Overview
prEN 15254-7 (Extended application of results from fire resistance tests - Non-loadbearing ceilings - Part 7: Metal sandwich panel construction) is a CEN draft standard that defines rules, guidance and procedures for extending fire-resistance test results for internal non‑loadbearing ceilings made from double‑skin metal‑faced sandwich panels. It specifically covers panels with an insulating core bonded to both facings (as defined in EN 14509) and applies when panels have been tested in accordance with EN 1364-2 and need a fire classification under EN 13501-2.
Key topics and technical requirements
- Field of extended application: Establishes when and how a reference fire test can be used to predict performance for variations in product properties or end‑use.
- Assumptions: Defines baseline assumptions for extensions (single‑side exposure, supporting construction stability, load transfer after facing delamination, material density and mass calculations, and strength reduction at elevated temperature per EN 1993-1-2).
- Material variations: Rules for acceptable changes in metal facings, adhesives and core materials and how these influence integrity, insulation and overall fire performance.
- Construction variations: Guidance on changes to span length, panel thickness, longitudinal joint details, fixing systems and ceiling dimensions - including limits and when calculation or additional testing is required.
- Interaction of factors: Addresses combined effects when multiple parameters change simultaneously.
- Support structure and fixings: Requirements for assessing support behaviour, fastenings and stitching that transfer dead load and catenary forces during fire exposure.
- Calculation methods & measurements: Use of calculation procedures (including EN 1993-1-2 for steel properties at temperature), additional measurements in the reference test, and Annex C rules for extending span length.
- Reporting: Specifies what to include in an extended application analysis and documentation.
Practical applications & users
- Manufacturers of metal sandwich panels seeking to extend test results to a range of product variants without retesting each configuration.
- Fire safety and structural engineers performing fire-resistance assessments and preparing EXAP analyses to obtain EN 13501-2 classifications.
- Test laboratories and certification bodies applying EN 1364-2 results to real‑world ceiling installations.
- Specifiers, architects and building authorities who need to confirm compliance of non‑loadbearing ceiling constructions with fire‑resistance requirements.
- Enables cost‑effective product development, regulatory compliance and risk‑based design decisions for fire safety in buildings.

4 Establishing the field of extended application
4.1 General
An extended application analysis is required when the application differs in one or more parameters from
the one tested and described in the test report and/or in the classification document, and which is not
(fully) covered by the field of direct application of the classification document.
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.
The necessary information for extrapolation of test results shall be assessed during the sampling and
testing as specified in prEN 14509-3:2024, 13.5.1.
4.2 Assumptions in the extended application
The following assumptions are considered when evaluating extended applications for sandwich panels:
a) the ceiling is required to provide fire resistance and shall be classified according to EN 13501-2;
b) the ceiling is assumed to be exposed on one side (either from above or below) to the standardized
heating conditions given in the EN 1363-1 fire resistance test specification or to alternative and
additional procedures given in the EN 1363-2;
c) the supporting construction to which the ceiling is fixed does not significantly deflect during the fire
exposure period;
d) after delamination of the fire exposed facing, the dead load of the panels is carried by a support
structure to which the ends of the sandwich panels are attached; the forces from the dead load will
be distributed to the support structure by the panel fixings from which loadbearing capacity shall be
evaluated;
e) the support structure has at least the same loadbearing capacity, R, of the fire resistance performance
as the sandwich panel ceiling regarding insulation and integrity, if the support structure is on the fire
exposed side in end use condition;
f) the self-weight of the facing and core is calculated from the volume and density of the materials;
g) the calculation of the reduction in the strength properties of steel at elevated temperature shall be in
accordance with EN 1993-1-2.
5 Rules for extended applications of the tested product/construction
5.1 General
When performing extended applications for a tested ceiling, changes can occur either in the materials
and/or in the construction. Both are dealt with in this document. Table 1 and Table 2 list the changes
which may or may not be made in an extended application assessment. The rules for the changes are
either given in Table 1 or Table 2 or in 5.2 and 5.3.

temperature rise near the joint and therefore influence the insulation rating.
5.2 Variations in the materials of the product
5.2.1 General
Metal faced sandwich panels consist of three main materials: facing metal sheets, adhesive and core
material. In the case of auto-adhesively bonded panels, the foamed core material also forms the adhesive
layer during the foaming process.
Changes in the components of a panel can have influences on the fire resistance. The rules in Clause 5
apply to such changes.
5.2.2 Variations in the metal sheets
5.2.2.1 Variations in the coatings
Organic surface coating on fire exposed side has no influence to fire resistance.
Organic surface coating on unexposed side has influence to fire resistance:
— Test results for very light colours are also valid for sandwich panels with light colours and dark
colours (colour definition acc. to EN 14509:2013, Annex E)
— Test results for light metallic colours are also valid for sandwich panels with very light colours, light
colours and dark colours (colour definition acc. to EN 14509:2013, Annex E)
— Test results for light colours are also valid for sandwich panels with dark colours (colour definition
acc. to EN 14509:2013, Annex E)
— Test results achieved with panels with organic coated metal sheet are not valid for panels without
organic coating.
Test results achieved with panels without organic coating are valid for panels with organic coating.
If modifications in the coatings on the unexposed side are made compared to the tested one, the reaction
to fire classification of the product shall be the same or better than the tested one.
5.2.2.2 Variations in the metal material
The following rules are valid for extended applications:
a) when steel is tested the test results are valid for all grades of steel;
b) when stainless steel is tested the test results are valid for all grades of s
