NBN EN 12150-1:2000

This European standard covers tolerances, flatness, edge work, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened soda lime silicate safety glass for use in buildings. Bent thermally toughened soda lime silicate safety glass is mentioned, but this product is not part of this standard. Other requirements not specified in this standard may apply to thermally toughened soda lime silicate safety glass which is incorporated into assemblies, e.g. laminated glass or insulating units, or undergo an additional treatment, e.g. coating, etc. Thermally toughened soda lime silicate glass, in this case, does not lose its mechanical or thermal characteristics.
