Gypsum blocks - Definitions, requirements and test methods
This European Standard specifies the characteristics and performance of gypsum blocks with smooth faces for which the main intended uses are construction of non-load bearing partitions or independent wall linings and the fire protection of columns, lift shafts, etc. The gypsum blocks are not used to build ceilings.
It covers the following performance characteristics related to the essential requirements:
reaction to fire;
resistance to fire;
direct airborne sound insulation;
release of dangerous substances;
to be measured according to the corresponding European test methods, as well as:
thermal resistance,
to be calculated from the thermal conductivity values given in 4.3.2.
It describes the reference tests for technical specifications.
This European Standard also covers additional technical characteristics that are of importance for the use and acceptance of the product by the construction industry:
convenience class for density;
convenience class for pH;
surface hardness.
It provides for the evaluation of conformity of the product to this European Standard.
This European Standard does not cover gypsum blocks of thickness less than 50 mm or gypsum storey height units.
Gips-Wandbauplatten - Begriffe, Anforderungen und Prüfverfahren
Diese Europäische Norm legt Eigenschaften und Leistungsmerkmale von Gips-Wandbauplatten mit glatten Sichtflächen, die hauptsächlich zur Herstellung nicht tragender Trennwände, freistehender Wand-Vorsatzschalen sowie Brandschutzbekleidungen von Stützen, Schächten usw. eingesetzt werden, fest. Gips-Wandbauplatten werden nicht zur Herstellung von Decken verwendet.
Diese Europäische Norm enthält Aussagen zu den folgenden, auf den wesentlichen Anforderungen beruhenden Leistungsmerkmalen:
Brandverhalten;
Feuerwiderstand;
Luftschalldämmung;
Freisetzung gefährlicher Stoffe,
die durch die entsprechenden europäischen Prüfverfahren nachzuweisen sind, sowie zum
Wärmedurchlasswiderstand,
der aus den in 4.3.2 angegebenen Werten für die Wärmeleitfähigkeit zu berechnen ist.
In dieser Norm werden die Referenzprüfverfahren für technische Festlegungen definiert.
Diese Europäische Norm behandelt darüber hinaus zusätzliche technische Eigenschaften, die für die Akzeptanz und die Anwendung der Platten durch die Bauwirtschaft wichtig sind:
Rohdichteklasse;
pH-Wert-Klasse;
Oberflächenhärte.
Sie regelt die Bewertung der Konformität von Produkten nach dieser Europäischen Norm.
Diese Europäische Norm gilt nicht für Gips-Wandbauplatten mit Dicken unter 50 mm oder für geschosshohe Plattenelemente.
Carreaux de plâtre - Définitions, spécifications et méthodes d'essai
La présente Norme européenne spécifie les caractéristiques et les performances des carreaux de plâtre à
faces lisses destinés principalement à la construction de cloisons de distribution non porteuses ou de
doublages indépendants et à la protection contre l’incendie de poteaux, de cages d’ascenseurs, etc. Les
carreaux de plâtre ne sont pas utilisés pour réaliser des plafonds.
Elle couvre les caractéristiques de performance suivantes en relation avec les exigences essentielles :
⎯ la réaction au feu ;
⎯ la résistance au feu ;
⎯ l'isolation contre les bruits aériens directs ;
⎯ l’émission de substances dangereuses ;
à mesurer selon les méthodes d’essai européennes correspondantes, ainsi que :
⎯ la résistance thermique,
à calculer à l’aide des valeurs de conductivité thermique données en 4.3.2.
Elle définit les essais de référence pour les spécifications techniques.
La présente Norme européenne couvre également les caractéristiques techniques suivantes qui sont
importantes pour l’emploi et la réception du produit par l’industrie du bâtiment :
- classes de convenance pour la densité ;
- classes de convenance pour le pH ;
- dureté superficielle.
Elle prévoit l’évaluation de la conformité du produit à la présente Norme européenne.
La présente Norme européenne ne couvre pas les carreaux de plâtre d’épaisseur inférieure à 50 mm, ni les
éléments en plâtre de hauteur d’étage.

NOTE 1 The gypsum block is a rectangular parallel piped, with tongues and grooves on at least two of their opposite edges. NOTE 2 It may be coloured by pigmentation 3.1.2 solid gypsum block gypsum block manufactured without cavities 3.1.3 cavity gypsum block gypsum block which incorporates preformed cavities 3.1.4 preformed cavity formed cavity parallel to the faces which may or may not pass completely through the block. It may run parallel with the height or the length (see Figure 1) 3.1.5 face plain and smooth surface intended to provide the finish of a partition (see Figure 1) 3.1.6 edge extreme side of the gypsum block having tongues and grooves (see Figure 1) 3.1.7 thickness distance between the two faces of a gypsum block (see Figure 1)
Key 1 Preformed cavities 2 Face 3 Thickness 4 Height 5 Length Figure 1 — Gypsum block 3.2 Symbols For the purposes of this European Standard, the following symbols apply. ρ gross dry density, in kilograms per cubic metre (kg/m3); λ thermal conductivity, in Watts per metre per Kelvin (W/m·K); λ 23-50 thermal conductivity of the hardened plaster when in equilibrium at 23 °C and 50 % relative humidity, in Watts per metre per Kelvin (W/m·K); M mass of the gypsum block in kilograms (kg). 4 Requirements 4.1 Fire behaviour 4.1.1 Reaction to fire Gypsum blocks are classified in Euroclass A.1 (no contribution to fire) without testing when they contain less than 1 % by weight or volume (whichever is the more onerous) of organic material. If they contain 1 % or more, by weight or volume of organic material, they shall be determined and classified in accordance with EN 13501-1.
class H 3 (water absorption class).
Table 3 – Density class Colour Density class Pink a High density Natural Medium density Yellow a Low density a The visual identification by colour of the density class is only applied on class H 3 (water absorption class).
4.4.2 Gypsum blocks are manufactured in three types of density (see 4.8). Some blocks can be hydrophobic (see 4.13). 4.5 Release of dangerous substances NOTE For CE marking purposes, see Annex ZA.1 NOTE 1 and NOTE 2. 4.6 Dimensions and tolerances 4.6.1 Dimensions Gypsum block dimensions are determined by the thickness, the length and the height. The thickness shall be at least 50 mm and shall not exceed 150 mm. The length shall not exceed 1 000 mm. The height shall be determined in conjunction with the length so that the surface area of a block is at least 0,20 m2. NOTE Preferred dimensions are for thickness : 50 mm, 60 mm, 70 mm, 80 mm, 100 mm, for length : 666 mm and for height : 500 mm.
