Abstract

Samples of preservative-treated aspen waferboard exposed outdoors for 30 months were compared using pin penetrations of the 6-Joule Pilodyn. These results correlated well with rankings of treatment performance based on more laborious standard mechanical tests, and demonstrate the potential for use of the Pilodyn as a tool to evaluate wood composites in test exposures with minimal destruction.
