A lot of 50 eucalypt poles presenting external deterioration by fungus was taken from service and tested. These poles were classified into five degrees of sanity according to evaluation criteria adopted by the IPT Wood Division. After being classified, they were tested with respect to their bending resistance, in order to gather information about their critical degree of sanity which may define the pole substitution while in service. With the results obtained, it was possible, according to Brazilian standards, to conclude that poles presenting a degree of sanity of 1 and 2 must be replaced whereas those with a degree of sanity of 3, 4 and 5, after proper maintenance, can remain in service.
