This document (EN 1279-1: 2004) has been prepared by Technical Committee CEN /TC 129, "Glass in building", the secretariat of which is held by IBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2004, and conflicting national standards shall be withdrawn at the latest by December 2004.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 Z, which is an integral part of this document. This European Standard “Glass in Building - Insulating glass units” consists of the following Parts – Part 1: Generalities, dimensional tolerances and rules for the system description. – Part 2: Long term test method and requirements for moisture penetration. – Part 3: Long term test method and requirements for gas leakage rate and for gas concentration tolerances. – Part 4: Methods of test for the physical attributes of edge seals. – Part 5: Evaluation of Conformity. – Part 6: Factory production control and periodic tests. The annexes A and B are normative, and annex C is informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

1 Scope This European Standard is the product standard for insulating glass units, which defines insulating glass units, and ensures by means of the evaluation of conformity to this standard that over time: – energy savings are made because the U-value and solar factor do not change significantly; – health is preserved because sound reduction and vision do not change significantly; – safety is provided because mechanical resistance does not change significantly. It covers characteristics that are of importance for trade. Marking conditions are included. NOTE 1: For glass products with electrical wiring or connections for, e.g. alarm or heating purposes, other directives, e.g. Low Voltage Directive, may apply.
The main intended uses of the insulating glass units are installations in windows, doors, curtain walling, roofs and partitions where there exists protection against direct ultraviolet radiation at the edges. NOTE 2: In cases where there is no protection against direct ultraviolet radiation at the edges, such as structural sealant glazing systems, additional European technical specifications should be followed. Units that are intended for artistic purposes are excluded from this standard. This Part of this European standard, which is inextricably bound up with the other Parts of the standard, covers the materials, the rules for the system description, the optical and visual quality and the dimensional tolerances for insulating glass units. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated by amendment or revision. For undated references, the latest edition of the publication referred to applies. EN 572 Glass in Building - Basic soda lime silicate glass products -

NOTE: systems are available where the spacer and hermetic seal are included within a single edge sealing system. SIST EN 1279-1:2004

EN 1279-6;  the recommendations of clause 4.4 and Annex B of prEN 1279-5 being followed;  and in the case of gas-filled insulating glass units, the requirement of the gas leakage rate according to EN 1279-3 being satisfied Seal properties, validation methods and requirements are summarised in table 1 and table 2. Substitution of materials and of components shall maintain the conformity of the system with the definition of insulating glass units. The relevant seal properties and the related derived requirements are summarised in annex B, tables B1 and B2, together with the validation methods. When meeting the requirements, the substituting materials and components shall be added to the system description. Changes within components shall also comply with the above requirements. The requirements for the changes in the quantity of desiccant are given in annex B, table B3. When meeting the requirements, the change within the component shall be added to the system description. If glass panes are used which are not covered by European specifications, it shall be demonstrated that those glasses have a chemical and mechanical stability over time comparable with:  soda lime silicate glass according to EN 572-1,  or borosilicate glass according to EN 1748-1-1,  or glass ceramics according to EN 1748-2-1,  or alkaline earth silicate glass according to prEN 14178-1 Table 1 — Seal performance, validation method and requirements for IGUs
