Fire Test Reports

Provides an assessment of the critical radiant flux (CRF – kW/m2) and smoke development rate (<750 percent-minutes) achieved for a range of timber species used as solid timber flooring of 12mm minimum thickness and plywood flooring of 15mm minimum thickness either installed on a substrate (e.g. 19mm particleboard) or not on a substrate. (Valid to 30/04/2026)

Provides an assessment of the Group number and average specific extinction area (<250 m2/kg) achieved for a range of timber species used as wall and ceiling linings as well as the critical radiant flux (CRF – kW/m2) and smoke development rate (<750 percent-minutes) achieved for a range of timber species for use as solid timber flooring of 19mm minimum thickness. (Extended to 31 December 2025 - refer RIR 41117.11 LOE1.3 below)

Provides an assessment of the Group number and average specific extinction area (<250 m2/kg) achieved for a range of timber species of 9mm minimum thickness when used as wall and ceiling linings. This report also assesses the effect of various lining profiles (e.g. V-joint, shiplap). (Extended to 31/12/2025 - refer RIR 45980.10 45981.10 45892.13 LOE4.0 below)

Provides an assessment of the Group number and average specific extinction area (<250 m2/kg) achieved for a range of timber species used in the manufacture of plywood, of 6mm minimum thickness, when used as wall and ceiling linings. This report also assesses the use of polyvinyl acetate (PVA), resorcinol, phenol-formaldehyde (PF), melamine urea-formaldehyde (MUF) and urea-formaldehyde (UF) glues as being acceptable. (Extended to 31/12/2025 - refer RIR 45980.10 45981.10 45892.13 LOE4.0 below)

Provides an assessment of the Group number and average specific extinction area (<250 m2/kg) achieved for “raw” 6mm minimum thickness standard MDF or particleboard, as well as for a range of timber veneer species (up to 1.2mm in thickness), when adhered to standard MDF or particleboard, used as wall and ceiling linings. This report also assesses the use of polyvinyl acetate (PVA) and resorcinol glues as being acceptable. (Extended to 31/12/2025 - refer RIR 45980.10 45981.10 45892.13 LOE4.0 below)

Provides an assessment of the fire resistance performance of low-rise multi-residential timber-frame construction (MRTFC) roof, floor/ceiling and wall junctions intersecting fire-resistant timber-framed walls. Typically, timber char blocks and fire-resistant mineral wool are used to maintain the fire resistance level (FRL) of 60/60/60 and 90/90/90 of the fire-rated wall and prevent fire and smoke spread through wall cavities. (Valid to 30/9/2028)

Provides an assessment of FRL 90/90/90, and resistance to the incipient spread of fire (RISF) of 60 minutes, for timber-framed floor/ceiling systems comprising, one or a combination of, solid timber floor joists, timber and metal webbed engineered floor trusses, timber and metal webbed I-joists as well as glued-laminated (glulam) timber and laminated veneer lumber (LVL) engineered wood products manufactured using resorcinol adhesive utilising two-layers (2) of 16mm fire-grade plasterboard as the fire-rated ceiling lining; and FRL 120/120/120, and resistance to the incipient spread of fire (RISF) of 120 minutes, for timber-framed floor/ceiling systems comprising, one or a combination of, solid timber floor joists, timber and metal webbed engineered floor trusses, timber and metal webbed I-joists as well as glued-laminated (glulam) timber and laminated veneer lumber (LVL) engineered wood products manufactured using resorcinol adhesive utilising three-layers (3) of 16mm fire-grade plasterboard as the fire-rated ceiling lining. (Valid to 31/05/2030)

Provides an assessment that enables the use of Jarrah and Karri in designated BAL 29 bushfire areas when used as 20mm decking on an enclosed, timber-framed deck when constructed adjacent to non-combustible wall cladding. (Valid to 31/05/2030)

Documents the findings of a test simulating a BAL-29 bushfire attack in accordance with AS 1530.8.1-2018 using an unenclosed Radiata pine subfloor system with non-combustible mineral wool insulation fitted between the floor joists.
