Fixed firefighting systems - Components for sprinkler and water spray systems - Part 14: Sprinklers for residential applications
This document specifies requirements for the construction and performance of residential sprinklers as well as test methods for their type approval, which are operated by a change of state of an element or bursting of a glass bulb under the influence of heat, for use only in automatic sprinkler systems for domestic and residential applications as defined in EN 16925:− .
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 1 All pressure data in this European Standard are given as gauge pressures in bar.
NOTE 2 Sprinklers according to EN12259-1 can also be used in residential and domestic applications if the system is designed according to EN 12845.
Ortsfeste Löschanlagen - Bauteile für Sprinkler- und Sprühwasseranlagen - Teil 14: Sprinkler für die Anwendung im Wohnbereich
Dieses Dokument legt Anforderungen an die Konstruktion und Leistung von Wohnraumsprinklern für die ausschließliche Verwendung in automatischen Sprinkleranlagen für den Wohn- und Hausgebrauch, wie nach EN 16925: ) festgelegt, die dadurch öffnen, dass sich bei Erwärmung der Zustand eines Elements ändert oder ein Glasfass zerspringt, sowie an Prüfverfahren für ihre Typgenehmigung fest.
Diese Norm gilt weder für repräsentative Brand- und andere Prüfungen für spezielle Sprinkler, die für besondere Brandgefahren vorgesehen sind, noch für Brand- und andere Prüfungen für Sprinkler für handelsübliche und industrielle Sprinkleranlagen nach EN 12845. Diese Prüfanforderungen sind durch EN 12259 1 abgedeckt.
ANMERKUNG 1 Alle Drücke in dieser Europäischen Norm werden als Überdrücke gegenüber Atmosphäre in bar angegeben.
ANMERKUNG 2 Sprinkler nach EN 12259 1 können auch für den Wohn- und Hausgebrauch eingesetzt werden, wenn die Anlage nach EN 12845 ausgelegt ist.
Installations fixes de lutte contre l’incendie - Composants des systèmes d’extinction du type sprinkleur et à pulvérisation d’eau - Partie 14: Sprinkleurs pour applications résidentielles
Le présent document spécifie les exigences relatives à la construction et aux performances des sprinkleurs résidentiels, ainsi que les méthodes d’essai en vue de leur homologation de type, ces sprinkleurs étant déclenchés par un changement d’état d’un élément ou l’éclatement d’une ampoule de verre sous l’effet de la chaleur. Ces exigences et méthodes d’essai s’appliquent uniquement aux systèmes d’extinction automatique de type sprinkleurs à usage domestique et résidentiel, tels que définis dans l’EN 16925 ).
La présente norme ne couvre ni les essais au feu et autres essais représentatifs des sprinkleurs spéciaux destinés à prévenir des risques d’incendie particuliers, ni les essais au feu et autres essais des sprinkleurs des systèmes d’extinction de type sprinkleurs à usages commerciaux et industriels spécifiés dans l’EN 12845. Ces exigences d’essai sont traitées dans l’EN 12259-1.
NOTE 1 Toutes les valeurs de pression manométrique figurant dans la présente Norme européenne sont exprimées en bar.
NOTE 2 Les sprinkleurs conformes à l’EN 12259-1 peuvent également être utilisés dans les applications résidentielles et domestiques, à condition que le système soit conçu conformément à l’EN 12845.
Vgrajene naprave za gašenje - Sestavni deli sprinklerskih sistemov in sistemov s pršečo vodo - 14. del: Sprinklerji za uporabo v stanovanjih
Ta dokument določa zahteve za konstrukcijo in izvedbo ter preskusne metode za tipsko odobritev sprinklerjev za uporabo v stanovanjih, ki delujejo po načelu spremembe stanja elementa oziroma razbitja steklenega mehurčka pod vplivom toplote. Sprinklerji so namenjeni za uporabo samo v avtomatskih sprinklerskih sistemih za bivalne površine, kot je opredeljeno v standardu EN 16925.
Standard ne zajema reprezentativnih protipožarnih in drugih preskusov za posebne sprinklerje, namenjene preprečevanju določenih nevarnosti požara, niti požarnih in drugih preskusov za sprinklerje za uporabo v komercialnih in industrijskih sprinklerskih sistemih, kot je opredeljeno v standardu EN 12845. Ti preskusi so zajeti v standardu EN 12259-1.
OPOMBA 1: Vsi podatki o tlaku v tem evropskem standardu so podani kot tlačne vrednosti merilnika v barih.
OPOMBA 2: Sprinklerje iz standarda EN 12259-1 je mogoče za bivalne površine uporabljati tudi, če je sistem zasnovan v skladu s standardom EN 12845.

1 Scope
This document specifies requirements for the construction and performance of residential sprinklers as
well as test methods for their type approval, which are operated by a change of state of an element or
bursting of a glass bulb under the influence of heat, for use only in automatic sprinkler systems for
domestic and residential applications as defined in EN 16925.
This document 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 1 All pressure data in this document are given as gauge pressures in bar.
NOTE 2 Sprinklers according to EN 12259-1 can also be used in residential and domestic applications if the
system is designed according to EN 12845.

European foreword
This document (prEN 12259-14:2018) 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.
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);
— hydrant and hose reel systems (EN 671);
— smoke and heat control systems (EN 12101).

1 Scope
This document specifies requirements for the construction and performance of residential sprinklers as
well as test methods for their type approval, which are operated by a change of state of an element or
bursting of a glass bulb under the influence of heat, for use only in automatic sprinkler systems for
1
domestic and residential applications as defined in EN 16925:− .
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 1 All pressure data in this European Standard are given as gauge pressures in bar.
NOTE 2 Sprinklers according to EN12259-1 can also be used in residential and domestic applications if the
system is designed according to EN 12845.

3.1
concealed sprinkler
unit (pre-assembled or assembled on site) consisting of a sprinkler, a housing and a cover plate, that
ensures that the sprinkler will be installed with all or part of the thermally sensitive element behind the
plane of the ceiling
3.2
recessed sprinkler
unit (pre-assembled or assembled on site) consisting of a sprinkler and a housing, that ensures that the
sprinkler will be installed with all or part of the thermally sensitive element above the plane of the
ceiling
3.3
discharge coefficient “K”
known as K-factor
coefficient of discharge in the formula,
Q = K √ p (1)
where
Q is the flow in litres per minute, and
p is the pressure in bar
3.4
dry-type sprinkler
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
3.5
flush sprinkler
unit consisting of a sprinkler and housing, that ensures that the sprinkler will be installed partly behind,
but with the temperature sensitive element before, the finished plane of the ceiling or wall
3.6
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
heptane
commercial grade heptane having the following characteristics:
a) minimum Initial Boiling Point of 88 °C;
b) maximum Dry Point of 100 °C; and
c) specific Gravity (15,6 °C/15,6 °C) of 0,68 - 0,73
3.8
orifice
opening that controls the amount of water discharged from a sprinkler at a given pressure
