  2. Reaction to fire classification for cables • The History • 1999 First draft mandate under CPD • 1999/2000 First Europacable proposal based on use of modified EN50266 • 2000/2001 First Commission proposal based on use of modified EN50266 • Cables 2003 Cables and the CPD – Threat or Opportunity? • 2004 Second Commission proposal based on use of FIPEC test protocols • 2006 Commission decision based on use of FIPEC test protocols

  3. Reaction to fire classification for cables • The Commission Decision • Dated 27 October 2006 • “separate classes of reaction-to –fire performance should be established for electric cables” • Add “Table 4 Classes of reaction-to –fire performance for electric cable” • Add “Mounting and fixing conditions and definitions of test parameters regarding electric cables”

  4. Table 4 Classes of reaction-to-fire performance for electric cables

  5. Footnotes to classes for reaction-to-fire performance of electric cables

  7. Reaction to fire classification for cables • Current / Future actions • Decision on Mandate • Decision on attestation of conformity • Supporting test standards, classification standards and product standards • Extended application rules • National implementation

  8. Reaction to fire classification for cables • The draft Mandate • Mandate to CEN/CENELEC concerning standardisation work for harmonised standards • Scope covers power, control and communication cables for use in buildings and other civil engineering works (all voltages included and fibre optics) • Scope covers reaction to fire, resistance to fire and dangerous substances • Agreed by EGF (Dec06) for SCC vote (Apr07)

  9. Reaction to fire classification for cables • Mandate deliverables • Test standards (EN50399) • (P classification fire resistance test under M/117) • Classification standard (EN13501-1 revision?) • Product standards • EXAP rules • Standstill applies once the Mandate is accepted

  10. Reaction to fire classification for cables • Attestation of conformity • Reaction to fire in system 1/3/4 (Class A to C in 1, Class D, E in 3, Class F in 4) • Resistance to fire in system 1 (system 1 for all classes) • Dangerous substances in system 3 • Proposed by EGF (Dec06) for SCC vote and final decision (Apr07)

  11. Reaction to fire classification for cables • Extended application (EXAP) rules • What cables to test to gain approval for a complete range • Must be agreed by Commission so needs the involvement of third party test laboratories • Europacable propose an Industry funded project with SP and other third party laboratories to establish rules

  12. Reaction to fire classification for cables • Euroclass table as a Regulatory tool • Legally only applies to products subject to regulation • Regulation is a National matter • Regulatory position on resistance to fire may be different to that on reaction to fire • Classification is a ranking which is dependent on the test parameters chosen by the EC

  18. prEN50399 Effect of Air Inlet Grid

  19. Effect of Cable Size on Classification

  20. Reaction to fire classification for cables • Conformity assessment • Need for supervision and control • Control of test facilities – sensitivity to small changes in design of test apparatus and procedures • Control of product manufacture – sensitivity to small changes in design and production process on reaction to fire performance
