Fastenings

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
