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)
