Rapid IGU Quality Assessment from IGCC

The Insulating Glass Certification Council, sponsor of the IGCC/IGMA certification program, is currently testing a pilot program that would enable IG manufacturers to provisionally certify their products in just four weeks. The existing full certification takes an average of 24 weeks.

Provisional certification would enable the manufacturer to sell a certified product pending the outcome of full ASTM tests. The Provisional Certification Program was designed to assess the ability of a manufacturer to take an established type and arrangement of sealant(s) and components, and assemble them to a specified standard. The program was evaluated by a correlation study last year.

This study compared the program’s pass/fail data to identical units that were evaluated to IGCC’s existing certification results with surprising precision. The program utilizes the test methods outlined in ASTM E-2190 for the stability of the gas fill, and the unit’s durability when subjected to high humidity and accelerated weathering environments. Evaluation is made after a shorter exposure time but with more stringent pass/fail criteria, along with additional quality assurance requirements developed by IGCC.
