Fire tests

Eurailtest performs tests in its lab dedicated to fire testing to check the behaviour of materials under fire conditions and to ensure that they comply with standards.

Fire behaviour of cables

Check the behaviour of electric cables under fire conditions and conduct type approval tests for the EC marking of cables.

Tests objectives :

  • Assess the ability of cables not to propagate fire via 3 tests:
    – 1 kW flame propagation
    – Fire propagation on stranded wires
    – Fire propagation on ribbon cables
  • Evaluate heat generated by measurement of oxygen consumption coupled with measurements of fire propagation on ribbon cables
  • Characterize smoke toxicity and opacity from cables in the event of fire.

Tests facilities :

  • 27 m3 test chamber
  • 1 kW flame
  • Testing booth
  • Test device for ribbon cables (with or without calorimeter hood)

Accreditations :

ISO/IEC 17025 awarded by COFRAC

Testing norms :

EN 61034 – Measurement of smoke density of cables burning under defined conditions

NF C 32-070 – Classification tests on cables and conductors with respect to their fire behaviour

IEC 60 332 – Tests on electric and optical fibre cables under fire conditions – Procedure for 1 kW pre-mixed flame

EN 50266-2-4 et EN 50305 (§9.1)- Test for vertical flame spread of vertically-mounted bunched wires or cables

EN 50399 – Heat release and smoke production measurement on cables during flame spread test

EN 45545 – Railway applications – Fire protection on railway vehicles

Fire behaviour of materials

Check the compliance of materials intended for rolling stock with regard to fire behaviour.

Tests objectives :

  • Assess fire behaviour of railway materials through various measurements:
    – Toxicity – by gaseous effluent dosage
    – Smoke opacity in a non-renewed atmosphere
    – Behaviour of materials under intermittent thermal loads
    – Threshold limit value of oxygen for sustaining combustion
    – Critical heat flux
    – Critical flux at extinguishment
    – Oxygen consumption calorimetry of rail materials
  • Categorize materials according to requirement levels

Tests facilities :

  • Smoke chamber combined with a Fourier transform infrared analysis unit
  • Smoke chamber
  • Radiant heating panels (horizontal and vertical)
  • Cone calorimeter

Accreditations :

ISO/IEC 17025 awarded by COFRAC

Testing norms :

EN 45545 – Railway applications – Fire protection on railway vehicles

NF F16-101 – Rolling stock – Fire behaviour – Choice of materials

NF F16-102 – Railway rolling stock – Fire behaviour – Choice of materials, application to electric equipment
