Overview
EN 15254-7:2018 - Extended application of results from fire resistance tests - Non-loadbearing ceilings - Part 7: Metal sandwich panel construction (CEN) defines rules and guidance for extending fire test results for internal non-loadbearing ceilings made from self‑supporting, double‑skin metal faced sandwich panels (as per EN 14509). It explains how results from an EN 1364-2 ceiling fire test can be applied to variations in materials, geometry and fixing systems to support a fire classification under EN 13501-2.
Key topics and technical requirements
- Scope and assumptions: Applies to factory made metal sandwich panels with an insulating core bonded to both facings. Assumptions include one‑side fire exposure, limited support structure deflection, and use of EN 1993‑1‑2 rules for steel strength at elevated temperature.
- Field of extended application: Differentiates direct field of application (identical conditions) from extended application (predicted performance for variations using rules and calculations).
- Material and construction variations: Rules cover changes in metal facings, adhesives and core materials, panel thickness, span length, joint design, boundary conditions and fixing systems. Example: small changes in sheet thickness may be permitted (table shows an allowed variation of ±0.2 mm of tested thickness).
- Interaction and limits: Guidance on how factor influences interact (e.g., core type vs. insulation performance) and when additional testing is required.
- Calculations and measurements: Clause 6 and Annex C provide calculation methods for extending span length, evaluating catenary forces and allowable spans under elevated temperatures; additional measurements to record in the reference test are specified.
- Annexes: Informative annexes include typical fire behaviour of sandwich panel ceilings, example end fixings, and normative calculation rules for span extension and catenary forces.
Practical applications
- Use EN 15254-7:2018 to:
- Assess whether a tested sandwich panel ceiling can be specified for different panel lengths, thicknesses or fixation layouts without repeat full-scale testing.
- Produce extended application reports for product certification, tender documentation or compliance demonstration.
- Support risk-based specification decisions for ceilings in commercial, industrial and public buildings where non‑loadbearing fire-rated ceilings are required.
Who should use this standard
- Manufacturers of metal sandwich panels and adhesive systems
- Fire engineers and laboratories conducting EN 1364-2 tests and extended application analyses
- Certifiers and approval bodies producing classification documents under EN 13501-2
- Specifiers / architects / installers who need to confirm compliance when changing panel design, span or fixing details

Extended application is a prediction of the expected fire resistance of fire resistant metal faced sandwich panels. It may be based on interpolation between or extrapolation from test data. The fundamental consideration shall be that the fire resistant metal faced sandwich panels after extension would achieve the required fire performance if it were to be tested according to EN 1364-2. The extended application of test results from metal faced sandwich panels used as a non-loadbearing ceiling shall be based on the reference fire test results performed according to EN 1364-2 and may be complemented by one or more additional tests. The general rules in EN 15725 shall be followed. SIST EN 15254-7:2018
« s r % for a new coating compared to the tested one is thus allowed if there is at least a 10 % margin in the insulation test result compared to the I-classification. Test results are always valid for coatings with higher emissivity values compared to the tested one. When a change in coating is made, the manufacturer of the coated sheet shall provide emissivity properties for the products. A non-coated metal sheet can have an emissivity as low as 0,1. A change from a coated to a non-coated sheet is therefore not allowed. The same rule specified above for coatings applies also in this case. A decrease in emissivity of 10 % is allowed if the emissivities of the different sheets are known. The energy content of

Die Norm EN 15254-7:2018 behandelt die erweiterte Anwendung von Ergebnissen aus Feuerwiderstandstests, speziell für nicht tragende Decken, die aus Metall-Sandwichpaneelen konstruiert sind. Ihr Geltungsbereich ist klar definiert und konzentriert sich auf die Regelungen und Verfahren, die für die Variation bestimmter Parameter und Faktoren im Zusammenhang mit dem Design von Innendecken relevant sind. Ein wesentlicher Vorteil dieser Norm besteht in ihrer umfassenden Anleitung für die Konstruktion von selbsttragenden, doppelschaligen Metall-Sandwichpaneelen. Diese Paneele haben einen isolierenden Kern, der gemäß EN 14509 an beiden Außenflächen angebracht ist. Die Norm gewährleistet dadurch, dass alle Aspekte des Designs berücksichtigt werden, um sicherzustellen, dass die Konstruktionen den erforderlichen Sicherheitsstandards entsprechen. Darüber hinaus ist die Norm von großer Relevanz für die Bauindustrie, da sie klare Richtlinien bietet, wie die Ergebnisse von Feuerwiderstandstests, die gemäß EN 1364-2 durchgeführt wurden, auf andere Konstruktionen angewendet werden können. Dies ermöglicht eine systematische Bewertung und Klassifizierung entsprechend EN 13501-2, was für Architekten, Ingenieure und Bauherren von entscheidender Bedeutung ist. Insgesamt stärkt die EN 15254-7:2018 die Planungssicherheit und erhöht die Brandschutzstandards für nicht tragende Decken, die mit Metall-Sandwichpaneelen konzipiert sind. Die systematische Vorgehensweise und die klare Dokumentation reduzieren potenzielle Planungsfehler und fördern die Einhaltung von Sicherheitsrichtlinien im Bauwesen.

The standard EN 15254-7:2018 offers a comprehensive framework for the extended application of results derived from fire resistance tests specifically focused on non-loadbearing ceilings constructed from metal sandwich panel construction. This document establishes essential rules and guidance aimed at ensuring consistency in evaluating variations in design parameters and factors that are pivotal to the relevant fire safety performance of such ceilings. One of the primary strengths of EN 15254-7:2018 lies in its clarity in outlining the conditions under which extended applications can be justified, thereby enhancing the reliability of classifications derived from fire resistance tests conducted following EN 1364-2. This is particularly significant in construction environments where metal faced sandwich panels are prevalent, as it enables stakeholders to implement these materials while maintaining compliance with fire safety regulations. Additionally, the standard's focus on self-supporting, double skin metal faced sandwich panels-with an insulating core bonded to both facings as detailed in EN 14509-ensures it is directly applicable to contemporary construction practices. This alignment with industry standards demonstrates the document's relevance, as it addresses the technical requirements necessary for ensuring the fire safety of non-loadbearing ceilings, a critical aspect of overall building safety. Moreover, the procedural guidance provided within EN 15254-7:2018 facilitates a thorough understanding among designers and builders regarding the implications of variations in performance metrics, thereby fostering a greater commitment to achieving the highest fire resistance standards. This not only enhances safety protocols but also contributes to the overall efficiency in the construction process by minimizing ambiguities related to material performance. Overall, EN 15254-7:2018 serves as an indispensable resource within the construction industry, ensuring that the application of metal sandwich panel technology is both effective and compliant with established fire safety benchmarks.
