The ISO/TC 160/SC 1-WG4 Insulating Glass convened for the first time in 1995 and the publication of the standard represents years of dedicated effort by the industry. Special thanks are extended to the task group convener (since 1997); Bill Lingnell, Lingnell Consulting Services and IGMA’s Technical Consultant and Jeff Haberer, Cardinal IG who acted as the secretary for the group. These two individuals were instrumental in navigating the ISO process, meeting all the deadlines and working closely with the ISO editor.
The standard comprises 4 parts:
20492-1 Glass in buildings --Insulating glass-- Part 1: Durability of edge seals by climate tests
20492-2 Glass in buildings --Insulating glass-- Part 2: Chemical fogging tests
20492-3 Glass in buildings --Insulating glass-- Part 3: Gas concentration and gas leakage
20492-4 Glass in buildings --Insulating glass-- Part 4: Methods of test for physical attributes of edge seals.
This standard combines the IG test methods and specifications of ASTM (E2188, E2189, and E2190) and EN 1279 parts 2, 3, 4, and sections of Part 6.
Established on October 2, 2000, IGMA has been representing the North American industry for the past ten years though the organization’s roots date back to 1967 when the Insulating Glass Manufacturers Association of Canada (IGMAC) and the Sealed Insulating Glass Manufacturers Association (SIGMA) were both incorporated. IGMA is acknowledged internationally as the leading technical organization for insulating glass.
