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)
