The following list gives you an idea of what we test:

  • Leakage tests on the person using either SF6 or NaCl (inward leakage und total inward leakage)
  • Measuring the field of vision
  • Measuring breathing resistance and the CO2-level of air inhaled
  • Examining the impact of heat radiation and flames
  • Field experiments and performance tests
