SECTION 2 : HAZARD EVALUATION
SECTION 3 : DESIGN CRITERIA
SECTION 4 : INSTALLATION
SECTION 5 : WATER SUPPLY
SECTION 6 : COMMISSIONING AND CONTROL PROGRAMME
Annexes
Draft expected S2-2014
Future revision 2 of EN 12 845 : KEY POINTS
SECTION 1: SCOPE, REFERENCES and DEFINITIONS
 Introduction enabling new technologies not included
 Scope more precise to avoid conflict especially with residential
sprinkler standard
 More comprehensive set of definitions
 Will include contract, planning and documentation
Future revision 2 of EN 12 845 : KEY POINTS
SECTION 2 : HAZARD EVALUATION
 New HHS 5 to take into account plastic goods
 Classification will differentiate: manufacturing / nonmanufacturing.
 Classification for manufacturing will include additional parameters
to define hazard :
Fire Hazard : FH1, FH2, FH3 or FH4
Will be detailed in the next presentation (Stuart Lloyd)
Future revision 2 of EN 12 845 : KEY POINTS
SECTION 3 : DESIGN CRITERIA
 Design density and area of operation linked to hazard class + ceiling
height
 Design section for storage will include existing and new protection
tables + new HHS 5 classification.
 Will cover the former special risk annex G (flammable liq, hanging
garments, aerosols...)
 Storage configuration STC1 to STC6 will remain similar as today
 ESFR and CMSA will be as separate chapters
Future revision 2 of EN 12 845 : KEY POINTS
SECTION 4 : INSTALLATION
No big modification but many improvements and precisions of
existing text :
 dry system,
 more details about specific areas like stairways, concealed spaces..
 location from beams,
 Sprinkler above suspended ceiling. 9 m² for hollow spaces > 0.3 m and < 0.5
m…,
 Clarification about location of in-rack sprinkler
 Special rack configuration included
 Corrosion issues
 Electrical issues: more details provided especially regarding alarms
Future revision 2 of EN 12 845 : KEY POINTS
SECTION 5 : WATER SUPPLY
 Connection for other service : hydrants 90m3/h in OH and 120 m3/h
in HH.
 Detailed requirements for pump room and alarm valve room
 Velocity in the suction pipe increased to 2,5 m/s for suction lift
condition and 4m/s for positive head : cost effective modification
 Specific requirements for diesel equipped with Electronic Fuel
Management Control (ECM)
Future revision 2 of EN 12 845 : KEY POINTS
Section 5 : water supply
 Volume of tank no longer based on Qmax: reduction of tank volume;
based on unfavourable area.
Future revision 2 of EN 12 845 : KEY POINTS
SECTION 6 : COMMISSIONING AND CONTROL PROGRAMME
 Contract , planning and documentation: simplification with
suppression of preliminary design stage
 Flushing of pipework
 Detail procedure for commissioning and first inspection to be be
witnessed by the authorities or a third party inspection body
accepted by the authorities
 Model of maintenance report provided : complete list of all
maintenance operation for each component
 Model of commissioning and inspection report provided
Future revision 2 of EN 12 845 : KEY POINTS
SECTION 6 : COMMISSIONING AND CONTROL PROGRAMME
 Detailed user’s control programme
Future revision 2 of EN 12 845
Annexes
All references to pre-calculated system suppressed from
main body of the text
Specific annex (stand alone) covers all the requirements
for pre-calculated system (FH1 and FH2)
Number of annexes reduced
Comprehensive annex for new technologies detailing
process to accept them
Future revision 2 of EN 12 845 : conclusion
Even if many modifications are expected:
Standard should be simple to understand and to
apply: more flow charts and graphics
Installation should not be more expensive than
today (even less: e.g. tank volume…)
A large range of technology (K factor, type of
sprinklers…) should be possible
CEA 4001- new edition 2013
First published in 1996
Latest edition August 2013
