This European Standard specifies the characteristics and performance of gypsum fibre boards 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 fibre boards are selected for use according to their type, size, thickness and edge profile. The boards
may 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 may be for floors 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 fibre boards: shear
strength, fire resistance, impact resistance, direct airborne sound insulation, acoustic absorption. If required,
tests have to 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 evaluation of conformity of the product to this EN.
This European Standard does not cover gypsum fibre boards that 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.
