DIN EN 12337-1:2000-11

The document specifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of flat chemically strengthened glass for use in buildings. Chemically strengthened glass, as defined in the document, can be incorporated into assemblies e.g. laminated glass or insulating units, or undergo an additional treatment, e.g. coating, and will therefore also comply with the requirements of the appropriate finished product standard.
