Fire resistant testing

Fire resistance is measured in terms of time (e.g., 30 minutes, 60 minutes, 120 minutes, 180 minutes, 240 minutes etc), indicating how long the material or component can perform its intended function under fire conditions. This measure helps in the design and construction of buildings to enhance safety by using appropriate materials and components that will stop or slow the spread of fire, maintain structural stability, and allow occupants time to evacuate safely.

Fire resistance testing, as described earlier, is a method to evaluate these attributes under controlled conditions. This testing process is a form of destructive evaluation, aiming to simulate the real-world application and conditions the product would face. It involves constructing a sample of the product or material as it would be used in a building, placing it within an appropriate supporting construction within a representative restraint frame, and then exposing it to controlled temperatures in a furnace. These conditions follow internationally recognized time/temperature curves (e.g. standard cellulosic fire curve, hydrocarbon fire curve, tunnel fire etc) to accurately assess the material’s or component’s ability to resist or contain fire, providing a critical assessment of its performance in potential fire scenarios.
