  7. The Need for a European Standard

  8. We need a standard to support this Sprinkler

  9. And this!

  10. Why do we need a standard? • We are campaigning for sprinklers to be required in high-risk residential buildings, such as care homes • Fire safety regulators want a national standard as a reference – they will not accept NFPA 13R or 13D • Many officials believe that sprinklers are too expensive for housing and are unaware of residential systems • A national residential system standard would advance the national debate and national campaigns • It would complement prEN 12259-14, the residential sprinkler component standard

  11. Some countries have a standard! 2000: UK – DD 251 2004: France – CNPP Code of Practice (not a standard) 2005: UK – BS 9251 (replaced DD 251) 2005: Netherlands – Memorandum 59 2009: Nordic – INSTA 900-1 2013: Germany – VdS 2896 Code of Practice 2014: Netherlands – NEN 2077 (replaced Memo 59)

  12. But… • Most countries do not have a national standard • Some of these national standards have good ideas that others could use • Some have clauses that significantly increase costs • Working together, we can produce a European standard that brings together our best ideas • CEN standards automatically become national standards

  13. Input Sources and Activity to Date

  14. Input Sources • BS 9251 • INSTA 900-1 • CEA residential annex (never published) • NFPA 13R and 13D • And suggestions from committee members!

  15. Activity to Date • Working off INSTA 900-1 since in CEN format • Held five meetings with 10-18 participants and 5-10 countries represented • Addressed differences between INSTA 900-1, BS 9251 and CEA draft • Included committee learning from field, research on anti-freeze, proposed changes to INSTA 900-1, BS 9251, NFPA 13R and 13D

  16. Not in the standard!

  17. Structure of the Draft Standard

  18. Structure of the Draft Standard • Foreword with background to residential sprinklers • Introduction with P&IDs to show the concept • Scope (as agreed with CEN for EN 12845)

  19. Scope • Building type 1 (the least hazardous) • One or 2 family dwelling / house • Single apartment in an unsprinklered building • Manufactured home • Building type 2 • Apartments / block of flats • House with multiple households using shared facilities • Care home / nursing home (excluding hospitals) / kindergarten • Student accommodation • Building type 2 is limited to buildings with up to 4 storeys above ground • Building type 3 • Building type 2 higher than 4 storeysand hotels up to 4 storeys

  20. Structure of the Draft Standard • Foreword with background to residential sprinklers • Introduction with P&IDs to show the concept • Scope (as agreed with CEN for EN 12845) • Normative references • Terms & definitions • Contract planning & documentation • Extent of sprinkler protection

  21. Extent of sprinkler protection • Areas not requiring sprinklers: • bathrooms < 5 m2(no combustibles, washing machines) • normally unoccupied attics • shadow areas • normally unoccupied rooms • open balconies/corridors/stairs/porches; • crawl spaces • enclosed vertical shafts

  22. Structure of the Draft Standard • Foreword with background to residential sprinklers • Introduction with P&IDs to show the concept • Scope (as agreed with CEN for EN 12845) • Normative references • Terms & definitions • Contract planning & documentation • Extent of sprinkler protection • Hydraulic design and pipe layout • Water supplies • Type of Water Supply

  23. Structure of the Draft Standard, contd. • Pumps • Installation type and size • Spacing and location of sprinklers • Sprinkler design characteristics and uses • Valves • Alarms and alarm devices • Pipe work • Signs, notices and information • Commissioning and acceptance tests • Inspection, testing and maintenance

  24. Structure of the Draft Standard, contd. • Annex A (informative) Zoning • Annex B (normative) Sprinkler systems monitoring • Annex C (normative) Transmission of alarms • Annex D (informative) Precautions and procedures when a system is not fully operational • Annex E (informative) Inspection of pipes and sprinklers • Annex F (informative) New technology

  25. Some open issues and next steps

  26. Some open issues – General • European standard, technical specification or technical report (EN, TS or TR)? • Only a standard will be accepted in the market and by officials as a reference • Several countries have experience with national standards, the technology is mature so we are ready to prepare a European standard

  27. Some open issues – Scope • Area limit for Type 2 (care homes to 4 storeys)? • No area limit in BS 9251, INSTA 900-1, NFPA 13R • Height limit for Type 3 (apartments > 4 storeys)? • BS 9251 – 20m; NFPA 13R – 4 storeys but INSTA 900-1 no limit • Limit in BS 9251 overruled by British regulator: “Fire does not know it is on the 15th storey”

  28. Some open issues – Design Should density be greater for Type 2 and Type 3? Number of design sprinklers for Type 2 and Type 3?

  29. Some more open issues • Are the pump requirements too onerous? • Mainly from EN 12845 – chapter needs work • Do we allow dry systems and anti-freeze? • They are in the draft but dry systems are vulnerable to corrosion and anti-freeze is combustible • Yet there are ways round both problems

  30. Next steps • Send the draft for enquiry (comments) late 2014 • We may work on it a little more first • Work through comments in 2015 and send for vote late 2015 • Publication autumn 2016 (I hope!)
