Fire Resistance Tests of Bearing Construction Systems

CSI classifies the fire resistance of numerous load-bearing construction systems and subdivision of premises subject to fire prevention regulations.

CSI is a laboratory authorized by the Ministry of Interior, according to the D.M. 16.2.2007 and is also an accredited laboratory (the only one in Italy) by the national accreditation body, Accredia, for the classification of fire resistance of load-bearing elements, separating and not, both horizontal (floors) and vertical (masonry), in the field of civil and industrial construction.

CSI laboratory carries out tests and classifies the fire resistance of load-bearing floors since the beginning of its activity in 1988. It was the first in Italy to perform tests and to issue classifications of vertical load-bearing systems and to obtain authorization to operate in scope of the experimental fire resistance verification based on the Decree of the Ministry of Interior of February 16, 2007 according to the new European standards.

CSI boasts almost thirty years of experience in the experimental verification of fire resistance, in particular for floors of the most different types (mixed steel and concrete, predalle, floors with lightening, in wood) and for special vertical load-bearing elements (wooden and mixed walls wood-slabs, walls in modular elements in reinforced concrete).

In detail, CSI offers the testing and classification service for systems:

  • Masonry, block or prefabricated walls (EN 1365-1);
  • Slabs (EN 1365-2);
  • Beams (EN 1365-3);
  • Balconies and walkways (EN 1365-5);
  • Stairs (EN 1365-6).

To characterize the fire resistance of all these systems, CSI is also an accredited body according to UNI CEI EN ISO / IEC 17025.
