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 12259-14, the residential
sprinkler component standard
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)
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 900-1
• CEA residential annex (never published)
• NFPA 13R and 13D
• And suggestions from committee members!
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
Not in the standard!
Structure of the Draft
Standard

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
900-1 no limit
 Limit in BS 9251 overruled by British regulator:
“Fire does not know it is on the 15th storey”
Some open issues – Design

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 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
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
