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.

sandwich panels in FprEN 14509-2.

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
