English title: Durability as indication of wood qualityAbstract
The article reviews the change in how the most sufficient wood material was chosen for different uses. The craftsmen used different characteristics to determine the quality of wood, for instance, tree species, location in the stem, whether it was sapwood or heartwood etc. Scientifically, the quality of the wood has been described by, for instance, specific gravity, bending strength and compressive strength. Durability would, however, be better attribute than strength to describe the quality of wood, because circumstances, like humidity and temperature can change where the wood is used. The article discusses further the development of durability indexes.
