Description

This Standard sets out requirements for the protection of life and property from the consequences of fire, through standardization of design, installation and commissioning of water-based fire protection systems that use water mist as the extinguishing agent.

Scope

This Standard sets out minimum requirements for design, installation and commissioning of water mist fire protection systems using potable water or natural sea water.

It does not provide definitive fire performance criteria.

The Standard is limited to systems that have demonstrated acceptable levels of performance in fire tests as part of a listing process. They may be arranged as total flooding, zoned or local application systems and designed for suppression or extinguishment. Where the water supplied to the system is from an unlimited supply, as defined in Clause 5.1.2, the system may also be designed for fire control.

This Standard establishes minimum requirements for water mist technology and is based on sound engineering principles, test data and field experience.

Water mist systems are specialized fire protection systems. Design and installation of these systems requires specialized training, knowledge and experience.

For systems using additives, the requirements of Sections 2 and 12 apply.

Water mist fire protection systems are herein referred to as 'a system' or 'the system'.
