Since they are not changed significantly by the assembly process, they shall be used for the insulating glass unit. For panes made of glass covered by European specifications, generally accepted values, declared values, or calculated values of the characteristics listed in Table 1 shall be used. SIST EN 1279-5:2018

EN 1279-5:2018 (E) 10 If glass panes are used which are not covered by harmonized European Specifications (as defined in regulation EU 305/2011), it shall be demonstrated that those glasses have a chemical composition and a mechanical stability over time equivalent to the requirements of the relevant standard listed.

In the case of variable radiation properties (e.g. electrochromic glass, integrated blinds or screens, etc), maximum and minimum values shall be given. 4.2.2.2 Safety in the case of fire - Resistance to fire Fire resistance shall be determined and classified in accordance with EN 13501-2. The testing methodology specified in EN 15998 shall be used for glass products that are claiming fire resistance. 4.2.2.3 Safety in the case of fire - Reaction to fire Reaction to fire shall be determined and classified in accordance with EN 13501-1. For classification, consideration shall be given to: a) The following product changes require new type testing on reaction to fire: 1) reduction of the reaction to fire classification of the glass components in the insulating glass unit; SIST EN 1279-5:2018

EN 1279-5:2018 (E) 11 2) reduction of the reaction to fire performance of the organic sealant in the edge seal. The reaction to fire performance shall be evaluated by the measurement of the PCS, see EN ISO 1716 [1]. b) However, when not tested, the insulating glass unit shall be classified either by: 1) the reaction to fire classification of the glass component used in the insulating glass unit, or 2) the classification of an insulating glass unit using the same organic sealant in the edge seal. The classification claimed shall be the lower of the two possibilities. 4.2.2.4 Safety in the case of fire - External fire performance (for roof coverings only) Where the manufacturer wishes to declare external fire performance (e.g. when subject to regulatory requirements), the product shall be tested and classified in accordance with EN 13501-5. For classification, consideration shall be given to: a) The following product changes require new type testing on external fire performance: — reduction of external fire performance of the glass component in the insulating glass unit. b) However when not tested, the insulating glass unit shall be classified: — by the external fire performance of the glass components used in the insulating glass unit. The classification claimed shall be that of the glass component with least performance. NOTE A test performed with clear float glass is regarded representative for tinted, patterned, coated, surface treated and thermally treated substrates. 4.2.2.5 Safety in use - Bullet resistance: shatter properties and resistance to attack Bullet resistance shall be determined and classified in accordance with EN 1063. a) In those instances when the bullet resistance property of the insulating glass unit is ensured by one component only, there is no need for testing provided that the conditions 1 and 2, or 1 and 3 are fulfilled: 1) The bullet resistant component is correctly oriented, and 2) When the bullet resistant component is classified “NS”, the additional glass component(s) are placed in front of the bullet resistant component, on the attack side, or 3) When the bullet resistant component is classified “S”, the additional glass component(s) may be placed either on the attack side or on the protected side. NOTE 1 In that situation, the width of the gas space(s) and the nature of the gas have no influence on the result. The classification of the insulating glass unit shall be the same as for the glass component used. If the identification of the product is clear enough to avoid confusion, the performance of each component can be declared, in the order given by the composition. NOTE 2 It is common practice to give the composition starting from the outer IGU component. SIST EN 1279-5:2018

EN 1279-5:2018 (E) 12 b) In those instances when the bullet resistance property of the insulating glass unit is achieved only by the complete unit, this IGU shall be tested and classified in accordance with EN 1063. When adding a glass component to this insulating glass unit, there is no need for further testing provided that conditions 1 and 2, or 1 and 3 are fulfilled: 1) The insulating glass unit is correctly oriented, and 2) When the bullet resistant insulating glass unit is classified “NS”, the additional glass component(s) is not placed on the protected side and the gas space width is not reduced. In the case of additional component(s) being placed in the cavity, i.e. when a double insulating glass unit is transformed into a triple insulating glass unit, the sum of the width of the two gas spaces of the triple insulating glass unit is not less than the one of the tested double insulating glass unit, or 3) When the bullet resistant component is classified “S” it may be placed either on the attack side, on the protected side, or between the components of the insulating glass unit. NOTE 3 The nature of the gas has no influence on the result. 4.2.2.6 Safety in use - Explosion resistance: shatter properties and resistance to impact Explosion resistance shall be determined and classified in accordance with EN 13541. a) In those instances when the explosion resistant property of the insulating glass unit is ensured by one component only, there is no need for testing provided that each of the following conditions is fulfilled: — The explosion resistant component is correctly oriented; — The additional glass component(s) are placed in front of the explosion resistant component, on the attack side. NOTE 1 In that situation the width of the gas space(s) and the nature of the gas have no influence on the result. The classification of the insulating glass unit shall be the same as for the glass component used. If the identification of the product is clear enough to avoid confusio
