European foreword
This document (prEN 12259-15:2023) has been prepared by Technical Committee CEN/TC 191 “Fixed
firefighting systems”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
EN 12259, Fixed firefighting systems - Components for sprinkler and water spray systems, consists of the
following parts:
— Part 1: Sprinklers;
— Part 2: Wet alarm valve assemblies;
— Part 3: Dry alarm valve assemblies;
— Part 4: Water motor alarms;
— Part 5: Water flow detectors;
— Part 9: Deluge alarm valves;
— Part 12: Pumps;
— Part 13: ESFR sprinklers;
— Part 14: Sprinklers for residential applications.
Introduction
The response characteristics of classic sprinklers (EN 12259-1 and EN 12259-15) is based on the
measurement of both sensitivity and conductivity (C-factor). For EN 12259-13 sprinkler type (ESFR)
their response characteristics are determined without reference to its conductivity.
1 Scope
This document specifies requirements and test methods for spray pattern sprinklers with a k-factor of at
least K160, extended coverage (EC) sprinklers of at least K80, extended coverage storage (ECS) sprinklers
of at least K200 and control mode special application (CMSA) sprinklers of all k-factors.
This document does not apply to concealed, conventional, flat spray, flush and recessed sprinklers.

sprinkler with a k-factor of 80 to 200 intended to be installed in accordance with EN 12845-1 to protect
non-storage occupancies
3.2
extended coverage storage sprinkler
sprinkler with a k-factor of 200 and larger and intended to be installed in accordance with EN 12845-2
to protect storage occupancies
As impacted by EN 12259-1:1999+A1:2001/A2:2004 and EN 12259-1:1999+A1:2001/A3:2006.

4 Assessment methods and criteria
4.1 Tolerances
If not given differently in the specific clause below, the tolerances of Annex A shall be applied.
4.2 Connections
4.2.1 Assessment method
The sprinkler connection, e.g. the thread size, shall be assessed by measurements.
4.2.2 Criteria
The thread connections of the sprinkler shall be in accordance with ISO 7-1 or shall be grooved
connections. Alternative connection methods that have been tested and validated for use in fire sprinkler
systems also fulfil 4.2.2.
4.3 Durability of coated sprinklers
4.3.1 Assessment method
Expose 12 coated sprinklers for a period of 90 days in an oven at a temperature of 30 °C below the
nominal operating temperature. At intervals of 7 days, remove the sprinklers from the oven, allow to cool
for 2 h to 4 h and inspect the coating with the unaided eye, corrected for normal vision if necessary.
Return the sprinklers to the oven. At the end of the exposure period, remove the sprinklers from the oven,
cool them again and re-examine the coating.
4.3.2 Criteria
The coating shall show no visible evidence of damage.
4.4 High temperature exposure
4.4.1 Assessment method
The assessment method given in EN 12259-1:1999+A1:2001, Annex O shall be applied.
4.4.2 Criteria
