6. Agenda The Need for a European Standard Input Sources and Activity to Date Structure of the Draft Standard Some Open Issues and Next Steps

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.  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 storeys and 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

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 15 th storey”

28. Some open issues – Design Type of residential sprinkler system Minimum design discharge density (mm/min) Number of design sprinklers Minimum duration of water supply (minutes) 12,041-210 22,041-430 32,04430 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!)
