Contribution to investigation of humidity influence when testing particleboard properties

Humidity's influence at the moment of testing the most important particleboard properties has not been sufficiently researched. It was believed that this influence had no practical significance. In this work, based on conducted research on only one particular type of particleboards, the obtained results show that humidity's influence at the moment of testing on the thickness swelling and bending strength of particleboards should not be neglected.
