AbstractThere exist Canadian (CAN/CGSB 12.8) and American (ASTM E773 and E774) standards that deal with the edge seal durability of insulating glass units (IGU). Those standards have been in practice for decades, with some modifications made every four to five years when they are due for revision. In recent years, efforts in Canada and USA concentrated on harmonizing the IGU standards to arrive at acceptable test methods for the durability of IGU's and for implementation in IGU certification programs in North America.Accelerated ageing of IG units is a means to test the durability and integrity of the seal(s) of these units by subjecting them to a number of cycles in a controlled environment. The amplitude and frequency of these cycles is determined by consensus among the experts and practitioners in the field. This paper presents a summary of the Canadian, American and the harmonized test methods used in testing the seal integrity and the determination of argon gas of IGU's.
