Relationship with other publications

This part of BS 8663 is the first in what is expected to be a series of standards covering watermist system components.

It is intended to be read in conjunction with BS 8458 for residential and domestic watermist systems or BS 8489‑1 for industrial and commercial watermist systems.

Information about this document

Watermist nozzles are for use in watermist systems and are designed to provide an additional degree of protection of life and property, above that already achieved by the building design and the installation of smoke and/or fire detectors and systems. This British Standard presumes that the watermist protection will form part of an integrated fire safety system.

Product certification/inspection/testing. Users of this British Standard are advised to consider the desirability of third‑party certification/inspection/testing of product conformity with this British Standard. Appropriate conformity attestation arrangements are described in BS EN ISO 9001. Users seeking assistance in identifying appropriate conformity assessment bodies or schemes may ask BSI to forward their enquiries to the relevant association.

It has been assumed in the preparation of this British Standard that the execution of its provisions will be entrusted to appropriately qualified and experienced people, for whose use it has been produced.
