Glass in building - Thermally toughened borosilicate safety glass - Part 1: Definition and description
This document specifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened borosilicate safety glass for use in buildings.
This standard deals exclusively with thermally toughened borosilicate safety glass manufactured by the horizontal toughening process.
Other requirements, not specified in this document, can apply to thermally toughened borosilicate safety glass which is incorporated into assemblies, e.g. laminated glass or insulating glass units, or undergo an additional treatment, e.g. coating. The additional requirements are specified in the appropriate product standard. Thermally toughened borosilicate safety glass, in this case, does not lose its mechanical or thermal characteristics and its resistance to temperature differentials.
Surface finished glasses (e.g. sandblasted, acid etched) after toughening are not covered by this document.
Glas im Bauwesen - Thermisch vorgespanntes Borosilicat-Einscheibensicherheitsglas - Teil 1: Definition und Beschreibung
Dieses Dokument legt die Grenzabmaße, Geradheit, Kantenbearbeitung, das Bruchverhalten und physikalische und mechanische Eigenschaften von einscheibigem, flachem, thermisch vorgespanntem Borosilicat-Einscheibensicherheitsglas für die Verwendung im Bauwesen fest.
Diese Norm behandelt ausschließlich thermisch vorgespanntes Borosilicat-Einscheibensicherheitsglas, das im horizontalen Vorspannverfahren hergestellt wird.
An thermisch vorgespannte Borosilicat-Einscheibensicherheitsgläser können andere Anforderungen, die in diesem Dokument nicht beschrieben sind, gestellt werden, wenn sie Bestandteil sind von Kombinationen wie z. B. Verbundglas, Isolierglas oder wenn sie weiterverarbeitet werden, z. B. beschichtet. Die zusätzlichen Anforderungen sind in den entsprechenden Normen der Fertigprodukte festgelegt. In diesem Fall verliert thermisch vorgespanntes Borosilicat-Einscheibensicherheitsglas seine mechanischen oder thermischen Eigenschaften oder seine Beständigkeit gegen Temperaturunterschiede nicht.
Gläser, die nach dem Vorspannen oberflächenbearbeitet werden (z. B. durch Sandstrahlen oder Säureätzung), fallen nicht in den Anwendungsbereich dieser Norm.
Verre dans la construction - Verre borosilicate de sécurité trempé thermiquement - Partie 1: Définition et description
La présente Norme européenne spécifie les tolérances, la planéité, la finition des chants, la fragmentation et les caractéristiques physiques et mécaniques du verre plat monolithique borosilicate de sécurité, trempé thermiquement, destiné à être utilisé dans la construction.
La présente norme traite exclusivement du verre borosilicate de sécurité trempé thermiquement fabriqué par le procédé de trempe horizontale.
D’autres exigences, non spécifiées dans la présente Norme européenne, sont susceptibles de s’appliquer au verre borosilicate de sécurité trempé thermiquement intégré dans des ensembles, par exemple des ensembles en verre feuilleté ou des vitrages isolants, ou de subir un traitement supplémentaire, par exemple un revêtement. Les exigences supplémentaires sont spécifiées dans la norme de produit correspondante. Dans ce cas, le verre borosilicate de sécurité trempé thermiquement ne perd pas ses caractéristiques mécaniques ou thermiques ni sa résistance aux températures différentielles.
Les verres dont la surface est finie (par exemple par sablage, gravure à l’acide) après trempe ne sont pas couverts par la présente Norme européenne.

Introduction
Thermally toughened borosilicate safety glass has a higher thermal shock resistance and a safer
breakage behaviour when compared with annealed glass. When it should be used to offer protection
under accidental human impact, thermally toughened borosilicate safety glass should also be classified
according to EN 12600.
