Evaluating Above Ground Depletion in Decking-Type Samples

摘要

A method for determining preservative depletion from above ground decking samples is described along with presentation of preliminary results. The test method uses commercial dimension decking samples with sufficient retain and exposure replication toallow statistical analysis with compensation for both within board and analytical variability in retention data. Data are provided for depletion after 6 and 12 months of exposure for samples treated with CA-C and a two-component organic only system with the variability in analytical results presented both graphically as well as using basic statistics to determine the significance of observed preservative losses.
