THE REQUIREMENTS FOR PIPE SUPPORT BY AS2419.1-2017
Section 10 of AS2419.1 sets out pipe supports for a fire hydrant system in a building.
10.4 PROTECTION OF PIPE SUPPORTS
10.4.1 Fire Rating
In a non-sprinkler-protected building where pipework is likely to be exposed to fire, the pipe supports shall have an FRL of not less than 60/–/–, while maintaining a pipe support temperature of not less than 500°C when tested in accordance with AS 1530.4, or other measures shall be taken to prevent early collapse of the pipework and supports when exposed to fire.
10.2 PIPE SUPPORT DESIGN
Pipework associated with fire hydrant systems shall be supported by either—
a) A pipe support system, the individual components of which are in accordance with the requirements of Clause 10.5; or
b) Pipe supports and fasteners that are capable of supporting twice the mass of the pipework filled with water plus a mass of 115 kg at each point of support.
Any sway support system provided shall be independent of the pipe support system.
Where a fire hydrant system is located in an area where a seismic event is likely—
(i) The sway support system shall be determined by engineering analysis
(ii) The importance level used to determine the probability of design events shall be determined in accordance with the Deemed-to-Satisfy provisions of the NCC; and
(iii) An importance level of 2 shall be used to determine the probability of design events in circumstances where the NCC does not apply.
