This European Standard specifies the characteristics and performance of products which have been produced by reprocessing gypsum boards manufactured according to EN 520, EN 15283-1 and EN 15283-2. Reprocessing may include cutting, perforating, edge profiling, decorating and laminating membranes of other materials for functional or decorative purposes, attaching fixings including supports e. g. for partitions. Examples of reprocessing operations are given in Annex B. The products are intended for use in wall, ceiling and floor applications, where they may be fixed directly to the background, or they are used in systems assembled in conjunction with the structure to form separate or suspended linings. The products can be customized to fit the intended application offering a wide range of aesthetic, functional and decorative solutions of modular or non-modular design. This standard does not cover gypsum board thermal/acoustic insulation composite panels according to EN 13950 and prefabricated gypsum plasterboard panels with a cellular paperboard core according to EN 13915.
