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. NOTE1 For editorial reasons in this document the term \'window\' is used for window/door. NOTE2 Profiles made from PVC-U materials with reinforcements (e.g. glass fibres) are not part of this scope.
