Tests under calorimetry hood

Fire safety often leads managers to seek to determine the power released by the fire.

We have a calorimetry hood that can be used to characterize the combustion of products or equipment. The tests can be performed in free combustion (simulation of the outbreak of fire) and in forced combustion (simulation of combustion of the item in the fire phase).
The power of the fire is determined from the quantity of oxygen consumed (Thornton method) or from the mass loss, continuously measured.
Additional measurements can be made:
  • Measurement of the thermal radiation at a given distance
  • Characterization of fume composition: CO, CO2, NOx, HCl, HBr, HF, VOCs, PAHs, formaldehyde, acrolein, PCB, dioxins, furans
  • Measurement of smoke opacity
The issues involved in water-based fire extinguisher systems: the composition of the extinguishing water and the composition of the fumes in the extinguishing phase can also be experimentally studied by CNPP.
