Preface:

Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).

This Standard supersedes CAN/CSA-ISO/IEC TR 14762-04 (adoption of ISO/IEC TR 14762:2001, first edition, 2001-01). At the time of publication, ISO/IEC 14762:2009 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC.

Scope:

ISO/IEC 14762 sets the requirements for functional safety for Home and Building Electronic Systems (HBES) products and systems, a multi-application bus system where the functions are decentralised, distributed and linked through a common communication process. The requirements may also apply to the distributed functions of any equipment connected in a home or building control system if no specific functional safety standard exists for this equipment or system.

The functional safety requirements of this International Standard apply together with the relevant product standards for a device if any.

This International Standard does not provide functional safety requirements for safety-related systems.
