (Type Bionisation), intended for household or similar residential applications. This document includes additional requirements for smoke alarms which are also suitable for use in leisure accommodation vehicles. For the testing of other types of smoke alarms, or smoke alarms working on different principles, this document should only be used for guidance. Special features of smoke alarms or special characteristics and developed for specific risks, are not covered by this document. This document allows, although it does not require, the inclusion within the smoke alarm of facilities for interconnection with other similar smoke alarms and/or accessories, and for alarm silencing. Where such facilities are included, this document specifies applicable requirements. This document does not cover the requirements for devices intended for incorporation in systems using separate control and indicating equipment. NOTE Certain types of smoke alarms contain radioactive materials. The national requirements for radiation protection differ from country to country and they are not specified in this document. Such smoke alarms should, however, comply with the applicable national requirements.
