Admixtures and fill
27、ers may also be present. They are usually continuously produced on an industrial scale. The properties of gypsum fibre boards make them particularly suitable for use in situations where there are requirements for fire protection, sound, thermal insulation or shear strength. Gypsum fibre boards may b
28、e fixed by various methods e.g. nailing, screwing, stapling or sticking with gypsum based or other adhesives. They may also be inserted in a suspended ceiling system or laid in floor constructions. Gypsum fibre boards may be finished with direct surface decoration or gypsum plaster. They may be furt
29、her processed into a range of other products. BS EN 15283-2:2008+A1:2009EN 15283-2:2008+A1:2009 (E) 8 1 Scope 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 manufact
30、uring 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 s
31、uspended 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 resi
32、stance. 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 metho
33、ds 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 produ
34、ct 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. 2 Normative references The following re
