Non-Combustible Materials

Building Code of Australia

The Building Code of Australia nominates materials to be non-combustible materials (non-combustible elements) throughout Parts C1, C2 and C3. Materials are deemed to be non-combustible materials if they are tested in accordance with AS 1530.1-1994 Methods for fire tests on buildings materials, components and structures – Combustibility test for materials, or is nominated in Part C1 Fire Resistance and Stability clause C1.12 Non-combustible materials under the building regulations. This clause nominates materials that are combustible but may be used wherever non-combustible materials are nominated. Non-combustible materials should be nominated as an essential safety measure by the building surveyor/building certifier.

Essential Safety Measures Audit – Non-Combustible Materials

An essential safety measures auditor to ensure fire safety compliance must be aware of the likely installation location of non-combustible materials under the BCA for the various classes of occupancy. Although nominated in the essential safety measures determination/ schedule, non-combustible materials can be difficult to detect, but when found ‘breached’ should be nominated in the building’s essential safety measures logbook to allow the signing of the Annual Statement, Annual Certificate Compliance, Annual Fire Safety Statement and Annual Maintenance Statement.
