This description shall describe the product and/or product families. Disclosure of the product description shall be at the discretion of the thermally toughened glass manufacturer or his agent except in the case of regulatory requirements. The description shall contain at least a normative part. The description may also contain an informative part, when the manufacturer foresees further development of the product. The normative part of the description shall contain the following minimum information: - a reference to EN 13024 parts 1 and 2 and all other standards with which the manufacturer claims compliance. - the radiometric properties and durability of coated glass, i.e. coated glass that conforms with EN 1096-1, EN 1096-2, EN 1096-3, when those properties are changed, intentionally or unintentionally, by the thermal toughening process.

4.3.1 Characteristics of thermally toughened borosilicate safety glass 4.3.1.1 General The characteristics of thermally toughened borosilicate safety glass are in general those of the glass substrate ( see 4.3.1.2). 4.3.1.2 Characteristics of the borosilicate glass panes used for the production of thermally toughened borosilicate safety glass Panes shall be made of borosilicate glass according to EN 1748-1-1. The panes may be coated according to EN 1096 –1, EN 1096-2, EN 1096-3 and/or enamelled according to EN 13024-1. For the characteristics listed in Table 1, for the borosilicate glass panes, generally accepted values or calculated values may be used.
Since the majority of the characteristics of Table 1 are not changed significantly by the thermal toughening process they shall be used for thermally toughened borosilicate safety glass. The exceptions shall be the characteristic bending strength (fg,k) and the resistance against sudden temperature changes and temperature differentials.

If some coatings, i.e. coated glass conforming with the EN 1096 series, when thermally toughened, change their radiometric properties the manufacturer shall refer to the following for the determination of the appropriate characteristics, etc.:  4.3.2.11 for the emissivity;  4.3.2.12 for the light transmittance and reflectance;  4.3.2.13 for the solar energy transmittance;  EN 1096-2 for the durability of A, B and S coatings;  EN 1096-3 for the durability of C and D coatings. 4.3.2 Determination of characteristics of thermally toughened borosilicate safety glass products
If the thermally toughened glass manufacturer wishes to claim that any performance characteristic is independent of the production equipment used then the factory production control system shall be in accordance with this standard including his specific process control conditions. 4.3.2.1 Safety in the case of fire - Resistance to fire Fire resistance shall be determined and classified in accordance with EN 13501-2.

4.3.2.6 Safety in use - Burglar resistance: shatter properties and resistance to attack Burglar resistance shall be determined and classified in accordance with EN 356. 4.3.2.7 Safety in use - Pendulum body impact resistance: shatter properties (safe breakability) and resistance to impact Pendulum body impact resistance shall be determined and classified in accordance with EN 12600. 4.3.2.8 Safety in use - Mechanical resistance: Resistance against sudden temperature changes and temperature differentials The resistance against sudden temperature changes and temperature differentials is a generally accepted value that is given in EN 13024-1 and shall be ensured by compliance with this standard. 4.3.2.9 Safety in use - Mechanical resistance: Resistance against wind, snow, permanent load and/or imposed loads of the glass unit The mechanical resistance of thermally toughened borosilicate safety glass is a characteristic value that is given in EN 13024-1 and shall be ensured by compliance with this standard. As long as on the concerned construction or building site no part of prEN 13474 is applicable then the current method of determining mechanical resistance in the country of destination shall be applied.
The manufactured or supplied thickness of thermally toughened borosilicate safety glass shall conform to the ordered thickness.

The manufacturer shall supply specific installation instructions or make reference to appropriate technical specifications. Note 1: The durability of glass products depends on:
 building and construction movements due to various actions;  building and construction vibrations due to various actions;  deflection and racking of the glass support due to various actions;

This shall include the following:
a) Inspection of samples taken at the factory in accordance with a prescribed test plan;
b) Initial inspection of the factory and of factory production control;
c) Continuous surveillance and assessment of the factory production control. 2) Initial type testing of the product; Note: There may be a need to involve a third party, with 1b, 1c, and/or 2, for the purpose of regulatory marking (see Annex ZA). 5.2 Initial type testing of the product (see 5.1, 2) 5.2.1 General All the product’s characteristics shall be initial type tested to verify they are in conformity with the requirements of this document. In addition instead of performing any actual testing, initial type testing may make use of: – generally accepted and/or conventional and/or standardised values, in the Clause 2 referenced standards, or in publications that are referred to in these standards; – standardised calculation methods and recognised calculation methods in the Clause 2 referenced standards, or in publications that are referred to in these standards;

1 The terms ‘manufacturer’ and ‘producer’ are understood as being synonyms (see CPD working document NB-CPD/02/019-issued 24 April 2002 – page1)

initial type testing shall consist of: a) mechanical strength measurement in accordance with EN 13024-1; b) fragmentation test in accordance with EN 13024-1 5.2.2.2 Test specimens The test specimens needed for the initial type test shall be processed from float glass according to EN 13024-1 in accordance with this document.
The ‘simplest’ type of edge work specified in the manufacturers production control documentation shall be used. However, if an arrissed edge is used then all other types of edge working are deemed to satisfy. The number of test specimens is as follows: a) For mechanical strength measurement they are given in Table 2a for float glass, Table 2b for coated float glass and Table 2c for enamelled float glass. b) For fragmentation 5 test specimens per thickness are required.

Product thickness range
Number of test specimens for the mechanical strength measurement
– minimum ≥ 2 – first after minimum ≥ 2 – center of range ≥ 2 – last before maximum ≥ 2 – maximum ≥ 2
TOTAL ≥ 10 NOTE : When the production range consists of: - two thicknesses, the distribution shall be as equal as possible -a single thickness, all specimens are of the same thickness

Fully enamelled Minimum
≥ 10
Note 1: This table covers all enamelled designs and all produced thicknesses Note 2: Mechanical test shall be undertaken with enamelled surface in tension Note: Strength measurement outcomes are expressed in force per unit of area and are therefore independent of the thickness. Hence strength measurements may be performed on a collection of test specimens with different thicknesses. 5.2.2.3 Test results a) When the mechanical strength is measured, no measured value shall be below that given in Clause 9 of EN 13024-1. However, if one value falls below then the manufacturer shall ensure that the results relate to a 5 % probability of breakage at the lower limit of the 95 % confidence interval.
b) In the fragmentation test, no test specimen shall exhibit a fragmentation assessment that does not meet Clause 8.4 of EN 13024-1 5.2.2.4 Measurement of surface pre-stress The manufacturer may also use surface pre-stress measurement as a means of product control. If this is done then all test specimens shall be measured prior to testing. This will show the relationship between surface pre-stress and mechanical strength/fragmentation. Manufacturers with more than one production line may perform the initial type test on specimens from one line. The outcome value of surface pre-stress measurement may then be used as reference for the other production lines and shall be confirmed by factory production control (FPC). This may also be applied to new production lines. 5.2.2.5 Thermally toughened patterned glass Initial type testing of thermally toughened patterned glass may not be undertaken as a result of the wide variety of patterned surfaces of patterned glass in accordance with EN 13204-1. Compliance of thermally toughened patterned glass shall be ensured by the sampling during product control given Annex A – Table A.1 – 3.1.3 together with either 3.1.4.2 or 3.1.4.3. 5.2.3 Initial type testing of characteristic’s performances
All characteristics in 4.3.2 shall be subject to initial type tests in accordance with Clause 5.2.1. Optimising thermal toughening settings specifically for one characteristic may affect negatively the optimised settings for a different characteristic. When performance of both characteristics will be declared, the affected characteristic shall be subject to a further type test.

All elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures. This production control system documentation shall ensure a common understanding of quality assurance and enable the achievement of the required product characteristics and the effective operation of the production control system to be checked. Factory production control shall be according to Annex A of this document. Note 1: A factory production control system to EN ISO 9001 made product specific to this standard shall also be deemed to satisfy the requirements of this clause. Note 2: There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA). Annex A of this document also summarizes the tests that shall be carried out by the manufacturer as part of the production control in the factory, and as further testing of samples taken at the factory in accordance with a prescribed test plan. If the factory production control includes the optical pre-stress measurement for control purposes, the method shall be correlated. Therefore, prior to any initial type test on mechanical strength/fragmentation according to 5.2.2.1, all test specimens shall be measured to determine their optical pre-stress. Outcomes shall be used as reference values during factory production control. 5.4 Initial inspection of factory and of factory production control (see 5.1, 1c) The initial inspection of the factory and of the factory production control shall cover the parameters listed in Table 3 in conjunction with Annex A.
Note: There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA).
