DIN EN 14179-1:2016-12

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 soda lime silicate safety glass for use in buildings. Annex B contains information on curved heat soaked thermally toughened soda lime silicate safety glass, but this product is not part of this European Standard. Other requirements, not specified in this European Standard, can apply to heat soaked thermally toughened soda lime silicate safety glass which is incorporated into assemblies, such as laminated glass or insulating units, or undergo an additional treatment, for example coating. The additional requirements are specified in the appropriate product standard. Heat soaked 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 (for example, sandblasted, acid etched) after toughening are not covered by this European Standard.
