O presente trabalho teve por objetivo caracterizar um lote de madeira de eucalipto comercializada por uma empresa do setor florestal brasileiro. Utilizou-se, neste trabalho, a madeira de Eucalyptus, provavelmente E. grandis W. Hill ex Maiden., adquirida no mercado local e no estado de secada ao ar. Todo o lote foi dividido em dois sublotes, um de madeira mais pesada e outro da mais leve, porque se percebeu, no recebimento do carregamento, que havia nele tábuas com diferenças notáveis de peso. Os corpos-de-prova foram preparados a partir de tábuas retiradas ao acaso de cada um desses dois sublotes. Fez-se, portanto, a caracterização dessa madeira para possíveis comparações dos valores de suas propriedades físicas e mecânicas, segundo a norma NBR 7190 (1997). Feitos os testes, de fato pôde-se verificar a existência de duas populações de tábuas com propriedades mecânicas significativamente diferentes. The objective of the present work was to characterize a lot of Eucalyptus wood marketed by a Brazilian forest company. In this work, Eucalyptus wood, probably E. grandis W. Hill ex Maiden, was purchased in the local market in the air-dry condition. The whole lot was subdivided in two sub-lots; one with heavier wood, the other with lighter. The reason for this was that the shipment arrived with boards having notable differences in weight. Test-specimens were prepared from boards taken from each sub-lot. The characterization was therefore carried out in twice as many test-specimens as required by Brazilian standards, as described in the NBR 7190 (1997) standard. The tests showed the existence of two board populations with significantly different mechanical properties
