1 Scope
This document establishes a system of designation for profiles made of unplasticized poly(vinyl chloride)
(PVC-U) intended to be used for building applications. This system is intended to be used in product
specification after the application is specified.
NOTE It is intended to use this system for the designation of PVC-U profiles for information related to technical
literature of the manufacturer, not for the marking of the products.
This part is applicable to PVC-U profiles of any colour, obtained by a mono-extrusion or a co-extrusion
process, with or without surface finishing (e.g. foil, paint or print).
This document defines minimum requirements for the surface finishing of PVC-U profiles.
Profiles for the management of electrical power cables, communication cables and power track systems
used for the distribution of electrical power, profiles for windows or doors and profiles for guttering are
not covered by this document .

5.6.1 General
To test durability, the profile is subjected to either natural or artificial ageing. Assessment of the
durability is based on the following criteria:

b) the tensile-impact strength of the PVC-U profiles after ageing;
c) the visual inspection of the PVC-U profiles after ageing;
d) the adhesion of the surface finishing of the PVC-U profiles after ageing (for Type 3, Type 4 and Type 5
profiles, only).
5.6.2 Test methods for ageing
5.6.2.1 Outside building applications
Ageing shall be carried out according to either an artificial ageing test method or a natural ageing test
method.
