AWPA E16-16 Standard Field Test for Evaluation of Wood Preservatives to be used Above Ground (UC3B); Horizontal Lap-Joint Test
: Brown Technical Book Store
This Standard specifies a method for field testing experimental or commercial wood preservatives intended for use in wood to be exposed to the weather out of contact with the ground without the additional protection of a surface coating (i.e. Use Category 3B). The main objective of the method is to evaluate the relative effectiveness of the preservative, applied to jointed samples of pine sapwood by a treatment method relevant to its intended practical use. Effectiveness is evaluated relative to a reference preservative treatment. The method may also be modified to test naturally durable wood or wood composites. This test method is intended to provide information for standardization of protection treatments. It may also be useful as a screening test.
