Gypsum elements for suspended ceilings - Definitions, requirements and test methods
This European Standard specifies the characteristics and performance of factory made cast gypsum elements, for which the main intended uses are the construction of suspended ceilings under universal substrates.
It covers the following product performance characteristics: reaction to fire, water vapour permeability, flexural strength (expressed as breaking load) and thermal resistance (expressed as thermal conductivity).
The following performance characteristics are linked to systems assembled with gypsum elements for suspended ceilings: fire resistance, direct airborne sound insulation and acoustic absorption, which can be measured according to the corresponding European test methods. If required, tests should be done on assembled system simulating the end use conditions.
This European Standard describes the reference tests for technical specifications.
This European Standard also covers additional technical characteristics that are of importance for the use and the 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 European Standard.
This European Standard does not cover metal ceiling grids or plasterboard products.
This European Standard excludes stiffening timber roof truss structure applications.

Diese Europäische Norm schließt Anwendungen unter aussteifenden Holzdachbindern aus.
Eléments en plâtre pour plafonds suspendus - Définitions, spécifications et méthodes d'essai
La présente Norme européenne définit les caractéristiques et les performances des éléments en plâtre fabriqués en usine et destinés principalement à réaliser des plafonds suspendus sous des substrats universels.
Elle couvre les caractéristiques de performance suivantes : la réaction au feu, la perméabilité à la vapeur d’eau, la résistance à la flexion (exprimée en terme de charge de rupture) et la résistance thermique (exprimée en terme de conductibilité thermique).
Les caractéristiques de performance suivantes sont liées aux systèmes assemblés à l’aide d’éléments en plâtre pour plafonds suspendus : la résistance au feu, l’isolation acoustique contre les bruits aériens directs et l’absorption acoustique à mesurer conformément aux méthodes d’essai européennes correspondantes. Si nécessaire, il convient de soumettre à essai le système assemblé en simulant les conditions d’utilisation finale.
La présente Norme européenne décrit les essais de référence de ces spécifications techniques.
Elle couvre également les caractéristiques techniques supplémentaires qui sont importantes en vue l’utilisation et de l’acceptation du produit par l’industrie du bâtiment ainsi que les essais de référence de ces caractéristiques.
La présente Norme européenne prévoit l’évaluation de la conformité des produits à la présente norme.
Elle ne couvre pas les ossatures métalliques pour plafonds ni les plaques de plâtre.
En sont également exclues les applications destinées au raidissement des fermes de charpentes en bois.

minimum thickness on the edge: distance between the back and the surface of bearing. 4 Types of gypsum ceiling elements for suspended ceilings 4.1 General Two general kinds of gypsum elements for suspended ceilings are defined: 4.2 Gypsum units 4.2.1 General Rectangular gypsum elements with a flat and smooth face used to make a flat and continuous ceiling. Two types are defined: 4.2.2 Traditional unit Unit with four straight edges. It may be available with bevelled edges (see Figure 1). These units always incorporate integral hangers. NOTE Edges can be square or bevelled.
Figure 2 — Ceiling unit (with rebated edges) 4.3 Gypsum tiles 4.3.1 General Gypsum elements square or rectangular, the surface of which may be plain, patterned or textured. The surface may be perforated to improve sound absorption properties. Perforated tiles may be backed with a protected mineral fibre mat. These tiles are used on metallic grids fixed to the substructure. Following types are defined according with the edges and profiles: 4.3.2 Square edge, type A: exposed grid (see Figure 3).

Volume is calculated from length, width and thickness determined in 6.5. 5.6 Regulated substances Materials used in products shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant document for the material or permitted in the national regulations of the member state of destination. 5.7 Appearance The face of gypsum ceiling elements shall be free from visible surface imperfections such as cavities, stains and efflorescences. 5.8 Dimensions and tolerances Gypsum ceiling elements for suspended ceilings dimensions shall be determined by their length, width and thickness(s) and shall be declared by the producer as nominal dimensions. Tables 2 and 3 give the common dimensions and tolerances for gypsum ceilings units and gypsum tiles according to their type and the edge profiles, when determined in accordance with 6.5. Dimensions of each specimen (as defined in 6.1) shall be within the tolerances given in Tables 2 and 3.

When determined in accordance with 6.8, the mean mass per unit of surface of the gypsum ceilings elements shall not deviate by more than 5 % from the declared value. 5.12 Moisture content The mean moisture content of the gypsum elements for suspended ceilings shall be measured at the time of the departure from the plant. When sampled in accordance with 6.1 and tested in accordance with 6.9, the mean moisture content shall not exceed 6 %, with no individual value exceeding 8 %. 5.13 pH When sampled in accordance with 6.1 and tested in accordance with 6.10 the surface pH of each gypsum element shall be between 6,5 and 10,5.
