[Formaldehyde emissions from wooden products and office furniture]. / Emisja formaldehydu z meblarskich tworzyw drzewnych i z mebli biurowych.

The formaldehyde emission from wood-products (particleboards, particleboards veneered with artificial veneer, laminated particleboard, hard fibreboards, plywood) and office furniture was measured with the use of environmental chamber (0.2 m3, 0.6 m3, 1.0 m3 capacity) in the following conditions: temperature 23 degrees C, relative humidity 45%, 1 air exchange/hour and factor loading 1 m2/m3. Formaldehyde was determined by using colorimetric methods. Among the tested products, hard fibreboards, plywood and almost all of the enriched particleboards should not contaminate indoor air with formaldehyde over its threshold limit values. The tested office furniture fulfill of the hygienic requirements.
