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
