Abstract
Na dimenzijsko stabilnost plošč vpliva več dejavnikov, med njimi tudi uporabljena vrsta lesa, faktor zgostitve in gostota plošč. V laboratorijskih pogojih smo izdelali tri različne vrste ivernih plošč. Za izdelavo plošč smo uporabili iveri smreke, bukve in kombinacijo obeh. Preskušance smo ciklično izpostavili nizki (33 %) in visoki (85 %) relativni zračni vlažnosti. Spremljali smo spremembe mase, dolžine in debeline. Najmanjše vrednosti pri spremembi mase in debeline smo ugotovili pri ploščah, kjer smo uporabili iverje smreke in bukev s faktorjem zgostitve 1,46. Pri spremembi dolžine smo najmanjše vrednosti ugotovili pri ploščah iz bukovega iverja.

Title:The influence of wood species on dimensional stability of particle boards
Abstract:
The dimensional stability of a panel is influenced by several factors, including the type of wood, the condensation factor and the density of the panel. In laboratory conditions we created three types of chipboards. To make the panels we used the chips of spruce, beech and a combination of both. The test subjects were cyclically exposed to low (33 %) or high (85 %) relative humidity. We monitored the changes in mass, length and thickness. The minimal value of change in mass and thickness was observed in panels which were made of spruce and beech with a density factor of 1.46. The minimal value of change in length was observed in panels made of beech.

Keywords:particle boards, sorption, dimensional stability, spruce (Picea abies Karst.), beech (Fagus sylvatica L.)
