Glass in building - Heat soaked thermally toughened alkaline earth silicate safety glass - Part 1: Definition and description
This European Standard 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 not 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 EN 15682-2. In this case, heat soaked thermally toughened alkaline earth silicate glass does not lose its mechanical or thermal characteristics.
Glas im Bauwesen - Heißgelagertes thermisch vorgespanntes Erdalkali-Silicat-Einscheibensicherheitsglas - Teil 1: Definition und Beschreibung
Diese Europäische Norm legt das Heißlagerungsprozess-System sowie die Toleranzen der Geradheit, Kanten-bearbeitung, das Bruchverhalten und physikalische und mechanische Eigenschaften von flachem heißgelagertem thermisch vorgespanntem Erdalkali-Silicat-Einscheiben¬sicherheitsglas für die Verwendung im Bauwesen fest. Anhang B enthält Angaben zu gebogenem heißgelagertem thermisch vorgespanntem 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, EN 15682 2, 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
La présente Norme européenne 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, EN 15682-2. Dans ce cas, le verre de silicate alcalino-terreux trempé et traité Heat Soak ne perd pas ses caractéristiques mécaniques ou thermiques.
Steklo v gradbeništvu - HS-preskus kaljenega zemljoalkalijskega silikatnega varnostnega stekla - 1. del: Definicije in opis
Ta evropski standard določa sistem vročinske obdelave (HS) s toleranco, ploskostjo, obdelavo robov, drobljenjem ter fizičnimi in mehanskimi lastnostmi monolitnega ploskega HS-preskušenega kaljenega zemljoalkalijskega silikatnega varnostnega stekla, ki se uporablja v gradbeništvu. Informacije o ukrivljenem HS-preskušenem kaljenem zemljoalkalijskem silikatnem varnostnem steklu so podane v dodatku B, vendar ta izdelek ni del tega dokumenta. Druge zahteve, ki niso določene v tem dokumentu, se lahko uporabljajo za HS-preskušeno kaljeno zemljoalkalijsko silikatno varnostno steklo, ki je vgrajeno v sestave, npr. lepljeno steklo ali izolacijsko steklo, ali pa ga je treba dodatno obdelati, npr. z nanosi. Dodatne zahteve so določene v ustreznem standardu za izdelek EN 15682-2. HS-preskušeno kaljeno zemljoalkalijsko silikatno steklo v tem primeru ne izgubi mehanskih ali toplotnih lastnosti.

Key T glass temperature at any point, °C d ambient temperature t time, h a heating phase 1 first glass to reach 280 °C b holding phase 2 last glass to reach 280 °C c cooling phase Figure 1 — Heat soak process cycle 5.3.2 Heating phase The heating phase commences with all the glasses at ambient temperature and concludes when the surface temperature of the last glass reaches 280 °C. The time to reach this temperature is defined in the calibration process. This time will be dependent on the size of the oven, the amount of glass to be treated, the separation between glasses and the heating system capacity. The glass separation and rate of heating should be controlled to minimise the risk of glass breakage as a result of thermal stress. To facilitate economic heating, the air temperature within the oven may exceed 320 °C. However, the glass surface temperature shall not be allowed to exceed 320 °C. The period of glass surface temperature in excess of 300 °C shall be minimised. When the temperature of the glass exceeds 300 °C, care should be taken to ensure that the properties of the heat soaked thermally toughened alkaline earth silicate safety glass are not significantly altered, i.e. they continue to meet Clause 10. 5.3.3 Holding phase The holding phase commences when the surface temperature of all the glasses has reached a temperature of 280 °C. The duration of the holding phase is minimum 2 h. Precise oven control is necessary in order to ensure that the glass surface temperature shall be maintained in the range of 290 °C ± 10 °C during the holding phase. 5.3.4 Cooling phase The cooling phase commences when the last glass to reach 280 °C has completed its holding phase, i.e. been held for two hours at 290 °C ± 10 °C. During this phase the glass temperature shall be brought down to ambient temperature. SIST EN 15682-1:2013
Figure 2 — Example of a vertical glass support The minimum separation of the glasses shall be determined during the calibration of the oven (see 6.5 and Annex A). Generally, a minimum separation of 20 mm is recommended. See Figure 3. NOTE If glasses of very different sizes are put on the same stillage, they will require greater separation in order to prevent glass breakage when the furnace is opened after the heat soak process. The same applies to glasses with holes, notches and cut-outs. Dimensions in millimetres

It shall be made clear which dimension is the width, B, and which is the length, H, when related to its installed position. SIST EN 15682-1:2013

The sides of the prescribed rectangles are parallel to one another and these rectangles shall have a common centre (see Figure 5). The limits of squareness shall be determined by the prescribed rectangles. Tolerances are given in Table 2.
