following shall apply:
a) these materials may be used for the core of a profile, where any visible surfaces are completely
covered by coextrusion with a virgin material (UVM), an UV resistant internally reused material
(IRM) or a reduced-UV resistant virgin material (RUVM); the thickness of the coextruded layer is
determined according to EN 12608-1:2016+A1:2020, 6.4;
b) for sight surfaces, the minimum value of thickness of the coextruded surface layer shall be 0,5 mm;
c) for non-sight visible surfaces, the minimum thickness of the coextruded surface layer shall be

oSIST prEN 12608-2:2022
prEN 12608-2:2022 (E)
After the exposure, the foil shall satisfy the following requirements:
a) when evaluated by a visual assessment using the grey scale as specified in EN 20105-A02, the
colour fastness between the unexposed and exposed specimens shall be ≥ 3;
b) when evaluated by a visual assessment using a magnifying factor 20 × the surface of the foil shall

c) for lacquered foils only: Class 0 shall be reached in the cross cut test according to EN ISO 2409.
6.4 Solar direct reflectance
Solar direct reflectance shall be tested in accordance with Annex C and calculated according to EN 410.
NOTE Based on the present state of knowledge (without specific justification) the value is usually higher than
20 %. Applications using foils with values below 20 % can be investigated according to the recommendations of
the profile supplier.
6.5 Resistance to cross cut (only for lacquered foils)
Class 0 shall be reached in the cross cut test according to EN ISO 2409.
7 Requirements for adhesive systems
7.1 General
The adhesive system shall be defined and appropriate to laminate PVC-U window profiles with foils and
it shall fulfil the requirements of 7.2 and 7.3. This ensures the fitness for use of the adhesive system
depending on the type of foil used.
For testing purposes primers are grouped as follows:
a) primers based on methylene chloride, acetone and MEK (methyl ethyl ketone);
b) low-VOC (volatile organic compounds) primers.
The test result of an adhesive system is valid for:
— the type of foil used for testing; one type is defined as all foils with the same formulation of the base
layer and the same construction described by materials, thickness of each layer of the stack and
underside coating (e.g. primer) of the foil regardless of the colour;
— if a primer is part of the adhesive system: the group of primers it belongs to as listed above; a
primer that cannot be assigned to either of the above two groups shall be tested individually with
each adhesive and each foiling type.
7.2 Adhesion of the foil
When tested in accordance with EN 17271 the value for the peel strength shall be ≥ 2,5 N/mm.
7.3 Adhesion of the foil after artificial ageing
The peel strength determined after storage of a laminated profile in a hot and humid climate according
to 9.2 shall be ≥ 1,5 N/mm.

8 Requirements for laminated profiles
8.1 General
On plane visible surfaces, compliance with the parameters specified by the foil and adhesive
manufacturers, such as the quantity of adhesive and the primer applied, shall be ensured.
8.2 Appearance
When viewed in accordance with 9.1, there shall be no significant difference between the corresponding
reference sample of the foil and the laminated profile.
Surfaces that are permanently invisible when the window is installed are excluded from this
requirement.
8.3 Deviation from straightness of the laminated main profiles
When measured in accordance with EN 12608-1:2016+A1:2020, 6.2, the deviation from the
straightness of the laminated main profile shall be ≤ 1 mm for a length of 1 m.
8.4 Behaviour after heat storage
8.4.1 General
Testing for behaviour after heat storage according to EN 478 is performed to assess both the extrusion
of the base profile and the lamination process.
The material properties and extrusion process are tested by heating up to 150 °C. The behaviour of the
base profile is in the focus of this examination. Due to substances included in the PVC-U matrix which
evaporate at this temperature a blistering between base profile and foil is possible. This phenomenon is
not evaluated as a failure.
If such defects occur at 150 °C it is assumed that they are not caused by an incorrect lamination process.
This can be differentiated by heating up to 120 °C, a temperature which defines a threshold for the
characteristics of adhesive and foil only.
Therefore, if the
