Watermist components are approved against the relevant LPCB schedule of requirements for watermist components. The schedules are specified in SD0231 and are based on existing LPS and EN standard test methodologies from both sprinkler and gaseous system components wherever possible.
As part of the LPCB approval requirements the production facilities must carry ISO 9001 with a suitable scope. The Factory Production Control (FPC) processes are also audited by LPCB to ensure the ongoing conformity of the production process.
In order to function correctly the approved components must be specified, installed and maintained in accordance with the manufacturer's technical instructions.
Watermist component approval does not mean LPCB watermist system approval. LPCB watermist system approval requirements are set out under Watermist Systems.
