Foreword
This document (prEN 12259-14:2014) 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.
Annexes A to R are normative. Annex S is informative. This document includes a Bibliography.
It is included in a series of European standards planned to cover:
 automatic sprinkler systems (EN 12259 and EN 12845);
 gas extinguishing systems (EN 12094);
 powder systems (EN 12416);
 explosion protection systems (EN 26184);
 foam systems (EN 13565);
 gas systems (EN 12094);
 hydrant and hose reel systems (EN 671);
 smoke and heat control systems (EN 12101).
1 Scope
This European standard specifies requirements for construction and performance of residential sprinklers and
their rosettes which are operated by a change of state of an element or bursting of a glass bulb under the
influence of heat, for use in automatic residential sprinkler systems. Test methods and a recommended test
schedule for type approval testing are also given.
This standard does not cover representative fire and other tests for special sprinklers that are intended to
provide for specific fire hazards, nor does it cover fire and other tests for sprinklers for commercial and
industrial sprinkler systems as in EN 12845. Those test requirements are covered by EN 12259-1.
NOTE All pressure data in this European standard are given as gauge pressures in bar.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

sprinkler secured in an extension nipple that has a seal at the inlet end to prevent water from entering the
nipple until the sprinkler operates
Note 1 to entry: These sprinklers may consist of a pendant, sidewall, ceiling or other types.
3.5
flush ceiling sprinkler
sprinkler in which all or part of the body, including the shank thread, is mounted above the lower plane of the
ceiling

heat responsive element
that portion of a sprinkler that breaks, melts, or otherwise functions to initiate the automatic operation of the
sprinkler when exposed to sufficient heat
3.7
