In Germany, the procedure for construction and operational fire protection are
specified by the Fire protection standard DIN 4102, the Model Building Ordinance
(MBO), Regional Construction Ordinances (LBO) and various trade-specific regulations
from professional associations.
Thus the following applies, according to Parts 1 and 2 of DIN 4102:
Building materials like concrete, wood, stone, metal, etc. are divided into
flammable or non-flammable building material classes according to their behaviour.
In contrast, structural members consist of different combustible and non-combustible
building materials. They are not divided into fire classes, rather they are evaluated as a
whole according to their fire resistance duration.
The fire resistance duration F is indicated in minutes and classified according to two
categories:
Components with a fire resistance duration of F30 and F60 are fire inhibiting.
Fire resistant, on the other hand, are all components with a fire resistance of F90,
F120 and F180.
Tested systems like cable, ventilation or utility systems are tested not only for fire
resistance, but also for function capability in the case of fire (e.g. supply lines to sprinkler
systems). The fire resistance duration of these systems is specified with e. g. E30
to E120 for electrical cable systems and/or with L30 to L120 for ventilation lines.
The fixings that are used to anchor these systems must have at least the same fire
resistance duration.
The standard temperature-time curve (ETK) of DIN 4102 and ISO 834 is based on a
simulation of actual fire conditions and forms the evaluation basis that is valid worldwide
for determination of the fire resistance duration. Besides that, there are other temperature
curves for special fire exposures, e. g. the hydrocarbon curve for fire causing with
combustible liquids or the RAB/ZTV tunnel curve (Germany) and/or the Rijkswaterstaat
tunnel curve (Netherlands), which describe tunnel fires.
