Fixed fire protection systems. Components for watermist systems - Specification and test methods for watermist nozzles algolia-ignore Several figures have been revised1 Scope This British Standard specifies requirements and gives test methods for the construction and performance of open and automatic watermist nozzles for use in watermist systems conforming to BS 8458 or BS 84891. This British Standard does not cover the electrical actuation of watermist nozzles. NOTE 1 Electrical actuation of watermist nozzles is covered in BS 72733 and BS 72735. NOTE 2 All pressure data in this standard are given as gauge
