This service provides quantitative fire behavior analysis of construction materials using the Cone Calorimeter method, one of the most widely recognized small-scale fire testing techniques in the building and materials industry. It allows for detailed measurement of ignition time, heat release rate, mass loss, smoke production, and CO/CO₂ emissions, making it an essential tool for understanding the reaction to fire of materials and contributing to Euroclass fire classification.
The Cone Calorimeter test is governed by EN ISO 5660-1 and ASTM E1354, and simulates fire exposure by subjecting a horizontally placed sample to controlled radiant heat flux (typically between 25–75 kW/m²) from a conical heating element. A spark igniter introduces flame at a predetermined time, and the system continuously records how the sample behaves in response to fire.
Key parameters captured include:
-
Time to ignition
-
Peak heat release rate (HRR)
-
Total heat released (THR)
-
Effective heat of combustion
-
Smoke production rate
-
Mass loss rate
-
Gas emissions (CO, CO₂)
The test requires flat samples of 100 mm × 100 mm, with a thickness up to 30 mm. Materials can include plastics, insulation, coatings, composites, or bio-based products—either homogeneous or layered.
This method is especially useful in early product development, where comparative fire behavior analysis is critical. It also provides essential data to support numerical fire simulations, material screening, and regulatory submissions, particularly for Euroclass B–E products.
NTUA’s fire testing lab is certified under ELOT EN ISO/IEC 17025, ensuring high measurement accuracy and standard compliance. Clients receive a detailed test report with raw data, graphs, and interpreted results.
