5. Conclusion

The fire behavior of electrical cables is a critical issue for the safety of modern infrastructures. In the event of fire, cables can not only spread the blaze rapidly, but also release toxic fumes that complicate the evacuation of occupants and the response of emergency services. A thorough understanding and rigorous control of their behavior are therefore essential to minimize risks and protect human life and property.

Approaches to reaction and resistance to fire have evolved considerably over the years. The transition to European classification systems, notably with the introduction of Euroclasses, marks an important step in the harmonization of safety standards. Test methods are becoming increasingly sophisticated, making it possible to accurately assess the performance of cables in a fire situation, both in terms of flame propagation and heat and smoke production....
