(Main)Specification for masonry units - Part 4: Autoclaved aerated concrete masonry units
Specification for masonry units - Part 4: Autoclaved aerated concrete masonry units
This EN specifies the characteristics and performance requirements of autoclaved aerated concrete (AAC) masonry units for which the main intended uses are different types of loadbearing and non-loadbearing applications in all forms of walling including single leaf, cavity, partitions, retaining, basement and general use below ground level, including walling for fire protection, thermal insulation, sound insulation and chimneys.
Festlegungen für Mauersteine - Teil 4: Porenbetonsteine
Diese Europäische Norm beschreibt die Eigenschaften und Leistungsanforderungen für dampfgehärtete Porenbetonsteine, die vorwiegend in tragendem oder nichttragendem Mauerwerk in Bauwerken des Hoch- oder Tiefbaus verwendet werden. Die hierin beschriebenen Mauersteine eignen sich für alle Arten von Mauerwerk einschließlich einschaligen Mauerwerks, zweischaligen Mauerwerks, Trennwänden, Stützmauern und Fundamenten sowie für die allgemeine Verwendung unter der Erdoberfläche. Sie dienen dem Brand-, Wärme- und Schallschutz. Sie werden auch zur Herstellung von Schornsteinmauerwerk (ausgenommen bei der Auskleidung von Rauchabzügen) verwendet.
Diese Norm beschreibt die Anforderungen, z.B. an Festigkeit, Rohdichte und Maßgenauigkeit. Ferner werden die Konformitätsbewertung und die Kennzeichnung der von dieser Europäischen Norm erfassten Produkte festgelegt.
Diese Europäische Norm gilt nicht für geschosshohe Tafeln, Steine für die Auskleidung von Rauchabzügen oder für Steine zur Herstellung von feuchtesperrenden Schichten. Sie gilt nicht für Steine mit einem Wärmedämmstoff, der auf die Seiten des Steins, die Feuer ausgesetzt sein können, aufgebracht ist. Sie gibt weder genormte Größen für Porenbetonsteine noch Sollmaße und Winkel für Form- und Ergänzungssteine an. Sie enthält keine Grenzabmaße für Form- und Ergänzungssteine. Produkte zur Herstellung von feuchtesperrenden Schichten oder zur Auskleidung von Schornsteinen werden nicht behandelt.
Spécifications pour éléments de maçonnerie - Partie 4: Eléments de maçonnerie en béton cellulaire autoclavé
Cette Norme européenne spécifie les caractéristiques et les exigences de performances des blocs de maçonnerie en béton cellulaire autoclavé (BCA) dont les principales utilisations prévues sont différents types d'applications porteuses et non porteuses sous toutes les formes de murs, y compris les murs à simple ou double paroi, les cloisons, les murs de soutènement, les soubassements et les murs utilisés en sous-sol. Ils peuvent constituer une protection contre l'incendie, une isolation thermique et acoustique et un chemisage pour les conduits de fumée (excepté pour les conduits intérieurs de fumée).
Elle définit d'une part les performances relatives par exemple à la résistance, la masse volumique et les tolérances dimensionnelles et permet d'autre part d'évaluer la conformité du produit par rapport à cette Norme Européenne.
Elle inclut également les exigences de marquage des produits qui y sont traités.
Cette Norme européenne ne couvre pas les exigences concernant les panneaux hauteur d'étage, les conduits intérieurs de fumée ni les blocs comportant un isolant thermique rapporté sur les faces susceptibles d'être exposées au feu. Elle ne spécifie pas les formats normalisés des blocs en béton cellulaire autoclavé, les dimensions de fabrication courante, ni les caractéristiques angulaires des blocs de forme particulière et des blocs accessoires. Elle ne donne pas les tolérances dimensionnelles pour les blocs de forme particulière et les blocs accessoires. Elle ne couvre pas les produits destinés à servir d'assise anti-humidité ou de conduits intérieurs de fumée.

1 Scope
This European Standard specifies the characteristics and performance requirements of autoclaved
aerated concrete (AAC) masonry units for which the main intended uses are different types of load
bearing and non-load bearing applications in all forms of walling including single leaf, cavity,
partitions, retaining, basement and general use below ground level, including walling for fire
protection, thermal insulation, sound insulation and the fabric of chimneys (excluding chimney flue
units).
It defines the performance related to e.g. strength, density, dimensional accuracy etc. and provides
for the evaluation of conformity of the product to this European Standard.
The marking requirement for products covered by this European Standard is included.
This European Standard does not cover the requirements for storey height panels, flue linings and
masonry units with an incorporated thermal insulation material bonded to the faces of the unit
susceptible to be exposed to fire. It does not specify standard sizes for autoclaved aerated concrete
units nor standard work dimensions and angles of specially shaped and accessory units. It does not
give permissible deviations for specially shaped and accessory units. It does not cover products
intended for use as a damp proof course or the lining of a chimney.
