ABSTRACT
The purpose of this paper is to determine beech and oak (sessile oak and oak) pulpwood mass loss as a result of its drying on a storage period of three months and to establish a measurement methodology of its moisture content. During the storage period wood mass decreased by 16...26.48% in beech and by 9.81...18.42% in oak species. The measurement methodology of wood moisture content involves the following aspects: (i) choosing the method of moisture content determination (with the electric humidometer or by drying in the oven); (ii) size and setting up of a batch of sample logs and (iii) extraction place for wood slices. As far as the first aspect is concerned the method recommended for determining stacked wood moisture content is the one by drying in the oven. The batch size was determined statistically according to the variation coefficient of the number of logs from the stack and according to the stack surface. A number of 19 logs for beech and of 22 logs for oak species is usually sufficient for determining wood moisture content in stacks with a surface ranging between 10 and 30 m2. With regard to the wood sample extraction place, research has demonstrated that the moisture content measured in the section situated 10 cm away from the ends of logs is representative for the moisture content of the entire log.
