FIELD: woodworking industry.
SUBSTANCE: invention relates to a method for evaluation of toxicity sized wood products (plywood and wood chipboards) manufactured using furan resin. Method is accomplished by boiling plywood in ethyl alcohol for 3 h to promote free furfurol contained in plywood to pass into solution, wherein it is them measured by photocolorimeteric technique.
EFFECT: enabled evaluation of plywood toxicity.
