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.
