What is the fire class or Euro class?
‹ Terug naar overzicht- What is the fire class or Euro class?
Answer: The EN50575 standard for cables stipulates that cables must undergo fire tests that are set out in another standard, the EN50399. Standard EN50399 divides electrical cables into fire classes, the so-called Euro classes: B2ca, Cca, Dca, Eca and Fca. These Euro classes indicate the degree of fire propagation. Furthermore, there are additional conditions (s, d and a) that indicate how much smoke is released, how many falling burning droplets, and the toxicity of the fumes. An Eca cable is only self-extinguishing, but a B2ca s1, d1, a1 meets very strict requirements for fire propagation, heat release, smoke development and fumes.
