|Publication Date:||1 October 2008|
|ICS Code (Glass in building):||81.040.20|
This part of ISO 20492 establishes two methods for testing the durability of edge seals of insulating glass units by means of climate tests. The two methods are designated as Approach 1 for markets such as North America and Approach 2 for markets such as Europe.
This part of ISO 20492 is applicable to pre-assembled, permanently sealed, insulating glass units with one or two airspaces, and with capillary tubes that are intentionally left open to equalize pressure inside the unit with the surrounding atmosphere.
This part of ISO 20492 is not applicable to sealed, insulating glass units that contain a spandrel glass coating.
This part of ISO 20492 does not apply to insulating glass (IG) units whose function is decorative only.
