European foreword
This document (prEN 16382:2024) has been prepared by Technical Committee CEN/TC 88 “Thermal
insulating materials and products”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16382:2016.
This document includes the following significant technical changes with respect to EN 16382:2016:
— supplementary regulations for the implementation, evaluation and documentation of tests when
using spiral anchors were added.
1 Scope

4 Principle
The pull-through resistance of a plate or spiral anchor through thermal insulation products is determined
by a direct tensile load perpendicular to the surface of the thermal insulation product. The tensile load is
applied by means of a tension plate glued to the test area of the thermal insulation product.
5 Apparatus
5.1 Experimental setup
NOTE In Clause 5, the numbers between brackets refer to the keys of Figure 1 to Figure 3.
The plate or spiral anchor (1) which is to be tested is pulled through the thermal insulation product (3).
The edges of the thermal insulation product are fixed by two square templates with a centric circular
opening (2) and clamps (7). The anchor is positioned in the centre of the sample according to the
manufacturer's instructions. The circular tension plate (5) is glued (6) onto the thermal insulation
product. The anchor is covered previously with a non-adhesive foil. The tension load is introduced to the
thermal insulation product by the circular tension plate which fits into the circular opening of the
template. The anchorage area of the plate anchor is fixed by a suitable device. The tension load is exerted
until failure.
As impacted by EN 206:2013+A2:2021.

5.2 Glue
The glue shall be suitable for the thermal insulation product and for the tension plate (e.g. solvent-free
epoxy or polyurethane based). The glue shall not influence the mechanical properties of the insulation
product.
5.3 Template
The square templates with circular openings shall be rigid. Test results are valid if every distance of the
circular recess to the breaking cone is at least 25 mm.
NOTE Suitable materials for the template are e.g. laminated wood plates of at least 20 mm thickness or steel
plates of at least 7 mm thickness.
The side length b of the templates shall be at least 50 mm larger than the diameter d of the circular recess
s
in the template.
The minimum diameter of the circular recess in the template, d , is calculated from the diameter of the
s
anchor plate dp and the thickness of the tested thermal insulation product, tI, as follows:
d  d + 2t + 50
s p I

where
d is the diameter of the circular recess in the template in mm;
s
d is the diameter of the anchor plate including additional plates if used in mm;
p
t is the thickness of the thermal insulation product in mm.

5.4 Clamping device
At least two clamps (7) at each edge are used to fix the thermal insulation product.
5.5 Tension plate
The circular tension plate (5) introduces the load into the thermal insulation product. The tension plate
shall be rigid. It shall be connected to the testing machine by a self-alignment device in the centre. The
tension plate shall have a diameter of d = d – 10 mm.
z s
NOTE Suitable materials for the tension plate are e.g. laminated wood plates of at least 20 mm thickness or
steel plates of at least 7 mm thickness.
5.6 Tensile testing machine
The tensile testing machine needs to be appropriate for the range of force and the displacement involved
and capable of having a constant crosshead speed adjusted to (20 ± 1) mm/min. It shall be capable of
measuring the force with an error limit of a maximum of 1 % (see EN 1607).
The tensile testing machine shall be capable of continuous recording of load and displacement in order
to report load/displacement graphs for all test specimens.
6 Test specimens
6.1 Thermal insulation product and anchor position
The specimen of the thermal insulation product shall be at least as large as the outer dimensions of the
template described in 5.2.
