Abstract
In DIN EN 622-5 there are two options to test the moisture resistance of bonds in fibreboards, namely the V100-test and the V313-test. Similar options apply also for particleboards. Results of research work conducted on medium density fibreboards reveal that vacuum-pretreatment of the samples prior the V100-test increases the transverse tensile strength. On the contrary, vacuum-pretreatment reduces the transverse tensile strength measured according to the V313-test. The reasons for such a behaviour are discussed.
