DIN EN 520:2009-12 EN 520:2004+A1:2009 (E) 4 Introduction Gypsum plasterboards are composed of a plaster core encased in, and firmly bonded to paper liners to form flat rectangular boards. !This composition allows them properties which make gypsum plasterb
25、oards particularly suitable for use in situations where fire protection, sound and thermal insulation are required.“ Gypsum plasterboards may be fixed by various methods e.g. nailing, screwing or sticking with gypsum based or other adhesives. They may also be inserted in a suspended ceiling system.
26、Gypsum plasterboards 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 floor
27、ing and sheathing application. Diagrams 1 and 2 show the relationship between this standard and the package of standards prepared to support the families of gypsum and ancillary products.

29、ng operations. It includes boards designed to receive either direct surface decoration or gypsum plaster. This document covers the following product performance characteristics: reaction to fire, water vapour permeability, flexural strength (breaking load), impact resistance and thermal resistance.
30、The following performance characteristics are linked to systems assembled with plasterboards: shear strength, fire resistance, impact resistance !,“ direct airborne sound insulation and acoustic absorption to be measured according to the corresponding European test methods. If required, tests should
31、 be done on assembled systems simulating the end use conditions. This document covers also 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 evaluat
32、ion of conformity of the product to this document. This document does not cover plasterboards, which have been subject to any secondary manufacturing operations (e.g. insulating composite panels, plasterboards with thin lamination, etc.). 2 Normative references The following referenced documents are
