Measurement of heat release rates with oxygen consumption calorimetry is widely used nowadays for several purposes, such as research, materials development, regulation compliance and fire safety engineering. This can be applied both to cone calorimeters and to room-corner tests.

At its various premises, Efectis is able to answer to all your heat release measurement problems, providing calorimetric measurements from a few kilowatts to tens of megawatts:

  • 2 cone calorimeters for regulation (EN 45545-2, IMO HSC code or MSC circ 1006), input data for modelling and research purposes – one equipped upon request with FTIR and other additional measurements such as PIV
  • 1 oxygen-controlled atmosphere calorimeter (Fire Propagation Apparatus)
  • 1 calorimetric table up to 50 kW, for ad hoc tests, objects and panels (e.g. ISO 21367)
  • 4 calorimeters, 300 kW, for tests such as SBI (EN 13823), cable trays (EN 50399) and ad hoc tests
  • 1 calorimetric hood, 1.5 MW, for finished objects
  • 1 calorimetric hood, 5 MW, for room-corner test (ISO 9705), sandwich panels (ISO 13784-1) and a lot of other tests (furniture, electrical cabinets, etc). Room-corner is the reference test scenario for Euroclasses in Europe and is used also for building products in Oceania
  • 1 calorimetric hood, 10 MW, dedicated mainly to FSE studies of storage facilities
  • 1 calorimetric hood, 9x9x9m, 20 MW for your biggest and craziest projects, such as heat release rate measurement for a building section or a 9m façade
  • Efectis also performs calorimetric measurements in situ, e.g. for tunnels up to 200 MW.

This complete offering allows Efectis to answer to all your questions and needs about heat release rate measurements. A lot of this equipment is under ISO 17025 accreditation.

On request, Efectis can also study additional aspects in real fire conditions as such

  • effect of water mist suppression or any other suppression systems on heat release
  • input and validation data for any CFD code applied to fire
  • gas concentration yield
  • particle and soot yield
  • thermal transfer to structural element or fire resistance system
  • fire spread conditions on furniture
