The Building Code of Australia (BCA) defines the Fire Resistance Level (FRL as the testing period in minutes for three criteria, i.e.:
- 60/60/60 first figure is Structural Adequacy (the ability of a structure to maintain its stability and
load bearing capacity)
- 2nd figure is Integrity (the ability of a structure to resist the passage of flames and hot gases)
- 3rd figure is insulation (the ability of a structure to maintain a temperature below specified limits on the unexposed surface
- being 180 Deg c plus ambient as a maximum allowed at any one point of the unexposed side of the fire wall).
The longest test time recognised by the BCA is 240 minute period 4 hours.
