This European Standard specifies the characteristics and performance of products which have been produced
from gypsum plasterboards manufactured according to EN 520 by reprocessing. 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. A fuller list of reprocessing
operations is given in Annex B.
Gypsum plasterboards subject to reprocessing operations may be suitable for extended applications such as
suspended ceilings providing sound absorption, flooring, self decorative finishes, Iow emissivity characteristics,
moisture vapour control and X-ray protection.
The products are intended for use in wall, ceiling and floor applications, where they may be fixed direct to the
background, or they are used in systems assembled in conjunction with the structure to form separate or
suspended linings. The products offer a wide range of aesthetic solutions of modular or non-modular design.
This standard covers the following product performance characteristics: reaction to fire, water vapour
permeability, stability in case of ceiling elements, fiexural strength (breaking load), impact resistance, thermal
resistance.
The following performance characteristics are linked to systems assembled with products from reprocessing:
shear strength, direct airborne sound insulation and acoustic absorption to be measured according to the
corresponding European test methods. If required, tests should be done on assembled systems simulating the
end use conditions.
This European standard also covers additional technical characteristics that are of importance for the use and
acceptance of the product by the construction industry and the reference tests for these characteristics.
It provides for the evaluation of conformity of the product to this standard.
This standard does not cover gypsum plasterboard thermal/acoustic insulation composite panels and
prefabricated gypsum wallboard panels according to prEN 13950 and prEN 13915, respectively.
