This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 129.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

European foreword
This document (prEN 13024-1:2018) 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 will supersede EN 13024-1:2011.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
In comparison with the previous edition, the following technical modifications have been made:
a) Clause 1 has been revised;
b) Clause 3 has been re-sorted (to agree with EN 12150-1:2015);
c) Clause 5 has been revised;
d) Clause 6.1, Table 1 with nominal thicknesses has been revised. Some thicknesses have been
changed and some thicknesses have been deleted. Drawn sheet, rolled and cast glass is no longer
included as they have been deleted from standard of the special basic glass prEN 1748-1-1:2017;
e) Clause 6.3.2 has been revised;
f) Title of Clause 6.3.3 has been revised;
g) Table 8 has been revised;
h) Clause “Bibliography” has been deleted.
EN 13024 is divided into the following parts:
— EN 13024-1, Glass in building — Thermally toughened borosilicate safety glass — Part 1: Definition
and description;
— EN 13024-2, Glass in building — Thermally toughened borosilicate safety glass — Part 2: Product
standard.
This document contains other aspects of importance for trade.

Introduction
Thermally toughened borosilicate safety glass has a higher thermal shock resistance and a safer
breakage behaviour when compared with annealed glass. When it should be used to offer protection
under accidental human impact, thermally toughened borosilicate safety glass should also be classified
according to EN 12600.

1 Scope
This document specifies tolerances, flatness, edgework, fragmentation and physical and mechanical
characteristics of monolithic flat thermally toughened borosilicate safety glass for use in buildings.
This standard deals exclusively with thermally toughened borosilicate safety glass manufactured by the
horizontal toughening process.
Other requirements, not specified in this document, can apply to thermally toughened borosilicate
safety glass which is incorporated into assemblies, e.g. laminated glass or insulating glass units, or
undergo an additional treatment, e.g. coating. The additional requirements are specified in the
appropriate product standard. Thermally toughened borosilicate safety glass, in this case, does not lose
its mechanical or thermal characteristics and its resistance to temperature differentials.
Surface finished glasses (e.g. sandblasted, acid etched) after toughening are not covered b
