Foreword
This document (prEN 15683-1:2007) has been prepared by Technical Committee CEN/TC 129 “Glass in
building”, the secretariat of which is held by NBN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
This document has been prepared under a mandate given to CEN by the European Commission and the

No existing document is superseded.
This Part of the European Standard does not stand alone, it is a part of one standard:
– prEN 15683-1: Glass in building – Thermally toughened soda lime silicate channel shaped safety glass –
Part 1: Definition and description;
– prEN 15683-2: Glass in building – Thermally toughened soda lime silicate channel shaped safety glass –
Part 2: Evaluation of conformity/Product standard.
Introduction
Thermally toughened soda lime silicate channel shaped safety glass has a safer breakage behaviour when
compared with annealed glass.
1 Scope
This document 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. Thermally toughened soda lime silicate channel shaped safety
glass, in this case, does not lose its mechanical or thermal characteristics.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
thermally toughened soda lime silicate channel shaped safety glass
glass within which a permanent surface compressive stress has been induced by a controlled heating and
cooling process in order to give it greatly increased resistance to mechanical and thermal stress and
prescribed fragmentation characteristics
3.3
enamelled thermally toughened soda lime silicate channel shaped safety glass
thermally toughened soda lime silicate channel shaped safety glass which has a ceramic frit fired into the
surface during the toughening process. After toughening the ceramic frit becomes an integral part of the glass
