This European Standard specifies tolerances, flatness of web and flanges, flange deviation, edgework, fragmentation and physical and mechanical characteristics of monolithic thermally toughened soda lime silicate channel shaped safety glass for use in buildings.
Other requirements, not specified in this document, can apply to thermally toughened soda lime silicate channel shaped safety glass, which undergoes an additional treatment, e.g. coating. The additional requirements are specified in the appropriate product standard EN 15683-2. Thermally toughened soda lime silicate channel shaped safety glass, in this case, does not lose its mechanical or thermal characteristics.
