Durable wood product evaluations
Snapshot: In an effort to reduce the amount of time required to obtain meaningful durability data for wood products, it has become widely accepted to use smaller specimens in field tests. Smaller specimens generally yield faster results but tests comparing small specimens with matched larger lumber specimens showed that the relationship of the failure rates in the matched samples varies greatly. This research shows that more testing is needed before we can be confident that results from accelerated methods reflect the durability of commercial wood products.
