Since its establishment in 1989, the company trailblazed the indoor air quality testing market-investing in, developing, and perfecting the most sophisticated dynamic environmental chamber
technology in the world.
Air Quality Sciences, an Atlanta-based, independent laboratory -- the only lab certified for Green Label Plus -- that employs the most up-to-date, dynamic environmental chamber
technology, will perform testing for Green Label Plus.
Inoculated panels were incubated at room temperature in a humid chamber (approximately 100% RH) for either nine days (light growth) or 16 days (heavy growth) before loading into the dynamic environmental chambers
for further evaluation.
2 of the new standard ("Source Control of Indoor Pollutants") specifically references the GREENGUARD Children & Schools Certification Program and the GREENGUARD Environmental Institute's Standard Method for Measuring and Evaluating Chemical Emissions From Building Materials, Finishes and Furnishings Using Dynamic Environmental Chambers
The certification process involves the testing of products in dynamic environmental chambers
for emissions of formaldehyde, volatile organic compounds (VOCs), respirable particles and other pollutants.
