The seasoning of forest products is undertaken for a wide range of end uses and is becoming increasingly required for applications and building construction and secondary manufacturing industries. A wide range of applications of new technology and specifically required seasoning schedules is being actively developed for such requirements, but less attention has been given to the means by which wood can be prepared for successful preservation treatments by seasoning or more general conditioning treatments. Much of the knowledge of the practical means of achieving good treatments through prior seasoning and conditioning resides in the skill and experience of larger treating companies. Although many of the pertinent means of achieving proper pretreatment seasoning are mentioned in important sets of standards, such as those of the American Wood Preservers Association (AWPA) and the Canadian Standards Association (CSA), it is often necessary for the consumer of treated forest products to develop the appropriate means of seasoning for his special case through reliance on the knowledge of the treater. In the case of a large consumer, such as the major utilities, there is often his own body of experience gained through the activities of a research and development group.
