Overview

prEN 12608-2 (CEN) defines the classification, requirements and test methods for laminated unplasticized polyvinyl chloride (PVC‑U) profiles intended for the fabrication of windows and doors. Part 2 of the EN 12608 series covers PVC‑U profiles that are covered with decorative or protective foils bonded with adhesives for external use. The document sets out how to assess materials, foils and adhesive systems and specifies relevant test methods for durability and performance.

Key topics and technical requirements

• Scope and terminology
  • Defines key terms such as base profile, laminated profile, foil and adhesive system used across lamination processes.
• Classification
  • Classification of main base profiles by external wall thickness and impact resistance.
  • Classification of base profile materials and foils according to resistance to artificial weathering (UV resistance classes).
• Requirements for base profiles
  • Material and appearance requirements, dimensional tolerances, heat reversion and impact resistance considerations (aligned with EN 12608‑1 where applicable).
• Requirements for foils
  • Appearance, resistance to artificial weathering, solar direct reflectance and, where applicable, cross‑cut resistance for lacquered foils.
• Requirements for adhesive systems
  • Adhesion of foils before and after artificial ageing; guidance for primer/glue systems and peel strength assessment.
• Requirements for laminated profiles
  • Visual appearance, straightness, behaviour after heat storage, peel strength, and strength of welded corners and T‑joints.
• Test methods
  • Visual inspection, peel strength determination after artificial ageing, spectral analysis for reflection behaviour (Annex C), and other referenced test standards (e.g., EN ISO 4892‑2 xenon‑arc weathering, EN 17271 peel testing).

Applications and who uses it

This standard is practical for:

• PVC‑U profile manufacturers establishing product specifications for laminated profiles.
• Window and door fabricators selecting durable laminated profiles for external installations.
• Quality control and testing laboratories performing peel, weathering and adhesion tests.
• Specifiers, architects and procurement teams requiring compliance evidence in tenders and technical dossiers.
• Regulators and certification bodies assessing conformity to European practice for laminated PVC‑U fenestration products.

By following prEN 12608‑2, stakeholders can specify, test and validate laminated PVC‑U profiles for outdoor use-helping ensure durability, weather resistance and reliable adhesion of decorative/protective foils.

Related standards

• EN 12608‑1 (Non‑coated PVC‑U profiles)
• EN 17271 (Peel strength of laminated profiles)
• EN ISO 4892‑2 (Xenon‑arc artificial weathering)
• Other referenced EN/ISO methods for impact, heat reversion, colourimetry and joint strength

4 Classifications
4.1 General
This document establishes the following classifications:
a) Classification of main base profiles according to the wall thickness of the external walls (see 4.2);
b) Classification of main base profiles according to resistance to impact by falling mass (see 4.3);
c) Classification of base profile materials according to the resistance to artificial weathering (see 4.4);
d) Classification of foils according to the resistance to artificial weathering (see 4.5).
The selection of appropriate classes necessary to fulfil national requirements may be given in the
national foreword of this document.
4.2 Classification of main base profiles according to the wall thickness of the external
walls
For the wall thickness of the external walls, the main base profiles shall be classified according to
EN 12608-1:2016+A1:2020, 4.4 (Figure 2 and Table 3).
4.3 Classification of main base profiles according to the resistance to impact by falling
mass
For the resistance to impact by falling mass, the main base profiles shall be classified according to
EN 12608-1:2016+A1:2020, 4.3.
4.4 Classification of base profile materials according to the resistance to artificial
weathering
Resistance to artificial weathering of base profile materials shall be determined according to Annex A.
There are two possibilities for the classification of base profile materials which are used for the profile’s
surface according to the resistance to artificial weathering:
a) for UV resistant materials (UVM) classification according to climatic zones conforming to
EN 12608-1:2016+A1:2020, 4.2, applies (classes M and S);
b) for reduced-UV resistant materials the class “RUVM” applies.
4.5 Classification of foils according to the resistance to artificial weathering
The resistance to artificial weathering of foils shall be classified according to Table 1 after testing
according to 6.3.
For guidance regarding the selection of the appropriate foil class, see Annex B.

5 Requirements for base profiles
5.1 Base profiles in conformance with EN 12608-1
If the base profile is in accordance with EN 12608-1, no further requirements for the base profile apply.
5.2 Other base profiles
5.2.1 Materials
All requirements for materials of other base profiles than described in 5.1 are given in Annex A. To fulfil
requirements according to Annex A materials of type rPVC may be re-stabilized and/or enhanced with
additives (e.g. modifiers, pigments, lubricants) before use.
PVC based materials are defined according to EN 17508.
The use of these materials on surfaces of profiles is given in Table 2 and Figure 1.
It is permitted to use a reduced-UV resistant virgin material (RUVM) on the surface when the sight
surfaces of the profiles are covered with foil (see Table 2).
If PVC-U recyclate (rPVC) or non-UV resistant virgin material (NUVM) is used for the base profile the
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
0,2 mm;
d) there is no requirement for minimum thickness of the coextruded surface layer at the inside surface
of grooves with an entry width ≤ 5 mm (see Figure 1).

surface defects when viewed in accordance with 9.1. The appearance of the surface of the foiled profile
shall not be adversely affected by the base profile.
The edges of the base profiles shall be clean and burr-free.
5.2.3 Dimensions and tolerances of main base profiles
Requirements concerning dimensions and tolerances of the main base profile shall be the same as for
main base profiles according to 5.1.
