Fire resistance testing - Buildings

Fire resistance tests in the building sector include all French regulatory evaluations (ranking of both stiff "M" and flexible "M"), as well as the European regulatory ranking (Euroclasses, ignitability, Higher Heating Value, non-combustibility).

Proposed services

The LNE Laboratory is capable of proposing various services, including:

  • Stiff material "M" ranking,
  • Flexible material "M" ranking,
  • Euroclass SBI ranking tests,
  • Euroclass floor ranking tests,
  • Non-combustibility performance,
  • Ignitability tests,
  • Tests to determine the Higher Heating Value,
  • Full-scale test for LEPIR II facade systems.

Resources available

In response to client demand, we are able to deploy the following equipment:
