SPRINKLER RULES &
STANDARDS IN EUROPE

Development of sprinkler
rules & standards in Europe.
Overview of past, existing and

Development of sprinkler rules & standards in Europe.
Overview of past, existing and future situation
4 The first sprinkler rules appeared in years 1898 and were mainly
based on manufacturer design approach.
4 Until the years 1970’s, the most updated specifications were
developed by insurers (APSAD in France, VdS in Germany, LPC
in UK…).
4 From 1970’s most of national standardisation bodies copied the
sprinkler installation rules developed by insurers, but insurance
rules were more up to date and were very commonly used.

4
4 Until the years 1990’s: As many standards and rules (insurance
rules) as countries in Europe:
4 Even if insurers and certification bodies started to work
together on draft for common European standards and rules.

5
Why we have both insurance sprinkler rules and sprinkler
standards at the same time?
4 Standard : Public document. Usually linked to regulation for
fire protection (shopping centre, high rise building…)
4 Insurance rule : Private rules. Usually linked to insurer
recommendation (industry, warehouses…).
Scope and content are similar, but insurance rule more up to date
with some additional specifications. Insurers wish to manage their
own specifications.

12845: 2004 + Amendment N°2
edition 2009
Fixed firefighting systems.
Automatic sprinkler systems.
Design, installation and
maintenance.

EN 12 845 : background
42004: first publication of a European sprinkler installation
standard : EN 12 845 (EN = European Norm).
42009: Amendment A1 and Amendment A2.
Amendment A1
 Mainly editorial modifications
 Deletion of Annex ZA: no more kit. No more harmonised standard.
Amendment A2
 19 urgent technical modifications to make the standard more practical
(applicable): New definitions, completed table 4 (storage height), modified
table 14 (NPSH), important modification for classification of goods and
activities (influence of plastics)…

8
4This standard replace (compulsory) all the existing sprinkler
installation standards in the 27 European countries + affiliated
countries (Norway, Switzerland, Iceland).
4In each country the standard has the same numbering.
BS EN 12845 in UK
DIN EN 12845 in GERMANY
NF EN 12845 in FRANCE
UNE EN 12845 in SPAIN
…

EN 12 845 : technical content
4 Introduction reminds that the protection shall cover the entire
building (or limited by fire resistant wall - 1h minimum) with only
limited exceptions.
4 Standard to be used by competent contractors but no notion of
certification. It is up to each country.
4 The sprinklers which can be used are those defined in EN 12259-1
(maxi K115 today) but the annex L opens the possibility to other
technologies not yet covered by the standard.
4 The standard EN 12845 covers :
― Classification, ― Routines test,
― Design, ― Maintenance,
― Water supply, ― Extension
― Installation, ― Special hazards.

10
4Classification of occupancies and fire hazards
4The list of classification is given in the annex A for a direct
reading.
4Many modifications (hardening) of classification with the
amendment A2. Classifications get closer to NFPA 13.

11
Classification of occupancies and fire hazards

12
Storage - Methodology

13
Example:
Refrigerator on a plastic pallet.
Pallet : 5 kg
Fridge made of steel : total 35kg with
3kg of plastic.
Volume 1,2m3
Foam plastic insulation:0,2m3
If plastic pallet HHS3,
if wood pallet HHS2

14
Hydraulic design criteria

15
Hydraulic design criteria (A2)

16
Type of water supplies
4 Single water supply: one pump + one tank
4 Single superior water supply: Two pumps and one tank
4 Duplicate water supply: Two pumps and two tanks.
But no guideline to choose the type of water supply: up to each
national regulation.

17
Spacing and location of sprinklers
4 Area covered per sprinkler and similar spacing to the NFPA 13.

18
Maintenance
4Spare parts: 6 / 24 / 36 spk like NFPA 13.
4Weekly routine tests:
 Levels of tanks, position of valves,
 Pressure
 Water motor alarm test
 Automatic pump starting test
& run for 20 minutes.
4Monthly, quarterly, half-yearly and yearly routine test and control
defined for each equipment: similar to NFPA 25.

19
Annex G : Protection of special hazards
4 G2: aerosol: according to height and type: minimum 12,5 l/m2/min
over 260m².
4 G3 clothes on hangers: 7,5 l/m2/min + intermediate protection.
4 G4: flammable liquids: according to height and flash point
10 l/m2/min, 12,5 l/m2/min or 25 l/m2/min, but important area of
application 450 m2.

12 259-1 to 12:
sprinkler components standards

21
EN 12 259 : component standards
4 This series of standards covers the requirements and test
methods for components used in sprinkler systems.
 Part 1 – Sprinklers
 Part 2 – Wet alarm valves
 Part 3 – Dry alarm valves
 Part 4 – Water Motor Alarms
 Part 5 – Water Flow Detectors
 Part 6 – Pipe Couplings
Not yet published.
 Part 7 – Pipe Hangers
Not published. Basic requirement will be introduced into
12845.

22
 Part 8 – Pressure Switches
Not yet published.
 Part 9 – Deluge Valves
In process to be published
 Part 10 – Multiple controls
Withdrawn from the CEN list due to very limited
applications.
 Part 11 – Medium and High Velocity Watersprayers
The Components Panel has asked for this document to be
withdrawn from the CEN list due to a wide range of
variables which are manufacturer specific.
 Part 12 - Sprinkler Pumps
In process to be published

23
4 All the components shall be approved and CE marked.

CEA 4001
sprinkler systems:
planning and installation

25
4 In 1996, first publication of a European sprinkler installation
rule: The CEA 4001 (CEA = Committee of European Insurers).
4 Step by step each country is modifying its national insurance
sprinkler rule to stick toCEA rule.
4 Includes specific insurance requirements and updated regularly
(every 2-3 years).
4 Except some national specificities, all insurance rules are very
similar.

CEA 4001 : focus on some technical aspects
CEA 4001 : background

26
4New annex K11: Protection of rubber tyres
Based on full scale fire tests conducted at UL and CNPP.
Solution with spray sprinklers

27
4New annex K11: Protection of rubber tyres
 Based on full scale fire tests conducted at UL (USA) and CNPP (France).
 Solution with ESFR sprinklers

28
4 Pre-calculated system: not allowed anymore for new systems.
4 Guideline to choose the type of water supply : according to
category of risk and number of sprinklers installed: Duplicate
water supply for large site.
4 Annex with specifications for ESFR system: similar design to
NFPA 13.

29
4New concept for rack protection:
 In order to give more details about the in-rack protection and
guidance for the protection of various type of racks especially
multiple row racks, new definitions are proposed as well as
important modifications of clauses 6.2.3.3 and 11.5.

30
Conclusion
European rule and standard are on the way to be unified with less
and less technical differences between each.
Not perfect but pragmatic specifications.
… If we could avoid that, it would be good!
