Glass in buildings — Insulating glass — Part 3: Gas concentration and gas leakage
ISO 20492-3:2010 specifies two methods of test for insulating glass units, including a determination of the gas leakage rate and a determination of gas concentration tolerances. The two methods designated as approach 1, which is intended for use in markets such as North America, and approach 2, which is intended for use in markets such as Europe.
Glass in buildings - Insulating glass — Part 2: Chemical fogging tests
ISO 20492:2008 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.
ISO 20492:2008 is not applicable to sealed, insulating glass units…
Glass in buildings - Insulating glass — Part 1: Durability of edge seals by climate tests
ISO 20492-1:2008 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.
ISO 20492-1:2008 is applicable to pre-assembled, permanently sealed, insulating glass units with one or two airspaces, and with capillary…
