Abstract
The long-term behaviour of 13 industrial particleboards of emission class 1 was examined. Their low formaldehyde emission potential was reached by several methods. Only 4 of these 13 board types showed a creep factor which was considered to be sufficient. A correlation between formaldehyde release and creep behaviour could not be assessed. Therefore, the short-term properties did not allow secure statements regarding the expected creep behaviour of a particleboard. For this purpose, a storage in alternating climate with and without loading is necessary whereas for preliminary examinations the largescale bending tests can be neglected. Based on the determined regression line it was possible to indicate maximum reduction factors which must be respected if a certain creep factor considered to be critical should not be exceeded.
