Ortsfeste Brandbekämpfungsanlagen - Bauteile für Sprinkler- und Sprühwasseranlagen - Teil 14: Sprinkler für die Anwendung im Wohnbereich

Diese Europäische Norm legt Anforderungen an den Bau und die Leistungsmerkmale von Sprinklern für den Wohnbereich sowie ihre Rosetten fest, die für Anwendungen in automatischen Sprinkleranlagen für den Wohnbereich vorgesehen sind und dadurch betrieben werden, dass unter dem Einfluss von Wärme eine Änderung des Zustands eines Elements eintritt oder es zum Bersten eines Glasfasses kommt. Prüfverfahren und ein empfohlener Prüfplan für die Typprüfung werden ebenfalls angegeben.
Diese Norm behandelt weder repräsentative Brandprüfungen und sonstige Prüfungen für spezielle Sprinkler, die für besondere Brandgefahren vorgesehen sind, noch deckt sie Brand- und sonstige Prüfungen für Sprinkler für kommerzielle und Industrie-Sprinkleranlagen nach EN 12845 ab. Diese Prüfanforderungen werden in EN 12259 1 behandelt.
ANMERKUNG   Alle Drücke in dieser Europäischen Norm werden als Überdrücke gegenüber Atmosphäre in bar angegeben.

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

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.
