This British Standard specifies requirements for PVC-U extruded hollow profiles for windows and doorsets in which any surface to be exposed externally is covered by means of an adhesive layer (foil) prior to fabrication. It applies to both the completed product, and the base profile prior to covering.

It applies up to the point of fabrication into windows or doorsets, provided the profiles have been stored in accordance with the system supplier’s recommendations.

It does not apply to white profiles without a surface covering layer; these are specified in BS EN 12608.
