scope:

This European Standard establishes a system of designation for profiles made of unplasticized poly(vinyl chloride) (PVC-U) intended to be used for building applications. This part is applicable to light coloured and coloured PVC-U profiles, obtained by a mono-extrusion or a coextrusion process, with or without a laminated foil or with a lacquered-coating. It specifies test methods and test parameters. This method of designation is intended to be used in product specification when the application is specified.
