Glass in building - Thermally toughened borosilicate safety glass - Part 1: Definition and description
This European Standard specifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened borosilicate safety glass for use in buildings.
Information on curved thermally toughened borosilicate safety glass is given in annex B, but this product does not form part of this standard.
Other requirements, not specified in this standard, may apply to thermally toughened borosilicate 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. Thermally toughened borosilicate safety glass, in this case, does not lose its mechanical or thermal characteristics.
Glas im Bauwesen - Thermisch vorgespanntes Borosilicat-Einscheiben-Sicherheitsglas - Teil 1: Definition und Beschreibung
Diese Europäische Norm beinhaltet Grenzabmaße, Geradheit, Kantenbearbeitung, Bruchverhalten und physikalische und mechanische Eigenschaften von flachem, thermisch vorgespanntem Borosilicat-Einscheiben-Sicherheitsglas für die Verwendung im Bauwesen. Gebogenes thermisch vorgespanntes Borosilicat-Einscheiben-Sicherheitsglas ist zwar erwähnt, aber nicht Bestandteil dieser Norm. Thermisch vorgespanntes Borosilicat-Einscheiben- Sicherheitsglas, wie es nachfolgend definiert wird, kann Bestandteil sein von Kombinationen wie z.B. Verbundglas, Isolierglas usw.
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 a etre utilisé dans la construction.
Des renseignements sont donnés dans l'annexe B sur le verre borosilicate de sécurité bombé trempé thermiquement, mais ce produit ne fait pas partie de la présente norme.
D'autres exigences, non spécifiées dans la présente norme, peuvent s'appliquer au verre borosilicate de sécurité trempé thermiquement intégré dans des ensembles, par exemple des ensembles isolants ou en verre feuilleté, ou subissant un traitement supplémentaire, par exemple la dépose d'une couche. 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.

EN 13024-1:2002 (E)5IntroductionThermally toughened borosilicate safety glass has a higher thermal shock resistance and a saferbreakage behaviour when compared with annealed glass.
When it should be used to offer protectionunder accidental human impact, thermally toughened borosilicate safety glass also should be classifiedaccording to prEN 12600.NOTE
CEN/TC129/WG8 is producing standards for the determination of the design strength of glass and ispreparing a design method.NOTE
CEN/TC129/WG2 is preparing a standard for production control and evaluation of conformity.1ScopeThis European Standard specifies tolerances, flatness, edgework, fragmentation and physical andmechanical characteristics of monolithic flat thermally toughened borosilicate safety glass for use inbuildings.Information on curved thermally toughened borosilicate safety glass is given in annex B, but thisproduct does not form part of this standard.Other requirements, not specified in this standard, can apply to thermally toughened borosilicate safetyglass which is incorporated into assemblies, e.g. laminated glass or insulating units, or undergo anadditional treatment, e.g. coating.
The additional requirements are specified in the appropriate productstandard.
Thermally toughened borosilicate safety glass, in this case, does not lose its mechanical orthermal characteristics.2Normative ReferencesThis European Standard incorporates by dated or undated reference, provisions from other publications.These normative references are cited at the appropriate places in the text, and the publications are listedhereafter. For dated references, subsequent amendments to or revisions of any of these publicationsapply to this European Standard only when incorporated in it by amendment or revision. For undatedreferences, the latest edition of the publication referred to applies (including amendments).EN 673, Glass in building – Determination of thermal transmittance (U value) – Calculation method.EN 1096-1, Glass in building – Coated glass – Part 1: Definitions and classification.EN 1748-1, Glass in building – Special Basic Products – Part 1: Borosilicate glasses.prEN 12600, Glass in building - Pendulum test - Impact test method for flat glass and performancerequirements.SIST EN 13024-1:2004
EN 13024-1:2002 (E)63Terms and definitionsFor the purposes of this European Standard the following terms and definitions apply.3.1thermally toughened borosilicate safety glassglass within which a permanent surface compressive stress has been induced by a controlled heating andcooling process in order to give it greatly increased resistance to mechanical and thermal stress andprescribed fragmentation characteristics3.2flat thermally toughened borosilicate safety glassthermally toughened borosilicate safety glass which has not been deliberately given a specific profileduring manufacture3.3enamelled thermally toughened borosilicate safety glassthermally toughened borosilicate safety glass which has a ceramic frit fired into the surface during thetoughening process. After toughening the ceramic frit becomes an integral part of the glassNOTE
In the UK, this glass is also known as opaque thermally toughened borosilicate safety glass.3.4horizontal tougheningprocess in which the glass is supported on horizontal rollers3.5vertical tougheningprocess in which the glass is suspended by tongs4Glass productsThermally toughened borosilicate safety glass is made from a monolithic glass generally correspondingto one of the following standards:- borosilicate glass according to EN 1748-1- coated glass according to EN 1096-1Other nominal thicknesses of glass than those covered in the above standards are possible.5Fracture characteristicsIn the event of breakage, thermally toughened borosilicate safety glass fractures into numerous smallpieces, the edges of which are generally blunt.NOTE
Fragmentation in service does not always correspond to that described in clause 8, due to restraint fromfixing or reprocessing (e.g. laminating), or due to the cause of fracture.SIST EN 13024-1:2004

EN 13024-1:2002 (E)8The thickness of a pane shall be determined as for the basic product.
The measurement shall be takenat the centres of the 4 sides, and away from the area of any tong marks (see Figure 3), which may bepresent.NOTE:Table 1a corresponds to EN 1748-1. Table 1b diverges from this standard. Meanwhile it is possibleto produce borosilicate float glass in the same thicknesses and tolerances as soda lime silicate floatglass. This fact is taken into account in this standard. EN 1748-1 will be revised.6.2Width and length (sizes)6.2.1GeneralWhen thermally toughened borosilicate safety glass dimensions are quoted for rectangular panes, thefirst dimension shall be the width, B, and the second dimension the length, H, as shown in Figure 1. Itshall be made clear which dimension is the width, B, and which is the length, H, when related to itsinstalled position.Figure 1 - Examples of width, B, and length, H, relative to the pane shape6.2.2Maximum and minimum sizesFor maximum and minimum sizes, the manufacturer should be consulted.6.2.3Tolerances and squarenessThe nominal dimensions for width and length being given, the finished pane shall not be larger than aprescribed rectangle resulting from the nominal dimensions increased by the tolerance, t, or smaller thana prescribed rectangle reduced by the tolerance, t.
The sides of the prescribed rectangles are parallel toHHBBSIST EN 13024-1:2004
