the method of coating deposition, e.g. chemical-vapour deposition, sputtering, etc.
the materials making up the layer(s) of the coating,
the order of stacking of the layers,
the glass substrates,
the classification of the coated glass. NOTE The product description can include an identity card (see EN 1096-1:2012, Annex A). The layers may be listed either in full, i.e. chemical composition, or by a manufacturer's code. Product families shall be defined in terms of the above product description taking into account the criteria for demonstrating equivalence of coatings (see EN 1096-2:2012, Annex F and EN 1096-3:2012, Annex B).

FprEN 1096-4:2015 (E) 5 Foreword This document (FprEN 1096-4:2015) 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 Unique Acceptance Procedure. This document will supersede EN 1096-4:2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. The main changes compared to the previous edition are the following: a) The standard has been revised to fulfil the requirements of the Regulation (EU) No 305/2011 (Construction Product Regulation), modified by Regulations (EU) No 157/2014, (EU) No 568/2014 and (EU) No 574/2014; b) The tolerance on emissivity is reduced to +0,01 for coated glass with a declared normal emissivity lower than 0,10; c) The solar factor, g, is listed within the spectrophotometric characteristics to be declared in the Declaration of Performances (DoP); d) The durability/conformity assessment is listed within the characteristics to be declared in the DoP; e) The mechanical resistance shall be given in the DoP by the characteristic bending strength of the glass substrate. EN 1096, Glass in building - Coated glass, consists of the following parts: — Part 1: Glass in building – Coated glass - Part 1: Definitions and classification — Part 2: Glass in building - Coated glass - Part 2: Requirements and test methods for class A, B and S coatings — Part 3: Glass in building - Coated glass - Part 3: Requirements and test methods for class C and D coatings — Part 4: Glass in building - Coated glass - Part 4: Evaluation of conformity/Product standard — Part 5: Glass in building – coated glass – Part 5: Test method and classification for the Self-cleaning performances of coated glass surfaces This document contains other aspects of importance for trade. Note: Due to fact that the EC has not yet been able to confirm the financial commitment for the New Approach Consultants’ work in 2015, there are currently no New Approach Consultants in place for 2015. Therefore the provisions of CEN-CENELEC Guide 15 cannot be met. This shall not prevent the processing of draft standards nor the offering of harmonized standards to the European Commission. In particular, draft standards can be sent to vote without Consultant assessment. This note will be removed from the Foreword of the finalized publication. kSIST FprEN 1096-4:2015

This description shall describe the product and/or product family. Disclosure of the product description shall be at the discretion of the coated glass manufacturer or his agent except in the case of regulatory requirements. The product description shall contain at least the following: • a reference to EN 1096-1, EN 1096-2, EN 1096-3, EN 1096-4 and when relevant FprEN 1096-5:2015, and all other standards with which the manufacturer claims compliance, • the type of coating, i.e. online, off-line, • the method of coating deposition, e.g. chemical-vapour deposition, sputtering, etc. • the materials making up the layer(s) of the coating, • the order of stacking of the layers, • the glass substrates, • the classification of the coated glass. NOTE The product description may include an identity card (see EN 1096-1:2012, Annex A). kSIST FprEN 1096-4:2015
FprEN 1096-4:2015 (E) 9 The layers may be listed either in fullf i.e. chemical compositionf or by a manufactureras code. Product families shall be defined in terms of the above product description taking into account the criteria for demonstrating equivalence of coatings (see EN 1096-2:2012, Annex F and EN 1096-3:2012, Annex B). The substitution of materials and/or components shall maintain the conformity with the product description. The substituting materials and/or components can be added to the product family and also the product description when compliance has been demonstrated. 4.2 Determination of the characteristic’s performances 4.2.1 Characteristic of coated glass 4.2.1.1 General The characteristics of coated glass, listed in Table 1, are in general those of the glass substrate and can be found in the appropriate product standard (see 4.2.1.2). Since they are not changed significantly by the coating process, they shall be used for coated glass. For glass substrates covered by European specifications, generally accepted values, declared values, or calculated values of the characteristics listed in Table 1 shall be used. If glass panes are used which are not covered by harmonized European Specifications (as defined in regulation EU305/2011), 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. Certain coated glasses can be toughened or heat strengthened. These final products should comply with the appropriate product standard and the performance of the coated glass should be determined on the final product in accordance with EN 1096–2:2012, Annex A or EN 1096–3:2012, Annex A.

The information supplied with the incoming glass may be used for the characteristics listed in 4.2.2.3 to 4.2.2.11, as the coating process does not alter the values. 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. NOTE EN 15998 specifies the testing methodology to 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. 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. 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. 4.2.2.6 Safety in use - Explosion resistance: impact behaviour and resistance to impact Explosion resistance shall be determined and classified in accordance with EN 13541. 4.2.2.7 Safety in use - Burglar resistance: shatter properties and resistance to attack Burglar resistance shall be determined and classified in accordance with EN 356. 4.2.2.8 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. 4.2.2.9 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 value is given in the standards for the appropriate glass substrate (see 4.2.1.2) 4.2.2.10 Safety in use - Mechanical resistance: Resistance against wind, snow, permanent load and/or imposed loads of the glass unit The mechanical resistance is a characteristic value. The value to be declared is the characteristic bending strength, as defined in the standards for the appropriate glass substrate.
