Fire behaviour of cables

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

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.
