The field performance of CCA-C treated sawn refractory softwoods from North America
1997 - IRG/WP 97-40085
…sawn refractory softwoods. As a result, the existing North American wood preservation standards for sawn refractory softwoods appear not to be based upon field performance data, but are believed to be based upon the depth of incisions which were achievable by conventional incisors. In the mid 1980's, new…
