Glass in building - Heat strengthened soda lime silicate glass - Part 1: Definition and description

This European Standard specifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat heat strengthened soda lime silicate glass of nominal thicknesses from 3 mm to 12 mm for use in buildings.
Information on curved heat strengthened soda lime silicate glass is given in Annex A, but this product does not form part of this standard.
Other requirements, not specified in this standard, can apply to heat strengthened soda lime silicate 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. Heat strengthened soda lime silicate glass, in this case, does not lose its mechanical or thermal characteristics.
This European Standard does not cover glass sandblasted after toughening.

Glas im Bauwesen - Teilvorgespanntes Kalknatronglas - Teil 1: Definition und Beschreibung

Diese Europäische Norm legt Toleranzen, Geradheit, Kantenbearbeitung, Bruchverhalten sowie physikalische und mechanische Eigenschaften von einscheibigem, flachem, teilvorgespanntem Glas mit Nenndicken von 3 mm bis 12 mm für den Gebrauch im Bauwesen fest.
An teilvorgespanntes Kalknatronglas können andere Anforderungen, die in dieser Norm 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 wird teilvorgespanntes Kalknatronglas seine mechanischen und/oder thermischen Eigenschaften nicht verlieren.
Diese Europäische Norm behandelt kein im Anschluss an das Teilvorspannen sandgestrahltes Glas.

Verre dans la construction - Verre de silicate sodo-calcique durci 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 de silicate sodo-calcique plat monolithique durci thermiquement, d’une épaisseur nominale de 3 mm à 12 mm, destiné à être utilisé dans la construction.
D’autres exigences, non spécifiées dans la présente norme, sont susceptibles de s’appliquer au verre de silicate sodo-calcique durci 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 de silicate sodo-calcique durci thermiquement ne perd pas ses caractéristiques mécaniques ou thermiques.
La présente Norme européenne ne traite pas du verre sablé après trempe.

Steklo v gradbeništvu - Delno kaljeno natrij-kalcijevo silikatno steklo - 1. del: Definicija in opis

Ta evropski standard določa toleranco, ploskost, obdelavo robov, drobljenje ter fizične in mehanske lastnosti monolitnega ploskega delno kaljenega natrij-kalcijevega silikatnega stekla nominalne debeline od 3 mm do 12 mm, ki se uporablja v gradbeništvu. Informacije o ukrivljenem delno kaljenem natrij-kalcijevem steklu so podane v dodatku A, vendar ta izdelek ni del tega standarda. Druge zahteve, ki niso določene v tem standardu, se lahko uporabljajo za delno kaljeno natrij-kalcijevo silikatno 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. Delno kaljeno natrij-kalcijevo silikatno steklo v tem primeru ne izgubi mehanskih ali toplotnih lastnosti.

6 Dimensions and tolerances
6.1 Nominal thickness and thickness tolerances The nominal thicknesses and thickness tolerances are those given in the relevant product standard (see Clause 4), some of which are reproduced in Table 1. Table 1 — Nominal thicknesses and thickness tolerances Dimensions in millimetres Nominal Thickness tolerances for glass type thickness d Float Patterned Drawn sheet New antique drawn sheet 3 ± 0,2 ± 0,5 ± 0,2 not manufactured 4 ± 0,2 ± 0,5 ± 0,2 ± 0,3 5 ± 0,2 ± 0,5 ± 0,3 not manufactured 6 ± 0,2 ± 0,5 ± 0,3 ± 0,3 8 ± 0,3 ± 0,8 ± 0,4 not manufactured 10 ± 0,3 ± 1,0 ± 0,5 not manufactured 12 ± 0,3 ± 1,5 ± 0,6 not manufactured
The thickness of a pane shall be determined as for the basic product. The measurement shall be taken at the centres of the 4 sides, and away from the area of any tong marks (see Figure 2), which may be present. SIST EN 1863-1:2012

Figure 1 — Examples of width, B, and length, H, relative to the pane shape NOTE For heat strengthened soda lime silicate glass manufactured from patterned glass, the direction of the pattern should be specified relative to one of the dimensions. 6.2.2 Maximum and minimum sizes For maximum and minimum sizes, the manufacturer should be consulted. 6.2.3 Tolerances and squareness The nominal dimensions for width and length being given, the finished pane shall not be larger than the nominal dimensions increased by the tolerance t, or smaller than the nominal dimensions reduced by the tolerance t. Limits are given in Table 2. The squareness of rectangular glass panes is expressed by the difference between its diagonals.
The difference between the two diagonal lengths of the pane of glass shall not be larger than the deviation limit v as specified in Table 3. Table 2 — Tolerances on width, B, and length, H Dimensions in millimetres Nominal dimension of side,
B or H Tolerance, t nominal glass thickness,
d ≤ 8 nominal glass thickness, d > 8 ≤ 2 000 ± 2,0 ± 3,0 2 000 < B or H ≤ 3 000 ± 3,0 ± 4,0 > 3 000 ± 4,0 ± 5,0
d > 8 ≤ 2 000 ≤ 4 ≤ 6 2 000 < B or H ≤ 3 000 ≤ 6 ≤ 8 > 3 000 ≤ 8 ≤ 10
6.2.4 Edge deformation produced by the vertical process The tongs used to suspend the glass during heat strengthening result in surface depressions, known as tong marks (see Figure 2). The centres of the tong marks are situated up to a maximum of 20 mm in from the edge. A deformation of the edge less than 2 mm can be produced in the region of the tong mark and there may also be an area of optical distortion. These deformations are included in the tolerances in Table 2.

This difference in flatness depends on the type of glass, e.g. coated, patterned etc., glass dimensions, i.e. the nominal thickness, the dimensions and the ratio between the dimensi
