Structural Members in Fire Safety

Fire Resistance of Structural Members

  • Fire tests to determine the fire resistance of structural members in accordance with DIN EN 1363-1, DIN EN 1364-1, DIN EN 1364-2, DIN EN 1365-1, DIN EN 1365-2, DIN EN 1365-3, DIN EN 1365-4
  • Consultancy and creation of test programmes
  • Creation of fire protection-specific evaluations and expert opinions
  • Fire tests in accordance with national and European standards, e.g. to determine the fire resistance time for structural members, cladding criterion in wooden constructions in accordance with DIN EN 14135
  • Creation of classification reports and reports on the extended scope of application of test results in accordance with DIN EN 13501-2
  • Fire tests in tunnel constructions
  • Fire tests to support approval procedures by building authorities, e.g. in the context of approval in individual cases
  • Fire tests with special superstructures, on special structures, for special uses, according to customer specifications
  • Support during product development, development and coordination of customised test programmes to obtain building authority certificates
  • Development of general building authority test certificates (in accordance with Section 19 Lower Saxony Building Regulations (NBauO))
  • Cooperation with certification bodies in carrying out external monitoring or voluntary external monitoring for quality assurance

Façades and Glazing

Test areas

  • Vertical fire protection glazing in accordance with DIN EN 1364-1
  • Horizontal fire protection glazing in accordance with DIN EN 1365-2
  • Curtain walling in full and partial assembly in accordance with
  • DIN EN 1364-3 and DIN EN 1364-4


Furnaces for tests of glazing and façades

  • Vertical test specimens (L x H): 3 m x 3 m, 4 m x 4 m, 5 m x 5 m
  • Horizontal test specimens (W x L): 4 m x 3 m, 4 m x 4 m, 4 m x 8 m

Fastening systems

Fire tests of fastening systems

  • On beam, ceiling and wall structures
  • Loads under centric tension or oblique load up to 50 kN
  • Special test methods e.g. in accordance with ZTV-ING or RAL GZ656, or test of high temperature behaviour of fastening systems
  • Testing in connection with special substrates such as hollow-chamber ceilings, masonry, torn reinforced concrete
