Classifications of reaction to fire

The assessment yardstick for reaction to fire of building materials in Europe is a classification system which was decided on by the European Committee for Standardisation (CEN) in 2001 with the series of standards DIN EN 13501 Classification of reaction to fire of construction products and building elements. This specifies uniform fire protection requirements throughout Europe. According to DIN EN 13501-1 construction products are classified into seven European classes A1, A2, B, C, D, E and F.

In addition, the side effects of fire such as smoke production (s = smoke, classes s1, s2 and s3) and flaming droplets/particles (d = droplets, classes d0, d1 and d2) of construction materials are considered.

Preventative structural fire protection - Fire graph

The effect of fire on building structures is simulated on the basis of temperature-time graphs. On the basis of these temperature graphs, the requirements for the tunnel construction, such as the thickness of the fire protection cladding and the design of escape and rescue facilities, is developed. The aim of these specifications is to protect the tunnel construction against excessive temperatures in case of fire.
