Fire resistance test furnaces are the key equipment used to measure how well building materials and products can stand up to fire. They work by simulating a controlled fire environment and measuring different failure points. The primary function of the equipment is to apply precise thermal loads according to international and national time-temperature curves, enabling the verification of a specimen’s ability to maintain structural integrity (E), insulation (I), and load-bearing capacity (R) over a required duration. These systems facilitate the identification of failure modes and ensure compliance with stringent fire safety regulations.
Thermal Performance
Maximum operating temperature up to 1300°C, capable of following standard, hydrocarbon, external fire, and other specialized time-temperature curves.
Loading Systems
Integrated servo-hydraulic loading frames for structural tests to simulate mechanical loads during fire exposure.
Ancillary Systems
Comprehensive solutions including water spray impact test apparatus, total smoke production and smoke leakage measurement systems, and high-capacity fume purification units for exhaust gas treatment.
Control & Measurement:
Fully automated control of temperature, pressure, and combustion. Advanced data acquisition for furnace temperature, specimen back-face temperature, displacement, and pressure differentials.
Creating a Controlled Fire
▪The furnace uses an array of gas burners to create a uniform fire inside a sealed chamber
▪A computerized control system carefully follows standard time-temperature curves
▪The system controls air flow and pressure to make sure heat spreads evenly
Measuring When Products Fail
▪Integrity failure: Detects when flames break through using special cotton pads or gauges
▪Insulation failure: Measures temperature rise on the “cold side” using multiple thermocouples
▪Load-bearing failure: Uses hydraulic systems to add weight while monitoring how much the product bends or deforms
Special Testing Capabilities
▪Water spray systems to simulate firefighting conditions
▪Smoke measurement systems
▪Pressure control to simulate wind conditions during fires
