Announces Acceptance of GasGlass for IGMA Certification Program
The Insulating Glass Manufacturers Alliance (IGMA) has announced that the GasGlass®
instrument manufactured by Sparklike of Helsinki, Finland, will be accepted as
a viable method for determining initial gas fill concentration for the IGMA Certification
Program, effective immediately.
IGMA conducted the first data correlation study between gas fill measurements
taken by the gas chromatograph method and the GasGlass device in 2002. The results
of this study indicated that measurements taken with the GasGlass device were
comparable to those taken with a gas chromatograph. Based on this research encompassing
200 gas-filled insulating glass units, the IGMA GasGlass Best Practices Working
Group was formed in January 2003 to expand the initial correlation data. The working
group developed standardized operating protocol for the device, which forms the
foundation for the development of an ASTM standard (currently under development),
developed a second round robin series of testing to establish correlation between
different GasGlass devices and is presently working on a position paper for the
Margaret Webb, IGMA executive director stated, "This device provides another
methodology for approved certification testing laboratories to verify initial
gas fill and is truly a non-destructive verification process unlike the gas chromatograph
or the oxygen analyzer. This will remove the requirement for manufacturers to
use septum plugs so that the units tested for initial gas fill can undergo cycling
without compromising the insulating glass unit seal."
Webb also noted, that "IGMA is continuously researching new methods that
will offer alternatives not just to certification but also to the insulating glass
manufacturing process itself."
