Upgraded software and new technology from Georgia-Pacific Chemicals enable composite wood manufacturers to address today's stringent formaldehyde testing requirements with even more confidence.
The new patent-pending technology for the GP Dynamic Microchamber (DMC) has been shown to improve accuracy to within ±.005 ppm (when testing in a range of .01 to .2 ppm). As a result, accuracy is enhanced for testing panels for California Air Resource Board (CARB) phase 2 requirements, as well as testing for the more stringent Ultra Low Emitting Formaldehyde (ULEF) Reduced or Exempt standards.
Created by GP Chemicals more than 20 years ago, the GP DMC is a computer-integrated, small scale formaldehyde test system capable of providing emissions results of 11 samples in 3 ½ hours – more than twice the capability compared to using the ASTM D6007-02 small scale chamber test methodology. It is also capable of performing an equilibrium test.
The GP DMC is one of the few alternative small scale test methods approved by CARB for conducting quality control testing of formaldehyde emissions, and it is a method accepted by the Composite Panel Association.
The primary alternative test method used by particleboard and medium density fiberboard (MDF) mills in North America, the GP DMC is also used successfully in Europe and South America.
GP Chemicals not only created the patent-protected equipment, but also provides annual calibrations, upgrades, repair service, training and parts. An updated manual has also been produced to accompany the new copyrighted software and provide users key technical information on optimal use of the GP DMC. The manual, software upgrade and other services are available through www.gp-dmc.com
