initial type testing determination of the performance of a product (characteristic, durability), on the basis of either actual tests or other procedures (such as conventional, standardised, tabulated or general accepted values, standardised or recognised calculation methods, test reports when made available, …), in accordance with this European Standard that demonstrates compliance with this European Standard 3.2
test report document that covers the results of tests undertaken on a representative sample of the product from production
or on a prototype design of the product 3.3 product description document that details the relevant parameters, e.g. process conditions, structure, etc., for defining a product that complies with the standard. It includes specific reference(s) to characteristics that are modified by the production process 3.4 significant change variation in performance beyond the permitted tolerance for the characteristic 4 Requirements 4.1 Product description For conformity purposes the heat soaked thermally toughened glass manufacturer is responsible for the preparation and maintenance of the product description. This description shall describe the product and/or product families. Disclosure of the product description shall be at the discretion of the heat soaked 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:

EN 1096-1, EN 1096-2, EN 1096-3, when those properties are changed, intentionally or unintentionally, by the thermal toughening and heat soaking process. The definition of product families shall be consistent with the normative part of the product description. The substitution of materials shall maintain the conformity with the product description. The substituting material can be added to the product family and also the product description when compliance has been demonstrated. 4.2 Conformity with the definition of heat soaked thermally toughened soda lime silicate safety glass Products shall conform to the definition and fulfil the requirements of heat soaked thermally toughened soda lime silicate safety glass as defined in prEN 14179-1. 4.3 Determination of the characteristic’s performances 4.3.1 Characteristics of heat soaked thermally toughened soda lime silicate safety glass 4.3.1.1 General The characteristics of heat soaked thermally toughened soda lime silicate safety glass are in general those of the glass substrate (see 4.3.1.2). 4.3.1.2 Characteristics of the soda lime silicate glass panes used for the production of heat soaked thermally toughened soda lime silicate safety glass Panes shall be made of soda lime silicate glass according to EN 572-1, EN 572-2, EN 572-4, EN 572-5. The panes can be coated according to EN 1096-1, EN 1096-2, EN 1096-3 and/or enamelled according to prEN 14179-1. For the characteristics listed in Table 1, for the soda lime silicate glass panes, generally accepted values or calculated values shall 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 heat soaked thermally toughened soda lime silicate safety glass. The exceptions being 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 heat soaked thermally toughened change their radiometric properties the manufacturer shall refer to the following for the determination of the appropriate characteristics, etc.:  4.3.2.12 for the emissivity;  4.3.2.13 for the light transmittance and reflectance;  4.3.2.14 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 heat soaked thermally toughened soda lime silicate safety glass products 4.3.2.1 General If the heat soaked 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 European Standard including his specific process control conditions.

EN 673 with:  emissivity ε : the declared value of the glass manufacturer. If the information is not available, the emissivity shall be determined in accordance with EN 12898;  nominal thickness of the glass panes. However, the information supplied about the thermal properties of the incoming glass can be used if the thermal toughening and heat soaking process does not alter the values. 4.3.2.13 Energy conservation and heat retention - Radiation properties: Light transmittance and reflectance The light transmittance and reflectance shall be determined in accordance with EN 410. However, the information supplied about the radiation properties of the incoming glass can be used if the thermal toughening and heat soaking process does not alter the values. 4.3.2.14 Energy conservation and heat retention - Radiation properties: Solar energy characteristics The solar energy transmittance and reflectance shall be determined in accordance with EN 410. However, the information supplied about the radiation properties of the incoming glass can be used if the thermal toughening and heat soaking process does not alter the values. 4.4 Durability When products conform to the definition of heat soaked thermally toughened soda lime silicate glass as in 4.2, then the characteristics’ performances in 4.3.2 are ensured during an economically reasonable working life. The durability of glass products, including their characteristics, is ensured by the following:  compliance with this standard;  compliance with instructions from the glass product manufacturer or supplier.
1 prEN 13474 series is currently being prepared.

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

EN 572-1 and EN 572-2 in accordance with this European Standard. 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 are 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.

NOTE 1 This table covers all enamelled designs and all produced thicknesses. NOTE 2 Mechanical test 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 then no measured value shall be below that given in 11.4 of prEN 14179-1:2001. 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 10 of prEN 14179-1:2001.
