Introduction
Heat soaked thermally toughened soda lime silicate safety glass has a safer breakage behaviour when
compared with annealed glass. It also has a known level of residual risk of spontaneous breakage arising from
the possible presence of critical nickel sulphide (NiS) inclusions in the thermally toughened soda lime silicate
glass.
NOTE 1 This case deals with extremely large quantities of glass. These quantities are dealt with on a statistical basis.
Therefore it is impossible to select a quantity of heat soaked thermally toughened soda lime silicate safety glass, for a
building, and claim that ‘no break’ by NiS inclusion can occur. The breakage of heat soaked thermally toughened soda
lime silicate safety glass caused by other influences is excluded.[sl1]
When used to offer protection under accidental human impact, heat soaked thermally toughened soda lime
silicate safety glass also should be classified according to EN 12600 (all parts).
NOTE 2 CEN/TC 129/WG 8 is producing standards for the determination of the design strength of glass and is
preparing a design method.

4 Glass products
Heat soaked thermally toughened soda lime silicate safety glass shall be made from a monolithic soda lime
silicate glass product generally corresponding to one of the following standards:
soda lime silicate glass according to EN 572-1;
float glass according to EN 572-2;
drawn sheet glass according to EN 572-4;
patterned glass according to EN 572-5;
coated glass according to EN 1096-1.
5 Manufacturing processes
5.1 General
Heat soaked thermally toughened soda time silicate safety glass is manufactured as follows:
Basic soda lime silicate glass products (see Clause 4) are cut to size, shaped and edgeworked (see Clause 9).
The prepared glass panes are then thermally toughened (see 5.2).
The thermally toughened panes are then subjected to the heat soak process cycle.
After manufacture the heat soaked thermally toughened soda lime silicate glass shall comply with the
fragmentation test (see Clause 10) and mechanical strength requirement (see 11.4).
5.2 Toughening process
The cut, shaped and edgeworked glasses are toughened. The horizontal or vertical toughened glass shall
comply with the flatness criteria (see 8.3).
The thermally toughened soda lime silicate glass shall have a level of fragmentation that will ensure that after
the glass has been through the heat soak process, and subsequently tested to the fragmentation test (see
Clause 10), it shall comply with 10.5.
5.3 Heat soak process cycle
5.3.1 General
The heat soak process cycle consists of a heating phase, a holding phase and a cooling phase (see Figure 1).
Key
T glass temperature at any point, °C d ambient temperature
t time, h
a heating phase
1 first glass to reach 280 °C b holding phase
2 last glass to reach 280 °C c cooling phase
Figure 1 — Heat soak process cycle
5.3.2 Heating phase
The heating phase commences with all the glasses at ambient temperature and concludes when the surface
temperature of the last glass reaches 280 °C. The time to reach this temperature is defined in the calibration
process. This time will be dependent on the size of the oven, the amount of glass to be treated, the separation
between glasses and the heating system capacity.
NOTE 1 The glass separation and rate of heating should be controlled to minimise the risk of glass breakage as a
result of thermal stress.
To facilitate economic heating, the air temperature within the oven may exceed 320 °C. However, the glass
surface temperature shall not be allowed to exceed 320 °C. The period of glass surface temperature in excess
of 300 °C shall be minimised.
NOTE 2 When the temperature of the glass exceeds 300 °C, care should be taken to ensure that the properties of the
heat soaked thermally toughened soda lime silicate safety glass are not significantly altered i.e. they continue to meet
Clause 10.
5.3.3 Holding phase
The holding phase commences when the surface temperature of all the glasses has reached a temperature of
280 °C. The duration of the holding phase is 2 h.
Precise oven control is necessary in order to ensure that the glass surface temperature shall be maintained in
the range of 290 °C ± 10 °C during the holding phase.
5.3.4 Cooling phase
The cooling phase commences when the last glass to reach 280 °C has completed its holding phase, i.e.
been held for two hours at 290 °C ± 10 °C. During this phase the glass temperature shall be brought down to
ambient temperature.
The cooling phase can be concluded when the air temperature in the oven reaches 70 °C.
NOTE The rate of cooling should be controlled to minimise the risk of glass breakage as a result of thermal stress.
6 Heat soak process system
6.1 General
The heat soak process system consists of:
oven (see 6.2);
glass support (see 6.3);
separation system (see 6.4).
The oven shall be calibrated, see 6.5 and Annex A, and this determines the method of operation of the heat
soak process system during manufacture of heat soaked thermally toughened soda lime silicate safety glass.
6.2 Oven
The oven shall be heated by convection and shall allow an unhindered air circulation around each glass pane.
In the event of glass breakage the airflow shall not be hindered. The airflow in the oven shall be led parallel to
the glass surfaces.
NOTE The openings for the air ingress/egress should be designed to ensure that fragments of broken glass do not
cause blockages.
6.3 Glass support
Glasses may be supported vertically or horizontally. The glasses shall not be fixed or clamped, they have to
be supported to allow free movement.
NOTE Vertically means true vertical or up to 15° either side of true vertical.
The distance between glasses affects the airflow, heat exchange and the heating time. Glass to glass contact
shall not be allowed.
6.4 Glass separation
The glasses shall be separated in a manner that does not hinder the airflow. The separators shall also not
hinder the airflow e.g. see Figure 2.
Dimensions in millimetres
Figure 2 — Example of a vertical glass support
The minimum separation of the glasses shall be determined during the calibration of the oven, see 6.5 and
Annex A.
NOTE 1 Generally, a minimum separation of 20 mm is recommended (see Figure 3).
NOTE 2 If glasses of very different size are put on the same stillage, they will require greater separation in order to
prevent glass breakage when the furnace is opened alter the heat soak process. The same applies to glasses with holes,
notches and cut-outs.
Figure 3 — Recommend separation between glass
The positioning of the separators, material of the manufacture and their shape shall be specified during the
calibration test of the oven and shall be reproduced during the manufacturing process.
6.5 Calibration
The heat soak system, e.g. oven, glass separation, separators, etc., shall be calibrated, see Annex A.
The calibration shall determine the heating phase of the process, glass separation distance, the positioning,
material and shape of separators, the type and positioning of stillage(s) and define the operating conditions for
use during manufacture.
7 Fracture characteristics
In the event of breakage, heat soaked thermally toughened soda lime silicate 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 10, due to restraint from
fixing or reprocessing (e.g. laminating), or due to the cause of fracture.
8 Dimensions and tolerances
8.1 Nominal thickness and thickness tolerances
The nominal thicknesses and thickness tolerances are those given in the relevant product standard (see
Clause 4), some of which are reproduced in Table 1.

The thickness of a pane shall be determined as for the basic product. The measurement shall be taken at the
centres of the 4 sides, and away from the area of any tong marks (see Figure 6), which may be present.
8.2 Width and length (sizes)
8.2.1 General
When heat soaked thermally toughened soda lime silicate safety glass dimensions are quoted for rectangular
panes, the first dimension shall be the width, B, and the second dimension the length, H, as shown in
Figure 4. It shall be made clear which dimension is the width, B, and which is the length, H, when related to its
installed position.
Figure 4 — Examples of width, B, and length, H, relative to the pane shape
NOTE For heat soaked thermally toughened soda lime silicate safety glass manufactured from patterned glass, the
direction of the pattern should be specified relative to one of the dimensions.
8.2.2 Maximum and minimum sizes
For maximum and minimum sizes, the manufacturer shall be consulted.
8.2.3 Tolerances and squareness
The nominal dimensions for width and length being given, the finished pane shall not be larger than a
prescribed rectangle resulting from the nominal dimensions increased by the tolerance, t, or smaller than a
prescribed rectangle reduced by the tolerance, t. The sides of the prescribed rectangles are parallel to one
another and these rectangles shall have a common centre (see Figure 5). The limits of squareness shall be
determined by the prescribed rectangles. Tolerances are given in Table 2.

8.2.4 Edge deformation produced by vertical toughening
The tongs used to suspend the glass during toughening can result in surface depressions, known as tong
marks (see Figure 6). The centres of the tong marks may be situated up to a maximum of 20 mm in from the
edge. A deformation of the edge less than 2 mm can be produced in the region of the tong mark and there can
also be an area of optical distortion. These deformations shall be included in the tolerances in Table 2.

8.3 Flatness
8.3.1 General
By the very nature of the toughening process, it is not possible to obtain a product as flat as annealed glass.
The difference depends on the nominal thickness, the dimensions and the ratio between the dimensions.
Therefore a distortion known as overall bow may occur. There are two kinds of bow (see Figure 7):
overall or general bow;
local bow.
NOTE 1 Overall bow can, in general, be accommodated by the framing system.
NOTE 2 Local bow needs to be allowed for in the glazing materials and the weather seals. For special requirements
the manufacturers should be consulted.

The EN 14179-1:2005 standard provides a comprehensive framework for the heat soak process system specifically tailored to monolithic flat heat soaked thermally toughened soda lime silicate safety glass used in building applications. The scope of this standard is well-defined, encompassing critical parameters such as tolerances for flatness, edgework, fragmentation, as well as detailing the physical and mechanical characteristics essential for ensuring safety and performance in construction. One of the significant strengths of EN 14179-1:2005 lies in its rigorous specification of the heat soak process, which enhances the safety and durability of thermally toughened glass. By clearly outlining the requirements and tolerances, the standard facilitates a consistent approach to quality assurance in the manufacturing process. This is particularly important for ensuring that the safety glass meets the necessary safety regulations and provides adequate protection in a building environment. Additionally, the relevance of this standard extends beyond just the product itself; it serves as a foundational document for manufacturers looking to integrate heat soaked thermally toughened soda lime silicate safety glass into complex assemblies, such as laminated glass or insulating units. The acknowledgment of the possibility for additional treatments and the reference to relevant product standards further underscores its adaptability in various applications. While the document includes information on curved heat soak thermally toughened soda lime silicate safety glass in Annex B, it clearly delineates that this product is not included within the core specification. This precision helps in avoiding ambiguities and maintains focus on the primary subject of the standard. In summary, the EN 14179-1:2005 standard offers a detailed and relevant guideline for the specification and quality of heat soaked thermally toughened soda lime silicate safety glass for building applications, making it an essential resource for manufacturers and stakeholders in the construction industry.
Die Norm EN 14179-1:2005 definiert und beschreibt den Prozess zur Herstellung von wärmebehandeltem, thermisch vorgespanntem Sicherheitsglas aus Natron-Kalk-Silikat für den Einsatz im Bauwesen. Die umfangreiche Regelung berücksichtigt wesentliche Parameter wie die Toleranzen in Bezug auf Planheit, Kantenbearbeitung, Fragmentierung sowie die physikalischen und mechanischen Eigenschaften des Monoglas. Ein herausragendes Merkmal dieser Norm ist ihre spezifische Fokussierung auf die Wärmebehandlungsverfahren, die für eine signifikante Verbesserung der Sicherheit und der strukturellen Eigenschaften von Glasprodukten sorgen. Durch die Etablierung eines klaren Rahmenwerks wird sichergestellt, dass die thermisch vorgespannten Gläser eine hohe Qualität und Zuverlässigkeit aufweisen, was insbesondere für Bauanwendungen von großer Bedeutung ist. Des Weiteren ist die Norm besonders relevant, da sie die Möglichkeit eröffnet, zusätzliche Anforderungen zu berücksichtigen, die für wärmebehandeltes Glas, welches in Verbundsysteme integriert wird oder zusätzlichen Behandlungen unterzogen wird, gelten können. Dies gewährleistet eine optimale Anpassung an spezifische Projektanforderungen, ohne dabei die mechansichen und thermischen Eigenschaften des Glases zu beeinträchtigen. Somit bietet die EN 14179-1:2005 eine solide Grundlage für die Verwendung von wärmebehandeltem, thermisch vorgespanntem Natron-Kalk-Silikatsicherheitsglas, und fördert die Sicherheit und Leistungsfähigkeit in Bauprojekten erheblich.

Cela montre une approche complète de la norme, en reconnaissant la diversité des besoins en matière de vitrage tout en se concentrant sur son cœur de compétence. Un autre aspect important de la norme EN 14179-1:2005 est la clarté des exigences supplémentaires applicables au verre trempé, qui est intégré dans des assemblages comme le verre stratifié ou les unités isolantes. Cela offre aux fabricants et aux utilisateurs une meilleure compréhension des caractéristiques que doit avoir le verre dans des contextes plus complexes, sans compromettre ses propriétés mécaniques ou thermiques. Ainsi, la norme non seulement assure une standardisation essentielle pour le verre de sécurité dans la construction, mais elle établit également un cadre pour l'innovation et l'utilisation de verre thermiquement transformé dans des applications variées, tout en maintenant des standards de sécurité rigoureux. Cela la rend particulièrement pertinente dans le contexte actuel des constructions modernes, où la sécurité et la performance du matériau sont des considérations primordiales.
