|ICS Code (Glass in building):||81.040.20|
This part of ISO 20492 establishes two methods for testing the resistance to fogging of pre-assembled, permanently sealed insulating glass units or insulating glass units with capillary tubes intentionally left open. 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 not applicable to sealed, insulating glass units containing a spandrel glass coating due to testing limitations.
This part of ISO 20492 does not apply to insulating glass (IG) units whose function is decorative only.
