Understanding EN Regulations for Fire Duct and Ductwork

Understanding EN Regulations

European Standards (ENs) are documents that have been ratified by one of the three European Standardisation Organisations ESOs, CEN, CENELEC or ETSI; recognised as competent in the area of voluntary technical standardisation, EU Regulation 1025/2012.

An EN European Standard:

carries with it the obligation to be implemented at national level by being given the status of a national standard and by withdrawal of any conflicting national standard".

Therefore, a European Standard automatically becomes a national standard in each of the 34 CEN-CENELEC member countries.

When it pertains to smoke extract, a harmonised standard hEN 12101-7 was released with a transition period ending July 2013. From July 2013, all smoke extract must comply with the standard EN 12101-7, and be classified to EN standard 13501-4. The appropriate tests are, multi-compartment EN 1366-8 and single-compartment EN 1366-9. In keeping with the requirements of the Construction Products Directive, all smoke extract must carry the CE symbol.

From July 2013, all smoke extract must comply with the standard EN 12101-7, and be classified to EN standard 13501-4.

Fire rated ducts, other than smoke applications, are subject to the test standard EN 1366-1, which became national standard in April 2015. The classification report for fire ducts is EN 13501-3. A harmonised standard is still being ratified, and until such time as it is adopted, fire ducts with the exception of smoke ducts, do not require a CE marking.

Fire tests are conducted with

  • Mechanical and dynamic pressure
  • Leakage measurements
  • Cross sectional area movements
  • Different orientations
  • Hydrocarbon fire curve
  • Fire types A and B and C

Ducts are classified as

  • E Integrity
  • I Insulation
  • S leakage
  • Type A o -> i
  • Type B I -> o
  • Minutes (15,30,45,60,90,120)
