NZS 4510:2022

This revision of NZS 4510 introduces a number of changes to the 2008 edition. The purpose of this standard is to set out minimum technical and performance requirements for fire hydrant systems. Hydrant systems are primarily for fire brigades to use when they are dealing with fire emergencies in buildings, but hydrant systems can also be found outside buildings for use on exteriors and to cover external fire exposure and risk.
