(Main)Specification for masonry units - Part 4: Autoclaved aerated concrete masonry units
Specification for masonry units - Part 4: Autoclaved aerated concrete masonry units
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.
Festlegungen für Mauersteine - Teil 4: Porenbetonsteine
Diese Europäische Norm legt die Eigenschaften und Leistungsanforderungen für dampfgehärtete Poren-beton¬steine fest, die vorwiegend in tragendem oder nichttragendem Mauerwerk in Bauwerken des Hoch- oder Tief¬baus verwendet werden und für alle Arten von Mauer¬werk einschließlich einschaligen Mauerwerks, zweischaligen Mauerwerks, Trennwänden, Stützmauern und Fundamenten sowie für die allgemeine Verwendung unter der Erdoberfläche geeignet sind, einschließlich Brand-, Wärme- und Schallschutz. Sie werden auch zur Herstellung von Schornsteinmauerwerk (ausgenommen bei der Aus¬kleidung von Rauch-abzügen) verwendet.
Sie legt die Anforderungen, z. B. an Festigkeit, Rohdichte und Maßgenauigkeit usw., und die die Konformitäts¬bewertung des von dieser Europäischen Norm erfassten Produktes fest.
Die Kennzeichnung der von dieser Europäischen Norm erfassten Produkte ist 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 Wärme-dämm¬stoff, 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 feuchte¬sperrenden Schichten oder zur Auskleidung von Schornsteinen werden nicht behandelt.
Spécifications pour éléments de maçonnerie - Partie 4: Éléments de maçonnerie en béton cellulaire autoclavé
La présente Norme européenne spécifie les caractéristiques et les exigences de performances des éléments 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 éléments de maçonnerie comportant un isolant thermique rapporté sur les faces susceptibles d'être exposées au feu. Elle ne spécifie pas les formats normalisés des éléments en béton cellulaire autoclavé, les dimensions de fabrication courante, ni les caractéristiques angulaires des éléments de forme particulière et des éléments accessoires. Elle ne donne pas les tolérances dimensionnelles pour les éléments de forme particulière et les éléments accessoires. Elle ne couvre pas les produits destinés à servir d'assise anti-humidité ou de conduits intérieurs de fumée.
Specifikacija za zidake - 4. del: Zidaki iz avtoklaviranega celičnega betona
Ta evropski standard določa značilnosti in zahteve za zmogljivosti za zidake iz avtoklaviranega celičnega betona, ki so v glavnem predvideni za uporabo pri raznovrstnih nosilnih in nenosilnih aplikacijah pri vseh oblikah sten, vključno z enoslojnim zidom, votlim zidom, predelki, opornimi stenami, kletmi in splošno uporabo pod zemljo, ki vključuje stene za zaščito pred požarom, toplotno izolacijo, zvočno izolacijo in strukturo dimnikov (razen dimnih cevi). Opredeljuje zmogljivost v zvezi z npr. močjo, gostoto, dimenzijsko natančnostjo, itd. in zagotavlja oceno skladnosti proizvoda s tem evropskim standardom. Vključena je zahteva za označevanje proizvodov, ki jih zajema ta evropski standard. Ta evropski standard ne zajema zahtev za panele etažne višine, obloge dimnih cevi in zidake z vgrajenim materialom za toplotno izolacijo, vezanim na stranice zidaka, ki so lahko izpostavljene ognju. Ne določa standardnih velikosti za zidake iz avtoklaviranega celičnega betona niti ne določa standardnih delovnih dimenzij in kotov zidakov posebnih oblik in pomožnih zidakov. Ne podaja dovoljenih odstopanj za zidake posebnih oblik in pomožne zidake. Ne zajema proizvodov, ki se uporabljajo kot izolacijska zaščita pred vlago ali obloga dimnika.
