Glass in building - Heat soaked thermally toughened alkaline earth silicate safety glass - Part 1: Definition and description

This document specifies the heat soak process system together with tolerances flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat heat soaked thermally toughened alkaline earth silicate safety glass for use in buildings.
Information on curved heat soak thermally toughened alkaline earth silicate safety glass is given in annex B, but this product does riot form part of this document.
Other requirements, not specified in this document, can apply to heat soaked thermally toughened alkaline earth silicate safety glass which is incorporated into assemblies, e.g. laminated glass or insulating units, or undergo an additional treatment, e.g. coating. The additional requirements are specified in the appropriate product standard. Heat soak thermally toughened alkaline earth silicate safety glass, in this case, does not lose its mechanical or thermal characteristics.

Glas im Bauwesen - Heißgelagertes thermisch vorgespanntes Erdalkali-Silicat-Einscheibensicherheitsglas - Teil 1: Definition und Beschreibung

Dieser Teil der EN 15682 legt das Heißlagerungsprozess-System sowie die Toleranzen der Geradheit, Kanten-bearbeitung, das Bruchverhalten und physikalische und mechanische Eigenschaften von einscheibigem, flachem heißgelagerten thermisch vorgespannten Erdalkali-Silicat-Einscheiben¬sicherheitsglas für die Verwendung im Bauwesen fest. Anhang B enthält Angaben zu gebogenem heißgelagerten thermisch vorgespannten Erdalkali-Silicat-Einscheiben¬sicherheitsglas, dieses Produkt ist jedoch nicht Bestandteil dieses Dokuments.
An heißgelagerte thermisch vorgespannte Erdalkali-Silicat-Einscheibensicherheitsgläser können andere Anforderungen, die in diesem Dokument nicht beschrieben sind, gestellt werden, wenn sie Bestandteil von Kombinationen sind, wie z. B. Verbundglas oder Isolierglas, sind oder wenn sie weiterverarbeitet, z. B. beschichtet werden. Die zusätzlichen Anforderungen sind in der zutreffenden Produktnorm festgelegt. In diesem Fall wird heißgelagertes thermisch vor¬gespanntes Erdalkali-Silicat-Einscheibensicherheitsglas seine mechanischen oder thermischen Eigenschaften nicht verlieren.

Verre dans la construction - Verre de silicate alcalinoterreux de sécurité trempé et traité Heat Soak - Partie 1: Définition et description

Le présent document spécifie le système fonctionnel de stabilisation thermique ainsi que les tolérances, la planéité, la finition des chants, la fragmentation et les caractéristiques physiques et mécaniques du verre plat monolithique de silicate alcalino-terreux de sécurité trempé et traité Heat Soak dans la construction.
L'Annexe B fournit des informations relatives au verre bombé de silicate alcalino-terreux de sécurité trempé et traité Heat Soak, mais ce produit ne fait pas partie de la présente norme.
D'autres exigences, non spécifiées dans le présent document, peuvent s'appliquer au verre de silicate alcalino-terreux de sécurité trempé et traité Heat Soak intégré dans des ensembles, par exemple du verre feuilleté ou des ensembles isolants préfabriqués scellés ou qui subit un traitement supplémentaire, par exemple une couche. Les exigences additionnelles sont spécifiées dans la norme de produit correspondante. Dans ce cas, le verre de silicate alcalino-terreux de sécurité trempé et traité Heat Soak ne perd pas ses caractéristiques mécaniques ou thermiques.
