CEN/TC 129/WG 4 - Insulating glass units

This document covers the product standard of insulating glass units (IGU) for use in buildings.
Units for which the intended use is only artistic and therefore no essential characteristics are required, are not subject to CE marking and are not part of this standard.
NOTE   For glass products with electrical wiring or connections for, e.g. alarm or heating purposes, other directives, e.g. Low Voltage Directive, may apply.

This document describes the routine factory production control, the periodic testing and inspection and test methods to verify that an insulating glass unit (IGU) conforms to the system description.

This European Standard describes the test method for the determination of gas leakage rate and specifies the requirements for limit values for gas leakage rate and gas concentration for gas filled insulating glass units made
a)   in accordance with EN 1279 1:2018 and manufactured to EN 1279 6:2018, or
b)   for the purpose to demonstrate that components (e.g. edge seals or spacers) will allow the insulating glass unit to conform to the requirements given in EN 1279 1:2018, Clause 6.

This document (all parts) covers the requirements for insulating glass units. The main intended uses of the insulating glass units are installations in windows, doors, curtain walling, bonded glazing for doors, windows and curtain walling, roofs and partitions.
The achievement of the requirements of this standard indicates that insulating glass units fulfil the needs for intended use and ensures by means of the evaluation of conformity to this standard that, visual, energetic, acoustic, safety parameters do not change significantly over time.
In cases where there is no protection against direct ultraviolet radiation or permanent shear load on the edge seal, as in bonded glazing for doors, windows and curtain walling systems, it is essential to follow additional European Technical Specifications (see EN 15434, EN 13022 1 and prEN 16759).
Insulating glass units that are intended for artistic purposes (e.g. lead glass or fused glass) are excluded from the scope of this standard.
Vacuum insulating glass is not covered by this standard (see ISO DIS 19916 1).
Glass/plastics composites are under the scope as long as the surface of contact with sealants is a glass component.
NOTE   For glass products with electrical wiring or connections for, e.g. alarm or heating purposes, other directives, e.g. Low Voltage Directive, may apply.
This European Standard gives definitions for insulating glass units and covers the rules for the system description, the optical and visual quality and the dimensional tolerances thereof and describes the substitution rules based on an existing system description.

This document specifies the requirements and describes the test methods for edge seal components and inserts. This includes the identification, the determination of physical attributes and the evaluation of characteristics for use in substitution rules in accordance with EN 1279 1:2018.
For the purpose to demonstrate that edge seal components will allow the insulating glass unit to conform to the requirements given in EN 1279 1:2018, Clause 6, EN 1279 2:2018 and EN 1279 3:2018 also apply.

This document describes the test method for the determination of moisture penetration index and specifies the requirements for limit values for insulating glass units made
a)   in accordance with EN 1279 1:2018 and manufactured to EN 1279 6:2018; or
b)   for the purpose to demonstrate that components (e.g. edge seals or spacers) will allow the insulating glass unit to conform to the requirements given in EN 1279 1:2018, Clause 6.

This European Standard specifies requirements, the evaluation of conformity and the factory production control of insulating glass units for use in buildings.
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 ultra-violet radiation at the edges, such as structural sealant glazing systems, additional European technical specifications should be followed (e.g. !EN 15434", !EN 13022-1").
NOTE 3   Units for which the intended use is only ‘artistic’ and therefore no essential requirement is required, are not subject to CE marking and are not part of this European Standard.

CMC - Modification to Foreword (Delete reference to Annex Z, no Annex Z in document)

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.

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.

This draft European Standard is the product standard fo insulating glass units, which defines insulating glass units, and ensures by means of an adequate evaluation of conformity to this standard that: - energy savings are made because the U-value and solar factor do not change significantly; - health because sound reduction and vision do not change significantly; - safety is provided because mechanical resistance does not change significantly.

This Part of this standard, which is inextricably bound up with the other Parts of the standard, covers:
-   the gas leakage rate by testing;
-   the gas concentration tolerances;
as one means of verifying whether a product made in accordance with its system description, conforms with the relevant aspects of the definition of insulating glass units.

This part of the standard covers the evaluation of the edge seal strength, and partial evaluation of moisture and gas permeation through sealants, by testing and/or report examination as a means of verifying whether a product made in accordance with its system description, and its variations in accordance with prEN 1279-1 conforms to the relevant aspects of the definition of insulating glass units.
