Specification for masonry units - Part 5: Manufactured stone masonry units
This EN specifies the characteristics and performance requirements of Manufactured Stone Masonry Units for which the main intended uses are facing or exposed masonry in loadbearing or non-loadbearing building and civil engineering applications. The units are suitable for all forms of coursed or random masonry walling, including single leaf, cavity, partition, retaining and the external masonry to chimneys and they can provide fire protection, thermal insulation, sound insulation and sound absorption.
Festlegungen für Mauersteine - Teil 5: Betonwerksteine
Diese Europäische Norm beschreibt die Eigenschaften und Leistungsanforderungen für Betonwerksteine, die vorwiegend für tragendes und nichttragendes Sicht- oder Verblendmauerwerk in Bauwerken des Hoch- und Tiefbaus verwendet werden. Diese Steine sind für alle Arten von Schichtenmauerwerk oder unregelmäßigem Mauerwerk einschließlich einschaligen Mauerwerks, zweischaligen Mauerwerks, Trennwänden, Stützmauern und Außenmauer-werk von Schornsteinen geeignet. Sie können dem Brandschutz, dem Wärmeschutz und dem Schallschutz dienen.
Diese Norm gilt für Betonwerksteine, die so durch Gießen oder Pressen hergestellt werden, dass sie Naturstein ähneln. Die Oberflächen von Betonwerksteinen sind glatt oder strukturiert, z. B. durch Formen, Spalten, Waschen, Sprengen oder Stocken hergestellt und mit gleichen oder unterschiedlichen Ansichten gestaltet. Die Norm gilt für Mauersteine, die einheitlich aus dem gleichen Beton hergestellt sind und für solche, deren seitliche Außenwandungen aus anderen Betonmischungen bestehen. Sie gilt nicht für Mauersteine, deren Außenseiten mit dekorativen Bekleidungen beklebt sind. Mauersteine, die den Anforderungen von prEN 771-3 entsprechen, sind nicht Gegenstand dieser Norm.
Diese Norm beschreibt die Anforderungen, z.B. an Festigkeit, Rohdichte, Maßgenauigkeit und Aussehen. Ferner werden die Konformitätsbewertung und die Kennzeichnung der von dieser Europäischen Norm erfassten Produkte festgelegt.
Diese Europäische Norm gilt nicht für geschosshohe Tafeln, für Mauersteine für die Auskleidung von Rauchabzügen, für Steine mit aufgeklebten, dekorativen Bekleidungen und nicht für Produkte zur Herstellung feuchtesperrender Schichten. Sie enthält keine genormten Größen für Betonwerksteine und keine Sollmaße oder Winkel für Formsteine. Diese Europäische Norm gilt nicht für Steine mit einem Wärmedämmstoff, der auf die Seiten des Steins, die Feuer ausgesetzt sein können, aufgebracht ist.
Spécifications pour éléments de maçonnerie - Partie 5: Eléments de maçonnerie en pierre reconstituée en béton
La présente Norme européenne définit les caractéristiques et les exigences de performances des éléments de maçonnerie en pierre reconstituée en béton utilisés, exposés ou non, principalement en maçonnerie de parement, porteuse ou non, dans des bâtiments ou des ouvrages de génie civil. Ces éléments conviennent à toutes les formes de murs de maçonnerie appareillée ou non, y compris les murs à simple et double paroi, les cloisons, les murs de soutènement et la maçonnerie extérieure de conduits de fumée. Ils peuvent constituer une protection contre les incendies, une isolation thermique ou acoustique et assurer l'absorption des bruits.
La présente norme traite des éléments de maçonnerie en béton fabriqués en vue d'imiter la pierre naturelle, en mettant en �uvre des techniques de moulage ou de compression avec ou sans surfaces structurées obtenues, par exemple, par moulage, fendage, lavage, sablage ou usinage et avec ou sans effets de géométrie variable. Elle traite des éléments de maçonnerie mono-béton ainsi que de ceux constitués de bétons bi-couche mais exclut les éléments fabriqués avec une face décorative collée. La présente norme ne concerne pas les éléments de maçonnerie destinés à être conformes à l'EN 771-3.
Elle définit, d'une part, les performances relatives, par exemple, à la résistance, à la masse volumique, aux tolérances dimensionnelles, à l'aspect de surface et permet, d'autre part, d'évaluer la conformité du produit à la présente Norme européenne. Elle inclut également les exigences de marquage des produits dont elle traite.
La présente Norme européenne ne couvre pas les panneaux hauteur d'étage, les éléments de maçonnerie utilisés pour les conduits intérieurs de fumée ni ceux fabriqués avec une face décorative collée. Elle ne traite pas des produits destinés à servir de barrière d'étanchéité et ne préconise pas non plus les dimensions normalisées des éléments de maçonnerie en pierre reconstituée en béton, les dimensions de fabrication, ni les caracté

1 Scope
This European Standard specifies the characteristics and performance requirements of manufactured
stone masonry units for which the main intended uses are facing or exposed masonry in load bearing
or non-load bearing building and civil engineering applications. The units are suitable for all forms of
coursed or random masonry walling, including single leaf, cavity, partition, retaining and the external
masonry to chimneys. They can provide fire protection, thermal insulation, sound insulation and
sound absorption.
This standard covers concrete masonry units manufactured to resemble natural stone using casting or
pressing techniques with or without textured surfaces produced, by casting, splitting, washing,
blasting or tooling and with or without variable outline effects. It covers homogeneous masonry units
and those consisting of different facing and backing concrete mixes but excludes those manufactured
with an adhesive bonded decorative face. This standard does not cover masonry units intended to
conform to EN 771-3.
It defines the performance related to e.g. strength, density, dimensional accuracy, surface
appearance and provides for the evaluation of conformity of the product to this European Standard.
The marking requirements for products covered by this European Standard are also included.
This European Standard does not apply to storey height panels, masonry units used for chimney flues
or units manufactured with an adhesive bonded decorative face. It does not include products intended
to be used as a damp proof course nor does it specify standard sizes for manufactured stone
masonry units or work dimensions and angles of specially shaped units. It does not cover units with
an incorporated thermal insulation material bonded to the faces of the unit susceptible to be exposed
to fire.
