EN 14190:2005

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, low 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, flexural strength (breaking load), impact resistance, thermal resistance.The following performance characteristics are linked to systems assembled with producThe 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 document 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 document.
