DIN EN 50491-4-1:2012-11

This European Standard specifies the general functional safety requirements for HBES/BACS following the principles of the basic standard for functional safety EN 61508. This standard identifies safety issues related to products and their installation. The requirements are based on a risk analysis in accordance with EN 61508. The intention is to allocate all safety requirements for HBES/BACS products in their life cycle. This standard only addresses HBES/BACS products. This standard is addressed to committees that develop and modify HBES /BACS product/system standards or, where no suitable HBES/BACS product standards addressing functional safety exist, to product manufacturers. HBES/BACS products in this European Standard are for non-safety related applications. Additional requirements for safety related HBES/BACS according to EN 61508 will be defined in Part 4-2 of the EN 50491 standard series. The responsible committee is K 716 "Elektrische Systemtechnik für Heim und Gebäude (ESHG)" ("Home and Building Electronic Systems (HBES)") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
