1 Scope
This European Standard specifies the classifications, requirements and test methods for non-coated
unplasticized poly(vinyl chloride) (PVC-U) profiles with light coloured surfaces intended to be used for
the fabrication of windows and doors.
It is applicable to PVC-U profiles with the colorimetric co-ordinates measured on the visible surfaces, as
follows:
— L* ≥ 82 (chromaticity co-ordinate Y ≥ 60),
— –2,5 ≤ a* ≤ 5,
— –5 ≤ b* ≤ 15.
NOTE 1 For editorial reasons in this document the term "window" is used for window/door.
NOTE 2 Profiles made from PVC-U materials with reinforcements (e.g. glass fibres) are not part of this scope.

4.1 General
In EN 12608-1 various aspects of performance are classified. The selection of appropriate classes
necessary to fulfil national requirements may be given in a national foreword of EN 12608-1.
4.2 Classification of climatic zones
For the purposes of this document, geographical Europe is divided in two climatic zones M (moderate
climate) and S (severe climate) as defined in Table 1. These climatic zones do not cover climates outside
of geographical Europe.

Class Moderate climate M Severe climate S

surface
and or
a
Average temperature of the warmest month per year < 22 °C ≥ 22 °C

Values measured according the specifications of the World Meteorological Organisation (WMO).

!NOTE For the purpose of this document, “moderate climate” refers in general to warm and humid weathering
conditions and “severe climate” to hot and dry weathering conditions. The relevant moderate and severe test
methods for artificial weathering can be found in EN 513."
Profiles which are designed to be used in a severe climate (S) may also be used in a moderate climate
(M).
In those countries where the two climatic zones exists, care should be taken that profiles designed for a
moderate climate (M) are not used in the severe climate (S).
4.3 Classification of main profiles according to the resistance to impact by falling mass
For the resistance to impact by falling mass at –10 °C, the main profiles shall be classified according to
Table 2.
Table 2 — Classification of main profiles according to the resistance to impact by falling mass
Class 0 I II
Falling mass (g) NPD 1 000 1 000
Falling height (mm) NPD 1 000 1 500
NPD: No Performance Determined.
NOTE This property is assessed to ensure the extrusion process is carried out correctly.
It is recommended that class 0 is applied only when the profile geometry dictates that this test cannot
be performed.
4.4 Classification of main profiles according to the wall thickness of the external walls
!For the wall thickness of the external walls, the main profiles shall be classified according to Figure 2
and Table 3.
Figure 2 shows the areas of typical profiles where the wall thicknesses of external walls shall satisfy the
requirements given in Table 3."
