Positive dosage response of CCA in hardwood power poles to soft rot indicated from New South Wales soft rot survey dat

Experience and observation have shown that retentions of less than 16 kg/m³ in the sapwood of individual hardwood poles are unlikely to delay its deterioration sufficiently to ensure an economic performance in some instances. The higher retentions of current practice should do so subject to adequate inspection and maintenance. Increases in retentions requirements up to 35 kg/m³ more or less, depending on species should now be implemented in the interest of securing a greater margin of confidence in the product at small additional cost.
