4.5.2 Water distribution
4.5.2.1 Water distribution test – Horizontal surface
When installed in accordance with the installation instructions and tested as described in C.1 a

residential sprinkler shall distribute water in a uniform manner over vertical surfaces as follows:
a) walls within the coverage area shall be completely wetted to at least within 711 mm of the ceiling
with one sprinkler discharging water at the specified design flow rate;
b) for square coverage areas, each wall within the coverage area shall be wetted with at least 5 % of
the sprinkler flow; for rectangular coverage areas, each wall within the coverage area shall be
wetted with a proportional water amount based on 20 % of the total sprinkler discharge in
accordance with the following formula
WW – 20 % (D / P) (2)
where
WW is required amount of water collected on a wall, in %;
D is wall length, in m;
P is total perimeter of coverage area, in m.
4.5.3 Water Impingement Test
When tested in accordance with Annex C and while discharging water at a service pressure of 5,2 bar
less than the maximum operating pressure, a residential sprinkler shall not prevent the operation of an
adjacent residential sprinkler.
4.6 Function
When tested in accordance with Annex E each of the residential sprinklers shall operate at service
pressures of 0,5 bar to the maximum operating pressure. The sprinkler shall open and within 5 s of
release of the thermally sensitive element shall operate satisfactorily. Any lodgement of released parts
shall be cleared within 60 s of the release of the thermally sensitive element. After testing in accordance
with Annex E the sprinkler shall conform to the requirements of 4.5.2.
NOTE In most instances visual examination of the equipment will be sufficient to establish conformity with the
requirements of 4.5.2.
4.7 Fire Test
When fire tested as described in Annex D a residential sprinkler shall limit temperatures as specified
below when tested at each spacing referenced in the installation instructions. Additionally, a maximum
of two residential sprinklers shall operate and the third sprinkler, located near the 1 000 mm wide
doorway, shall not operate. The sprinklers shall limit temperatures as follows:
a) The maximum temperature measured 76 mm below the ceiling at locations 4 and 5 as illustrated in
Figure D.1, Figure D.2 and Figure D.3 shall not exceed 316 °C.
b) The maximum temperature measured 1,6 m above the floor at location 4 shall not exceed 93 °C.
c) The temperature at the location described in (b) shall not exceed 54 °C for more than any
continuous 2 min period.
d) The maximum ceiling material temperature measured 6 mm behind the finished ceiling surface
shall not exceed 260 °C.
NOTE The thermocouple 76 mm below the ceiling, located above the fire source, is for reference purposes
only.

EN 12259-14:2020は、固定消防システムにおける住宅用スプリンクラーの構成要素に関する基準であり、住宅アプリケーションのためのスプリンクラーの製造と性能に関する要件を明確に定義しています。この基準の範囲は、自動スプリンクラーシステムとして使用されるスプリンクラーの動作原理に基づいており、熱の影響を受けた要素の状態変化またはガラス球の破裂によって作動します。特に、家庭や居住用の用途に特化しており、EN 16925で定義された基準を踏まえた内容です。 この標準の強みは、住宅用スプリンクラーの試験方法とタイプ承認のための具体的な指針を提供している点です。これにより、製品の設計者や製造者が高い安全基準を維持しつつ、効率的にスプリンクラーを開発できる環境が整います。また、データの圧力測定がすべてバールのゲージ圧として示されていることから、設計者は実際の運用条件に基づいた正確な計算を行うことが可能です。 ただし、本標準は特定の火災危険に対処するための特殊スプリンクラーに関する試験や、商業用および産業用スプリンクラーシステムに関する試験はカバーしていないため、注意が必要です。これらの要件は、EN 12259-1において別途定義されています。 総じて、EN 12259-14:2020は住宅用スプリンクラーシステムの設計と実施において非常に重要な標準であり、信頼性の高い消防システムの構築に寄与します。住宅や居住用アプリケーションに特化した内容であるため、関連する分野での実用性は高いといえます。
La norme EN 12259-14:2020 se concentre sur les systèmes d'extinction incendie fixes, spécifiquement sur les composants destinés aux systèmes de gicleurs et de pulvérisation d'eau, en mettant l'accent sur les gicleurs pour applications résidentielles. Cette norme définit les exigences de construction et de performance des gicleurs résidentiels et les méthodes d'essai pour leur approbation de type. L'un des points forts de cette norme est sa clarté dans la définition des exigences techniques à respecter pour garantir la sécurité dans les applications domestiques. En se basant sur un changement d'état d'un élément ou la rupture d'une ampoule en verre sous l'effet de la chaleur, elle assure que les dispositifs de sprinklage fonctionnent de manière efficace et rapide en cas d'incendie. De plus, la norme précise qu'elle s'applique uniquement aux systèmes automatiques de gicleurs pour les applications domestiques, évitant ainsi les ambiguïtés liées à d'autres types de systèmes. La pertinence de la norme EN 12259-14:2020 est renforcée par son lien avec d'autres normes, telles que EN 16925 et EN 12845, offrant ainsi une approche harmonisée de la sécurité incendie dans les contextes résidentiels. Il est également à noter que les données de pression sont spécifiées en tant que pressions manométriques en bar, ce qui facilite la compréhension et l'application des exigences techniques pour les fabricants et les installateurs de systèmes de sprinklage. Cependant, il est important de souligner que la norme ne couvre pas certains tests représentatifs pour des gicleurs spéciaux destinés à des risques d'incendie spécifiques, ni les gicleurs pour systèmes commerciaux et industriels, ce qui pourrait limiter son application dans des contextes variés. Cela est compensé par la référence à EN 12259-1 pour les exigences concernant les tests de ces autres types de systèmes. En résumé, la norme SIST EN 12259-14:2020 se révèle être un document fondamental pour les fabricants et les professionnels de la sécurité incendie, consolidant ainsi les bases de la sécurité dans les installations domestiques grâce à des critères bien définis de performance et de construction des gicleurs.
Die Norm EN 12259-14:2020 legt spezifische Anforderungen an die Konstruktion und Leistung von Sprinklern für Wohnanwendungen fest, sowie die Prüfmethoden für deren Typgenehmigung. Diese Norm bezieht sich ausschließlich auf automatisierte Sprinklersysteme, die in häuslichen und wohnlichen Anwendungen eingesetzt werden, und definiert die grundlegenden Merkmale, die diese Sicherheitssysteme erfüllen müssen. Ein zentraler Stärke der EN 12259-14:2020 ist die detaillierte Beschreibung der Wirkungsweise von Sprinklern, die durch einen Zustandswechsel eines Elements oder das Zerbrechen einer Glasbirne unter dem Einfluss von Hitze aktiviert werden.

The EN 12259-14:2020 standard is a significant document in the realm of fire safety, specifically designed for fixed firefighting systems utilized in residential applications. The scope of this standard is clearly defined, establishing essential requirements for the construction and performance of residential sprinklers. This focus on sprinklers ensures that these critical components of fire safety are effectively evaluated and operated in environments typical of domestic and residential settings. One of the primary strengths of EN 12259-14:2020 is its specification of test methods for type approval, which are crucial for ensuring that residential sprinklers respond properly to heat stimuli. The document emphasizes the importance of the construction quality and performance standards necessary for sprinklers, thus enhancing their reliability in real-world scenarios. By focusing only on automatic sprinkler systems for residential applications, this standard provides targeted guidelines that meet the unique challenges faced in domestic environments. Furthermore, while EN 12259-14:2020 establishes comprehensive guidelines for residential sprinklers, it importantly distinguishes itself by not covering special fire hazard tests or sprinklers intended for commercial and industrial systems. Instead, those requirements are addressed in EN 12259-1 and EN 12845, allowing users to easily identify which standards apply to specific scenarios. This separation of standards aids in clarity and helps manufacturers and safety professionals ensure compliance with the correct regulations for their respective applications. The standard also includes valuable notes clarifying that all pressure data is presented as gauge pressures in bar, and highlights that sprinklers according to EN 12259-1 can also be utilized for residential purposes, provided the overall system is designed according to EN 12845. This flexibility enhances the applicability of the guidelines to a broader range of systems while still maintaining a specific focus on residential safety. In summary, the EN 12259-14:2020 standard is vital for establishing effective safety measures in residential firefighting systems. By setting clear expectations for sprinkler construction, performance, and testing, it directly contributes to improved fire safety in domestic settings, offering peace of mind to homeowners and fire safety professionals alike.
