European foreword
This document (prEN 14509-4:2021) 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.
Introduction
The principles for determination of declared values of the characteristics to be expressed are given in
prEN 14509-1 for self-supporting applications and in FprEN 14509-2 for structural applications.
1 Scope
This document specifies test methods for determination of characteristics for fixing of factory-made
double skin metal faced insulating sandwich panels (hereafter referred to as sandwich panels) to
substructure and for stabilization of substructure. Sandwich panels are used in elements for both self-
supporting and structural applications in roofs, in external and internal walls (including partitions) and
in ceilings in buildings as well as those in cold store applications.
NOTE The description of self-supporting sandwich panels is given in prEN 14509-1 and for structural
sandwich panels in FprEN 14509-2.

3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1.1
bond, bonding
adhesion between the face(s) and the core normally provided by an adhesive
3.1.2
ceiling
covering over an internal area
3.1.3
core
layer of material, having thermal insulating properties, which is bonded between two metal faces,
thickness of metal face minus thickness of metal and organic coating

As impacted by EN 1993-1-3:2006/AC:2009.
Note 1 to entry: Panels with special edge details in the longitudinal joints may utilize different core materials from
the main insulating core (e.g. for improved fire performance) if these edge details do not influence on mechanical
performance of the panel.
3.1.4
edge, longitudinal edge
side of the panel where adjacent panels join together in the same plane
3.1.5
face, facing
flat, lightly profiled or profiled thin metal sheet firmly bonded to the core
3.1.6
joint
interface between two panels where the meeting edges have been designed to allow the panels to join
together in the same plane
Note 1 to entry: The joint may incorporate interlocking parts that enhance the mechanical properties of the
system as well as improving the thermal, acoustic and fire performance and restricting air movement.
Note 2 to entry: The term 'joint' does not refer to a junction between cut panels or a junction where the panels are
not installed in the same plane.

4 Testing of the resistance of fixings of sandwich panels to supporting
structures
4.1 General
4.1.1 Type of fixings and panel families
This document covers the resistance of fixing of panels to supporting structures and the failure modes
in the sandwich panel. It does not cover the failure of the fastener itself or failure of the fixing in the
supporting structure. Thus, the failure mode for tension is generally a pull-through failure of the visible
fixing and the failure mode of the hidden fixing a failure of the joint or of the load spreading plate (if
applicable). A pull-through failure is used as a common name for these failure modes. In addition, the
shear failure mode of fixing is covered by this document.
The types of fixing of panels to supporting structure covered by this document are:
— visible fixings;
— hidden fixings.
NOTE 1 Combinations of these fixing types are also possible.
For the fixing of panels to supporting structure, failure modes in suppo
