New Zealand Building Code (NZBC)
The product will, if employed in accordance with the supplier's installation and maintenance requirements, assist with meeting the following provisions of the building code:
- Clause C3 Fire affecting areas beyond the fire source: Performance C3.4(a)
FireZone 92 has been tested to EN13501-1:2018 in Europe
achieving a B-d0-s1 classification. The classification is valid for timber substrates with a minimum thickness of 9mm and minimum density of 338kg/m3.
According
to the NZBC C/AS2 Table C1.1 – a B-d0-s1 is the equivalent of a
Group 1-S.
According
to C/VM2 A1.6 – a surface applied system’s fire rating is compliant
on any timber substrate of the same of greater thickness and same or greater
density.
Therefore
FireZone 92 meets a Group 1-S fire rating on timber substrates ≥9mm in
thickness and ≥338kg/m3 in density.
Notes
The FireZone 92 system meets the Group 1-S, Group 1, Group 2-S, Group 2 and Group 3 interior surface lining requires as required by C3.4(a). Outlined in NZBC C/AS2 Clause 4.17.
Timber substrates must be for internal use only, with a minimum density of ≥338 kg/m3 and minimum thickness of ≥9mm.
Timber substrates are defined in NZBC CVM2 Verification Method - Clause A1.6 Table A2 - Timber, Standard grade plywood, hardboard,
fibre/particleboard.
