Tunnel construction
Performance of fire tests on electric cable systems (including cables, support systems and possible fire protection systems) to assess the fire behaviour in respect of the circuit integrity with fire stressing from outside.
The area of application is limited to cables with a nominal voltage of up to 1 kV. The functional integrity of cable systems assessed in accordance with these Standards does not cover a voltage drop or a reduced current carrying capacity due to a temperature related increase in resistance.

Determination of the load bearing capacity of fasteners in the most diverse substructures with different fire scenarios (in accordance with RABT/ZTV-ING tunnel curve or DIN EN 1363-1) to determine the failure time and cause of failure over a previously defined test duration on the basis of TR020 (EOTA TECHNICAL REPORT TR 020 "Evaluation of Anchorages in Concrete concerning Resistance to Fire [May 2004 edition]).

Performance of fire tests on fire protection housings to verify the fire resistance duration of the space enclosing construction with a fire incident from the inside or outside. The bases for these tests are the blueprints of the approval principles for the testing and assessment of fire protection housings by Deutsches Institut für Bautechnik. It is possible to implement fire scenarios which deviate from DIN EN 1363-1 and DIN EN 1363-2.
