It may be based on interpolation between or extrapolation from test data. The fundamental consideration shall be that the fire resistant glazed element after extension would achieve the required fire performance if it were to be tested according to EN 1364-1:2015. The test results are applicable to similar constructions where one or more of the changes in the direct field of application in EN 1364-1:2015 and this standard are made, and it is the manufacturer’s responsibility that the construction continues to comply with the appropriate design code for its stiffness and stability. For test reports based on an edition of EN 1364-1 earlier than 2015, the direct field of application according to EN 1364-1:2015 may be applied. An increase in the classification time (e.g. from EI 30 min to EI 45 min) and/or changes to the fire performance classification (e.g. from E to EW) achieved in the reference test shall not be permitted by the application of the extended application rules. The only exception is detailed in 7.2. The overview regarding the relevant changeable parameters for extended application for fire resistant glazed elements is given in Table 1. Extended application reports shall be prepared according to EN 15725. SIST EN 15254-4:2019

표준 EN 15254-4:2018은 비하중벽을 위한 유리 구조물의 방화 성능 테스트 결과의 확장 적용에 관한 지침을 제공하며, 관련된 설계 절차를 정의합니다. 이 문서는 EN 1364-1:2015에 따라 테스트된 방화 유리 요소에 대한 다양한 매개변수 및 요소의 변형에 대해 특정 기준을 제공합니다. 방화 유리 요소의 확장 적용은 시험 증거에 기반하고 있으며, 특히 수직으로 설치된 방화 유리 요소에만 적용됩니다. 이 표준의 강점은 방화 유리 요소의 설계 시 일관되고 체계적인 접근 방식을 제공한다는 점입니다. 방화 성능 기준에 따라 분류된 유리 요소의 검사 결과를 활용하여 적절한 설계를 할 수 있도록 돕는 데 큰 의의가 있습니다. 또한 유리에 대한 방화 성능을 평가하기 위한 기본적인 틀을 제공하므로, 건축 설계자와 엔지니어들이 보다 효율적이고 안전한 방화 유리 시스템을 구현하도록 합니다. 그러나 이 표준은 EN 1634-1에 의한 도어 세트와 열 수 있는 창에 적용되지 않으며, EN 1364-3 및 EN 1364-4에 따른 커튼 월링의 전체 구성 또는 부분 구성에도 적용되지 않습니다. 또한 EN 1051-1 및 EN 572-7에 정의된 유리 블록 조립체와 포장 유닛 및 채널형 유리는 현재 충분한 정보가 없어 확장 적용 규칙을 개발할 수 없다는 점도 명시되어 있습니다. 이러한 제한 사항은 사용자가 본 표준의 적용 범위를 정확히 이해하고 적절히 적용해야 함을 의미합니다. 결론적으로, EN 15254-4:2018 표준은 방화 유리 요소의 설계에 있어 신뢰할 수 있는 지침을 제공함으로써, 건축물의 안전성을 높이고 관련 산업의 전문성을 더욱 강화할 수 있는 중요한 역할을 합니다. 이 표준의 적절한 사용은 방화 유리 구조물의 성능을 극대화하는 데 기여할 것입니다.
The standard EN 15254-4:2018 provides a crucial framework for the extended application of results from fire resistance tests specifically related to non-loadbearing glazed constructions. This document is vital for professionals involved in the design and assessment of fire safety systems as it outlines procedures for evaluating the performance of fire resistant glazed elements tested in accordance with EN 1364-1:2015 and classified according to EN 13501-2. One of the strengths of this standard is its focus on enhancing the understanding and application of fire resistant glazed elements through detailed guidance and definitions of variations in parameters and design factors. This ensures that industry players can make informed decisions based on test evidence, promoting safety in vertically installed fire resistant glazed elements, which is its primary concern. The relevance of EN 15254-4:2018 cannot be understated as it addresses a critical need within the construction and safety sectors. It specifically provides clarity on what elements fall under its scope and highlights exclusions, such as door sets, openable windows, and curtain walling configurations. By clearly delineating the types of products covered, the standard helps practitioners avoid misapplication and ensures adherence to safety protocols. In summary, this standard not only promotes an understanding of fire resistant glazed elements but also reinforces the importance of evidence-based assessment in protecting structures from fire hazards. Its applicability to specific configurations defines a clear pathway for compliance, thereby enhancing overall safety in building designs.
La norme EN 15254-4:2018, intitulée "Application étendue des résultats des essais de résistance au feu - Murs non porteurs - Partie 4 : Constructions vitrées", offre un cadre essentiel pour la conception d'éléments vitrées résistants au feu. Son champ d'application est clairement défini, se concentrant sur les éléments en verre installés verticalement, ce qui en fait une référence importante pour les concepteurs et ingénieurs en bâtiment. Parmi ses points forts, cette norme fournit des directives précises et établit des procédures pour les variations de certains paramètres liés à la conception d'éléments en verre qui ont été testés conformément à la norme EN 1364-1:2015 et classés selon EN 13501-2. Cela permet d'assurer une cohérence dans l'application des résultats des tests de résistance au feu, favorisant ainsi la sécurité tout en offrant la flexibilité nécessaire lors de la conception. La pertinence de la norme réside dans son approche basée sur des preuves de test, garantissant que seuls les éléments ayant subi des tests rigoureux puissent bénéficier d'une application étendue. Cela renforce la confiance des professionnels de la construction dans la durabilité et l'efficacité des constructions vitrées face au feu. Il est essentiel de noter que la norme ne s'applique pas aux ensembles de portes et fenêtres ouvrantes selon EN 1634-1, ni à la configuration complète ou partielle de la façade rideau selon EN 1364-3 et EN 1364-4. De plus, les assemblages de blocs de verre et les unités de pavage, ainsi que le verre en forme de canal, comme défini dans EN 1051-1 et EN 572-7, sont exclus. Cette exclusion souligne l'importance d'une application ciblée et fondée sur des données disponibles, garantissant ainsi que les recommandations fournies ne s'appliquent qu'aux produits pour lesquels des règles fiables peuvent être établies. En conclusion, la norme EN 15254-4:2018 se présente comme un document crucial qui enrichit la compréhension des constructions vitrées résistantes au feu, tout en veillant à ce que les praticiens du secteur disposent des informations les plus pertinentes et actualisées pour leur utilisation.
Die Norm EN 15254-4:2018 behandelt die erweiterte Anwendung von Ergebnissen aus Brandprüfungen speziell für nicht tragende Wände in Form von verglasten Konstruktionen. Sie bietet wertvolle Leitlinien und definiert Verfahren zur Variation bestimmter Parameter und Faktoren, die mit dem Entwurf feuerbeständiger verglaster Elemente verbunden sind, die gemäß EN 1364-1:2015 geprüft und nach EN 13501-2 klassifiziert wurden. Ein zentrales Merkmal dieser Norm ist die Möglichkeit, auf vorhandene Prüfergebnisse zurückzugreifen, um die Sicherheit und Funktionsfähigkeit der feuerbeständigen verglasten Elemente zu gewährleisten. Die Norm konzentriert sich ausschließlich auf vertikal installierte feuerbeständige verglaste Elemente und schließt Türanlagen und öffnungsfähige Fenster in Übereinstimmung mit EN 1634-1 sowie Vorhangfassaden, sowohl in vollständiger als auch in teilweiser Konfiguration gemäß EN 1364-3 und EN 1364-4, aus. Die Stärken der EN 15254-4:2018 liegen in ihrer klaren Fokussierung auf die spezifischen Anforderungen von brennbaren Materialien und deren Anwendung im Bauwesen. Durch die klare Definition der Anwendungsbereiche und der Ausschlüsse, wie z.B. Glasblockkonstruktionen und Pflastereinheiten, wird sichergestellt, dass nur geeignete Produkte behandelt werden, was zu einer höheren Verlässlichkeit und Sicherheit in der praktischen Anwendung führt. Die Relevanz dieser Norm ist unbestritten, da sie eine wichtige Richtlinie für Architekten, Ingenieure und Bauunternehmen bereitstellt, um die Anforderungen an feuerbeständige, verglaste Konstruktionen zu erfüllen, während gleichzeitig der Schutz von Menschenleben und die Einhaltung von Vorschriften gewährleistet wird. Die Norm EN 15254-4:2018 ist somit ein unverzichtbares Dokument im Bereich des Brandschutzes für Baukonstruktionen.
SIST EN 15254-4:2019は、火災試験結果の延長適用に関する標準であり、特に非荷重壁におけるグレーズド構造に焦点を当てています。この標準は、EN 1364-1:2015に従って試験された火災に対する耐性を持つグレーズド要素の設計に関連する特定のパラメータや要因の変動に関するガイダンスを提供します。 この文書の範囲は、垂直に設置された耐火性のグレーズド要素に限定されており、ドアセットや開放可能な窓、カーテンウォールに関しては適用されません。この厳密な範囲設定は、標準の適用の明確性を保ち、デザインにおける基準が一貫して適用されることを確保しています。 SIST EN 15254-4の強みは、試験結果に基づいた耐火性グレーズド要素の拡張適用の基準を示すことで、設計者やエンジニアが安全で効果的な構造物を作成するための信頼性の高い指針を提供している点にあります。これは、現場での実用性と安全性を高める上で不可欠です。 さらに、この標準はガラスブロックアセンブリや舗装ユニット、チャンネル状ガラスを除外しているため、これらに関する延長適用ルールが十分な情報に基づいていないことを明確にしています。この点は、製品の安全性を保証するために重要です。 総じて、SIST EN 15254-4:2019は、耐火性を持つグレーズド構造における試験結果の延長適用に関する確固たる基準を確立していることから、関連業界において非常に重要であり、今後の設計基準の策定に寄与することでしょう。
