This European Standard specifies the characteristics and performance of gypsum boards with mat reinforcement intended to be used in building construction works including those intended for secondary manufacturing operations. It includes boards designed to receive either direct surface decoration or gypsum plaster.Gypsum boards with mat reinforcement are selected for use according to their type, size, thickness and edge profile. The boards can be used for example to provide dry lining finishes to walls, to fixed and suspended ceilings, to partitions, or as cladding to structural columns and beams. Other uses can be for floors, ventilation and smoke extraction ducts, cable trays and sheathing applications.This European Standard covers the following product performance characteristics: reaction to fire, water vapour permeability, flexural strength, and thermal resistance.The following performance characteristics are linked to systems assembled with gypsum boards with mat reinforcement: shear strength, fire resistance, impact resistance, direct airborne sound insulation, acoustic absorption. If required, tests should be done according to the corresponding European test methods 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 and the reference tests for these characteristics. It provides for the evaluation of conformity of the product to this EN.This European Standard does not cover gypsum boards with mat reinforcement which have been subject to any secondary manufacturing operations (e.g. insulating composite panels, boards with thin lamination etc.).Products covered by EN 520 or EN 13815 are excluded.
