The above panels meet the requirements of NZBC 3.4(A) Internal Surface Linings

In Europe, the reaction to fire of construction products and materials are classified using the criteria and test methods described in EN 13501-1:2007+A1:2009. The classification levels are A1, A2, B, C, D, E and F, from least to most combustible.

This standard provides the reaction to fire classification procedure for all construction products (including wood-based products). It includes products incorporated within building elements. It is referenced in the harmonised European standard for wood-based panel products, EN 13986.

The Single Burning Item (SBI) as described in EN 13501-1:2007+A1:2009 is a test method for determining the reaction to fire behaviour of building products when exposed to the thermal attack by a propane burner. The results of this test, using a Fire Growth Rate (FIGRA ratio) have been correlated for MBIE to the ISO 9705 Group Numbers and the requirements of NZBC Clause 3.4(a) in the same manner as the ISO 5660 cone calorimeter test.

The co-relation of wall and ceiling surface finishes derived from Australian or European classifications to the Group Number requirements of NZBC Clause 3.4(a) can, without the need for further testing, be taken as described in the table shown.
