Fire Reaction

The way in which material and construction products react to fire performance is key to ensuring people’s safety in case of fire at a construction site.

“Fire reaction” indicates the way the material behaves as a combustible.

Construction products’ reaction to fire is determined through Euroclasses. The Euroclasses were introduced following a resolution by the Commission (2000/147/EEC), from February 8, 2000, to create a common platform for the comparison of the fire properties of construction materials.

Fire testing of the products is conducted in accordance with harmonised testing methods. As defined by a series of European standards, it includes several tests and related performances:

  • Classification for combustibility. Class A1 is non-combustible and the requirement level cannot be combined with any additional class mentioned below.
  • Additional classification for smoke development, identified by symbol s.
  • Additional classification for burning droplets, identified by symbol d.
