School of Civil Engineering

The University of Queensland operates a state-of-the-art fire laboratory in the heart of the University’s St Lucia Campus.  The equipment in the laboratory allows testing – from the very small-scale material compositions to full-scale structural fire testing.

Our facilities help our researchers and commercial partners develop a better understand their materials or assemblies. Consequently, although much of the laboratory equipment is capable of performing the standard tests required for regulatory compliance, we do not issue standard testing certificates.  We prefer to help develop products that deliver enhanced performance, rather than products that simply pass the test.

If you are interested in identifying the fire performance of a particular material or product, UQ Fire will be able to help you. For further information, contact us at

The Lab

The Fire Lab is located in the Frank White Annex and is comprised of a series of spaces that each house state of the art equipment. There is sufficient space in the lab to allow multiple pieces of equipment and tests to run simultaneously – from small scale testing to larger scale calorimetry.

There are several extraction hoods. The demonstration hood allows medium scale experiments and classes to be conducted for students and visitors. The “flashover” box and “fire tornado” are particularly popular amongst our visitors.

The larger scale hood can accommodate a fire up to 2MW in size (roughly equivalent to a sofa fire). The exhaust for the large hood is equipped with a calorimetry system to allow the fire size to be measured as a function of time. This permits larger scale testing of composite materials to be conducted to determine their heat release rate.

iCone Calorimeter

The cone calorimeter (iCone) allows the behaviour of samples of material to be analysed under a range of heat fluxes. Analysis of the combustion gases allows a charaterisation of the heat release rate of the material. Simultaneous measurement of mass loss and smoke production is also conducted.

The Cone Calorimeter is one of the most extensively used bench scale pieces of equipment in fire testing as, although it has been developed for standardised testing, it can be used to explore a wide range of material behaviours. It is based on the principle of oxygen consumption calorimetry and collects and measures the combustion products of sample materials.

It is used to determine the response of materials exposed to controlled levels of radiant heating, supplied by a conical radiant electric heater. It can test a range of combustible materials such as furniture upholstery, timber, and plastics; it can also be used to test non-combustible products to analyse their reaction to imposed heat flux.

Testing in the Cone Calorimeter can provide results for:

  • Sample heat release
  • Critical heat flux
  • Time to ignition of the specimen
  • Effective heat of combustion
  • Smoke production

The iCone has been standardised in accordance with ISO 5660, and can run standard tests as per AS/NZS 3837.

Fire Propagation Apparatus

The Fire Propagation Apparatus (FPA) is used to evaluate the flammability of materials and products; however, unlike the cone calorimeter, the heat is supplied by infrared heating lamps. The FPA also provides control over the oxygen environment around the sample; it is designed to obtain the transient response of such materials subject to prescribed heat fluxes in low oxygen or high oxygen environments.

The instrument can be used to determine “Fire Propagation Index” and the same parameters that can be obtained using the cone calorimeter. The FPA is specially designed for testing semiconductor fabrication materials, underground mine belts and cables.

The FPA was developed by FTT and FM global and has been standardised in accordance ISO 12136.

Mass Loss Calorimeter

This instrument allows material samples to be heated in a highly controlled manner while simultaneously measuring the mass loss of a sample. Consequently, it is possible to understand how material degradation occurs and provides a means for assessing materials, products, or assemblies, for mass loss, critical heat flux and time to ignition.

The mass loss calorimeter is often used as a precursor to cone calorimeter testing.

Large Scale Heat Release Analyser

The fire lab is equipped with a large scale extractor hood. This device uses oxygen consumption calorimetry to calculate the heat release rate of larger scale products or assemblies. The hood is ideal for characterising the fire behaviour of large objects that are composed of many different materials. For example – future, wall materials, small room configurations or even a Christmas tree!

The analyser samples the gases extracted by a large exhaust system capable of accommodating a 2MW fire.

Transient Plane Source

The Transient Plane Source (TPS) measures thermal conductivity, specific heat and diffusivity of solid and liquid materials from building materials to textiles products. The measurement can be performed in a wide range of temperatures from 0°C Celsius to 1000°C.

The transient plane source is a highly precise measurement device that can be used to derive the fundamental material properties required for thermal modelling of materials.

Muffle Furnace

The fire lab has two muffle furnaces; this is a high-temperature furnace capable of heating samples to 1200°C.  These are typically used to determine the proportion of a sample is non-combustible and non-volatile (i.e., ash). Alternatively, it can be used to expose samples to a temperature or a specific period of time to allow subsequent characterisation of physical changes or mechanical properties.

Thermo-gravimetric Analysis and Differential Scanning Calorimetry (STA6000)

The thermo-gravimetric analysis (TGA) is a method of thermal analysis in which changes in physical and chemical properties of materials are measured as a function of increasing temperature. TGA is commonly used to determine selected characteristics of materials that exhibit either mass loss or gain due to decomposition, oxidation, or loss of volatiles (such as moisture). Common applications of TGA are: materials characterization through analysis of characteristic decomposition patterns, studies of degradation mechanisms and reaction kinetics, determination of organic content in a sample, and determination of inorganic (e.g. ash) content in a sample, which may be useful for corroborating predicted material structures or simply used as a chemical analysis.

Differential scanning calorimetry (DSC) is also a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. The DSC allows precise measurements of heat capacity and can be also used for calculation of enthalpies of chemical reactions.


Fourier Transform Infrared Spectroscopy

Fourier Transform Infrared Spectroscopy (FTIR) is a gas analysis method that allows analysis of gases with respect to their composition.  The analyser passes mid-infrared wavelength radiation through gas samples and measures the absorption. Quantification of gases is performed with respect to specific peaks on the IR absorption spectrum and correlated with a known database of chemical compositions.

The FTIR is connected by a heated transfer line to the Simultaneous Thermal Analysis instrument (STA6000). The testing procedure typically requires a small sample of material to be gradually heated in the STA. The gasses released by the samples are then collected and passed through the FTIR analyser. This allows the key parameters of the material to be quantified and the degradation of a material with temperature to be understood.

Integrating Sphere

The integrating sphere is a device that coupled with the FTIR allows determining optical properties of materials such as absorptivity, reflectivity, and transmissivity at a different wavelength. The beam of the FTIR passes mid-infrared wavelength radiation through the integrating sphere with a sample attached to it. Then, radiation reflected by and transmitted through the tested material is quantified and optical properties determined. The integrating sphere can be used with a DTGS or an MCT detector, providing different range of accuracy and sensitivity.

Optical properties of materials in the mid-infrared are key to develop accurate heat transfer and pyrolysis models for materials under conditions of severe heat exposure from fires. The use of this device allows to significantly decrease the uncertainty in fire testing, especially when using radiant devices such as the Cone Calorimeter, the Fire Propagation Apparatus, or the modular array of radiant panels.

Modular Radiant Burner Array

This system is a medium-to-large scale testing device comprised of a modular array of radiant burners designed by GoGaS (Dortmund, Germany). It is used for structural fire and fire testing and (unlike furnace testing) offers a very high level of control in terms of radiant flux on the surface of a sample.

The radiant burner array consists of four sets of 2x2 burners (i.e. 16 single burners) and can be used to replicate one to four sided heating regimes. The burners are powered by natural gas that is premixed with air directly before the porous surface of the burners. Once ignited, the premixed flame heats up the highly porous medium and radiates a consistent thermal load.  Heat fluxes up to 150 kW/m2 are possible with the system – making it ideal for any fire research application.

The system is movable and configurable to any test set-up and can be used in conjunction with large scale loading actuators in the structures lab. Structural fire tests of steel, concrete, and other non-combustible material can be carried out in the structures lab. Combustible material tests can be completed in the fire lab under one of the many extraction hoods.
