Flooring
The New Zealand Building Code, Section C, 1-6 is the part of the Building Code relating to fire.
In 2012 a different fire test method for floor coverings: Critical Radiant Flux tested to ISO 9239:1 2010.
The code calls for flooring to comply with a MINIMUM critical radiant flux when tested to ISO 9239-1:2010 of between 1.2 and 4.5 kW/m² depending on the area within the building and the building's Risk Group.
Walls
The Building Code uses a different fire test method for wall coverings: ISO 9705. Tests performed under ISO 5660 and EN13501 are also accepted. The results from the test provides a material group number. All test methodologies also provide a smoke index rating, which may or may not be required depending on the building's risk group. Group 1s is the highest fire and smoke rating applicable to Walls.
