prEN 14509-2:2017 (E)
European foreword
This document (prEN 14509-2:2017) has been prepared by Technical Committee CEN/TC 128 “Roof
covering products for discontinuous laying and products for wall cladding”, the secretariat of which is
held by NBN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a standardisation request given to CEN by the European
Commission and the European Free Trade Association, and supports basic works requirements of EU
Regulation.
For relationship with EU Regulation, see informative Annex ZA, which is an integral part of this
document.
Data obtained from earlier tests in accordance to EN 14509:2006 and 2013 may be used for obtaining
the declared data providing that they do not change significantly.
This European Standard (EN 14509-2) gives the basic rules for use of structural sandwich panels for
structural applications including fixing of panels. The clarification of which application is structural
needs to be given by national provisions. The stabilization parameters needed to contribute to
stabilization of individual structural elements (supporting structure) as defined as structural class II
according to EN 1993-1-3. Sandwich panels fulfilling requirements for applications for structural class
II are seemed to fulfill also applications for structural class III according to EN 1993-1-3.
In EN 14509 (covering panels used as self-supporting) the rules for declaring the basic panel properties
that are common for all applications (use as self-supporting and/or structural) are given.
NOTE 1 In future EN 14509 will become EN 14509-1.
NOTE 2 In future EN 14509-3 will specify sandwich panels used for contribution to overall strength and
stabilization of buildings (structural class I according to EN 1993-1-3) and as axially loaded panels.
prEN 14509-2:2017 (E)
1 Scope
This European Standard specifies requirements for factory made, structural, double skin metal faced
insulating sandwich panels, which are intended for discontinuous laying in the following applications:
a) roofs and roof cladding (e.g. for refurbishment);
b) external walls and wall cladding (e.g. on brick walls for refurbishment or sandwich panels on liner
trays);
c) walls (including partitions) and ceilings within the building envelope.
It is essential that structural double skin metal faced insulating sandwich panels according to this
European Standard (EN 14509-2) fulfil the requirements of EN 14509.
This European Standard (EN 14509-2) gives the basic rule for use of structural sandwich panels for
structural applications including fixing of panels. The clarification of which application is structural
needs to be given by national provisions. The stabilization parameters needed to contribute to
stabilization of individual structural elements (supporting structure) as defined as structural class II
according to EN 1993-1-3 are included.
The insulating core materials covered by this European Standard are rigid polyurethane, expanded
polystyrene, extruded polystyrene foam, phenolic foam, cellular glass and mineral wool.
NOTE Polyurethane (PUR) includes polyisocyanurate (PIR).
Due to durability performance reason coated face material of steel is used only (both organic and
metallic coating). Uncoated steel is not used as face material.
Panels with edge details that utilise different materials from the main insulating core are included in
this European Standard if there is no influence on mechanical performance of the panel.
Panels used in cold store applications are included in this European Standard. Panels, put on the market
as a component of a cold storage room, building and/or building envelope kit are covered by ETA-
Guideline 021 “Cold storage premises kits”.
When manufactured in accordance with this European Standard and if satisfying the type testing and
FPC criteria the panels can be considered as impermeable to water. The water permeability of the
assembly is a function of its installation and is only relevant to the joints and fixings.
This European Standard does not cover the following:
d) sandwich panels with a declared thermal conductivity for the insulating core greater than defined
in the relevant harmonized European Standards for insulation materials;
e) products consisting of two or more clearly defined layers of different insulating core materials
(multi-layered);
f) curved panels;
g) perforated panels;
h) hidden fixings under permanent tension load, e.g. for ceilings;
i) special type of fasteners such as ‘T’ support for ceiling, threaded rods with clamps for wall, omega
and clamps for wall and ceiling, injected joint with flashing and threaded rods for wall and ceiling.

5.5.4 Material safety factors (γ )
M
The material safety factors for bending moment capacity (or wrinkling stress), shear strength,
compression strength and fastening shall be determined in accordance with EN 14509.
The material safety factors of fixings shall be determined according to Annex E.
The standard deviation may be calculated on basis of the increasing amount of data resulting from FPC
and can become a part of the manufacturer’s documentation.
The material safety factors are based on Type Testing (see EN 14509:2013, A.16.3) but can be
determined also to correspond to the level achieved in FPC follow-up.
