The use of the Shigometer® and Pilodyn® as non-destructive test methods for detecting decay in CCA treated eucalypt poles
1981 - IRG/WP 2153
The groundline condition of sixty C.C.A. treated eucalypt poles comprising six different species was examined using the Pilodyn® and Shigometer®. Although sensitive to the presence of soft-rot decay, the Shigometer® would seem to offer little practical advantage in the eucalypt soft-rot decay situation, since a comparable visual examination could reveal the presence and extent of decay. Initial...
