Product Overview

Summary of this standard

BS EN 12845:2004+Amendment 2:2009 specifies requirements and provides recommendations for the design, set-up and maintenance of fixed fire sprinkler systems in buildings and industrial plants. It also covers any addition, extension, repair or other modification to a sprinkler system but not to water spray or deluge systems.

Minimum construction details of buildings are identified for satisfactory performance of complying sprinkler systems.
