The Need for a European Standard

We need a standard to support this Sprinkler

And this!

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 , the residential sprinkler component standard

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

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

Input Sources and Activity to Date

Input Sources BS 9251 INSTA CEA residential annex (never published) NFPA 13R and 13D And suggestions from committee members!

Activity to Date Working off INSTA since in CEN format Held five meetings with 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

Not in the standard!

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)

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

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

Extent of sprinkler protection

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

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

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

Some open issues and next steps

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

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 no limit  Limit in BS 9251 overruled by British regulator: “Fire does not know it is on the 15 th storey”

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, , ,04430 Should density be greater for Type 2 and Type 3? Number of design sprinklers for Type 2 and Type 3?

Some more open issues Are the pump requirements too onerous?  Mainly from EN – 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

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!)

Thank you for your attention Alan Brinson
