Evaluation of the Relationship between Formaldehyde Emissions from Particleboard Mobile Home Decking and Hardwood Plywood Wall Paneling in Experimental Mobile Homes

摘要

HUD and several building supply associations cooperatively designed and implemented a program of testing and research to evaluate the impact of formaldehyde concentrations of when reduced formaldehyde-emitting hardwood plywood paneling and particleboard decking is used in mobile homes. The relationship between the formaldehyde levels produced in the mobile homes and formaldehyde-emission potential was evaluated by monitoring the mobile homes weekly for formaldehyde levels and by carefully testing the wood products using desiccator and chamber test methods. Testing the emission potential of formaldehyde in the wood products using the desiccator and chamber methods showed clear and major differences between the emission potential of the two difference in emissions from the particleboard. The proposed Hardwood Manufacturers Association and National Particleboard Association product guidelines are inadequate in meeting target levels of .4 to .5 ppm of formladehyde.
