چکیده

Equilibrium moisture contents (EMC) of wood species are very necessary in the utilization these service. This study investigated EMC five lesser utilized Ghana and compared it with that three European species. Sixteen randomly sampled specimens each eight (heartwood sapwood) dimensions 3 cm × were exposed at various relative humidity conditions 30%, 45%, 60%, 75% 90% a temperature humidity-controlled climate chamber 25°C accordance to German standard DIN 52182. The Albies alba, Fagus sylvatica Picea abies which Amphimas pterocarpoides, Antiaris toxicaria, Canarium schweinfurthii, Celtis zenkeri Cola gigantea from Ghana. Internal measured datalogger. Samples considered have reached equilibrium any given when daily weight changes less than 0.1 mg according 52183. After last measurements changes, samples dried 103°C until there was constant weight. tropical hardwoods had low sorption values recorded high for this could be attributed differences microstructure woods.
