DIN EN 12845-3:2024-10

This document EN 12845-3:2024 has been prepared by Technical Committee CEN/TC 191 "Fixed firefighting systems", the secretariat of which is held by BSI (United Kingdom). The responsible national standardization committee is Working Committee NA 031-03-03 AA "Wasserlöschanlagen und Bauteile - SpA zu CEN/TC 191/WG 5 und WG 10" ("Water extinguishing systems and components - mirror committee of CEN/TC 191/WG 5 and WG 10" at DIN Standards Committee Firefighting and Fire Protection (FNFW). This document specifies requirements for earthquake protection of automatic sprinkler systems in accordance with EN 12845:2015+A1:2019. This document applies only to locations in earthquake zones in accordance with EN 1998-1:2004+AC:2009+A1:2013, 3.2.1 and the Nationally Determined Parameters. The requirements in this document are based on the principle that certain peak ground acceleration values are considered as an earthquake which require special means. Attention is drawn to EN 1998-1:2004+AC:2009+A1:2013, where a peak ground acceleration above 0,08 g (0,78 m/s²) is considered an earthquake risk. Additional characteristics, NDP and/or NCI can exist in some countries as well as national annexes. The principles defined in this document can be applicable to other water based fixed manual or automatic fire fighting systems, according to local requirements.
