Fire Test Reports

21419 RIR6.0 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 31/12/2026)

This Letter of Extension is provided by Jensen Hughes Fire Testing to extend the validity of their existing timber flooring fire assessment report (21419 RIR6.0) confirming that the previously reported fire performance results remain valid for continued use as evidence of suitability in accordance with the National Construction Code. (Valid to 31/12/2026)

Short Form Assessment Report FCO-3590 provides an assessment of the Group number and average specific extinction area (<250 m2/kg) achieved for a range of 9mm to 19mm thick 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 12mm to 31 mm thickness. (Valid to 31/12/2030)

FAS180355 RIR11.1 provides an assessment of the Group number and average specific extinction area (<250 m2/kg) achieved for various solid timber species, timber veneers adhered to MDF, and plywood when used as wall and ceiling linings. (Valid to 28/02/2031)

Short Form Assessment Report FCO 3437 provides an assessment of the Spread of Flame Index (SOF) and the Smoke Developed Index (SD) reaction to fire performance of various solid timber species, and a limited number of plywood timber species, of 12mm to 25mm in thickness. (Valid to 31/12/2030)

22221A RIR6.0 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)

Short Form Assessment Report FCO-3591 provides an assessment of FRL 90/90/90, and resistance to the incipient spread of fire (RISF) of 60 minutes; 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 with multiple layers of 16mm fire-grade plasterboard as the fire-rated ceiling lining as described. (Valid to 31/05/2030)

Short Form Assessment Report FCO 3600 provides an assessment of the fire-resistance level (FRL) and Resistance to the Incipient Spread of Fire (RISF) performance of various timber-framed and massive timber panel systems based on the NCC Specification C1.13a Fire-protected Timber. (Valid to 30/11/2030)

Short Form Assessment Report FCO-3593 Revision A 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)

FRT210172 RIR1.0 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.
