Foreword
This document (prEN 15683-1:2012) 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).
EN 15683, Glass in building — Thermally toughened soda lime silicate channel shaped safety glass, consists
of the following parts:
 Part 1: Definition and description;
 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 part of EN 15683 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 prEN 15683-2:2012. Thermally toughened
soda lime silicate channel shaped safety glass, in this case, does not lose its mechanical or thermal
characteristics.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.
EN 572-1, Glass in building — Basic soda lime silicate glass products – Part 1: Definitions and general
physical and mechanical properties
EN 572-7:2004, Glass in building — Basic soda lime silicate glass products — Part 7: Wired or unwired
channel shaped glass
EN 1288-4, Glass in building — Determination of the bending strength of glass — Part 4: Testing of channel
shaped glass
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
Note 1 to entry: The mechanical properties, i.e. thermal durability and mechanical strength, and safety properties, i.e.
fragmentation characteristics, are generated by the level of surface compression. These properties are not size
dependent.
3.2
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 becoming an integral part of the glass after toughening
3.3
horizontal toughening
process in which the glass is supported on horizontal rollers

4 Glass products
Thermally toughened soda lime silicate channel shaped safety glass shall be made from a monolithic glass
generally corresponding to the following standard:
 basic soda lime silicate glass products – unwired channel shaped glass according to EN 572-1 and
EN 572-7;
 this may also be coated in accordance with EN 1096-1.
5 Fracture characteristics
In the event of breakage, thermally toughened soda lime silicate channel shaped safety glass fractures into
numerous small pieces, the edges of which are generally blunt.
NOTE Fragmentation in service does not always correspond to that described in Clause 8, due to restraint from fixing
or due to the cause of fracture.
6 Dimensions and tolerances
6.1 General
The dimensions of thermally toughened soda lime silicate channel shaped safety glass are shown in Figure 1.
These are glass thickness (c), width (B), length (H) and flange height (d).
6.2 Dimensions and dimensional tolerances
6.2.1 Nominal thickness (c) and
