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. 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. 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.
