Glass in building. Thermally toughened soda lime silicate safety glass – Definition and description
| Published By | Publication Date | Number of Pages |
| BSI | 2019 | 38 |
This European Standard specifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened soda lime silicate safety glass for use in buildings.
Information on curved thermally toughened soda lime silicate safety glass is given in Annex A, but this product does not form part of this European Standard.
Other requirements, not specified in this European Standard, can apply to thermally toughened soda lime silicate 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 glass product standard. Thermally toughened soda lime silicate safety glass, in this case, does not lose its bending strength characteristics and its resistance to temperature differentials.
Surface finished glasses (e.g. sandblasted, acid etched) after toughening are not covered by this European Standard.
