The fire resistance classes are an elementary component of the respective state building regulations. These specify the building supervisory requirements with regard to fire protection. These fire protection regulations should prevent fires from spreading to adjacent buildings and make it easier for the fire department to fight fires. The longer individual components (stairs, doors, ceilings, walls, pillars, etc.) withstand a fire, the higher the chance of successfully combating the fire.

As part of the fire resistance classes, individual components are classified according to how long they can withstand a fire in minutes (30, 60, 90, 120, 180). A distinction is made in the components T (fire doors), F (elevated components) and R (piping). ‘Fire retardant’ is defined as parts that resist fire for 30 to 60 minutes, ‘fire resistant’ parts that endure for 90 to 120 minutes, and components that resist fire for 180 minutes are referred to as ‘high fire resistant.’

In this case, buildings in solid construction meet the requirements of fire protection usually without further measures, while in wooden structures may require proof by the structural engineer.

Building materials can not be classified in fire resistance classes, but are divided into non-combustible and combustible substances.
