Fire behaviour tests


We provide tests in the development phase or in the operational phase of your products:
  • Product and equipment designers must incorporate the risks of fire or explosion in the development phase
  • Safety managers need to know the fire behaviour of certain appliances during operation.


We provide an appropriate answer to your need:
 
  • By implementing fire behaviour tests in accordance with the currently applicable standards
  • By carrying out tests according to your test protocol

Examples of tests
  • ·Steel tray insulating cover
When the Co2 ranking of the roof cannot be automatically obtained, for example, because of a heat value higher than the required value in the D14 document, the latter allows for a full-scale ranking test.
We instrument a test model using 17 thermocouples. If at the end of the test, the roof satisfies the test criteria of D14, Co2 ranking can be obtained.
 
  • Aircraft equipment
Standards have been developed to guarantee a certain level of fire resistance in the materials used in aircraft. Against this background, we perform the following tests:
-    Fire resistance of materials according to the standards FAR/JAR 25 Appendix F and RTCA/DO-160E Section 26
-    Fire resistance of on-board equipment in "fire zone" designated areas according to the ISO 2685 standard.
 
  • Tests on safes
The manufacturers of safes develop and design safes to resist vandalism and attacks using solid or gaseous explosives.
We carry out tests for EX or GAS ranking, in compliance with European standard EN 1143-1.
-    “EX” tests: Implementation of an explosive charge (Pentrite) in the centre of the internal volume of the safe following by a post-blast attack with tools.
-    “GAS” tests: Implementation of an explosive charge (flammable gaseous mixture consisting of oxygen and acetylene) in the centre of the internal volume of the safe following by a post-blast attack with tools.
  
  • Fire resistance tests of smoke control fire shutters and dampers
Whatever the mode of use of a smoke damper, we test its fire resistance:
-    Damper integrated with a horizontal wall (floor-type application) or vertical (wall-type application), a cubic oven of 27 m3, maximum 3mx3mx3m.
-    Damper mounted on a ventilation duct
Single-compartment smoke damper
-    Tightness test according to EN 1751 on the smallest and largest damper
-    Cycling test on the largest fire shutter
-    High temperature test on the largest fire shutter: preliminary tightness test at room temperature. Then monitoring of the standard temperature increase curve up to a level specified prior to the test.
Multi-compartment smoke damper
1) "HOT" Classification with damper initially open
-    Tightness and fire resistance tests in accordance with EN 1366-2
-    Testing at standby temperature for 72 hours (trigger in an isolated enclosure)
-    HOT 400/30 Test
2) On the side of a compartment structure with the damper initially open or closed.
-    Tightness test according to EN 1751 on the smallest and largest damper
-    Cycling test on the largest fire shutter
-    Tightness and fire resistance tests in accordance with EN 1366-2
3) On the surface of a vertical or horizontal duct
-    Test identical to that for single-compartment dampers
