Determination of formaldehyde emission from different types of wood based panels using different standard test methods. studying the effect of board coating and thickness on the formaldehyde emission as well as the effect of different types of formaldehyde based resins. Evaluation of inter laboratory comparison of formaldehyde release from particleboard. Determination of the relationships between different methods and estimation the relationships between some of formaldehyde values determined in the present work and the international standard limitation using the conversion factor equations, which have been developed by the literature.
