IGMA Continues Harmonization with ISO Standard for Insulating Glass
September 29, 2010
The Insulating Glass Manufacturers Alliance (IGMA) announced the publication of ISO 20492, Parts 1, 2, 3 and 4 for insulating glass units. The ISO/TC 160/SC 1-WG4 Insulating Glass convened for the first time in 1995 and, according to IGMA, the standard’s publication represents years of dedicated effort by the industry.
In its announcement, IGMA extends special to the task group convener 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,” IGMA notes.
The standard is comprised of four 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; and
- 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.
