FIRE BEHAVIOR AGREEMENT

FIRE BEHAVIOR AGREEMENT

The European standard (EN 45545-2) and the French standard (NF F16-101) provide a classification system that specifies requirements for fire behavior of railway materials and products by categorizing them in different groups which have to fulfill specific “requirement sets”. The standards also include test methods for laboratories.

Moreover, the EN ISO/CEI 17025 “General requirements for the competence of testing and calibration laboratories” standard imposes the participation of laboratories in a test campaign, which is a prerequisite to be an accredited laboratory. It is on this basis that an independent body has to organize the campaign and only CERTIFER is authorized to organize and assess the fire behavior test campaigns and inter-laboratory comparison in the railway fields.

We organizes for more than ten years an annual “inter-laboratory euro-comparison campaign on railway fire behavior tests”.
This campaign is available to all laboratories that are interested in providing their laboratory services in the railway sector. About 30-40 laboratories from Europe and around the world participate each year to the euro-comparison campaign.

The steps we oversee for the euro-comparison campaign are :

  1. Preparation of the campaign
  2. Launching of the annual campaign 
  3. Test performance
  4. Compilation of results and analysis 
  5. Final reporting
