The associations have been working to harmonize the two programs since Fall 2004.
Both programs have developed and implemented a Gas Content Initial and After Weathering (GCIA). The guidelines for certification of triple glazed units and test specimens were standardized between the two programs when IGCC adopted the IGMA Insulating Glass Manufacturing Quality Procedures (TM-4000-02) as the minimum requirement for the program's quality assurance program. The quality procedures requirement will be phased in over approximately the next 18 months.
