Most of the analytical methods used for determining biocide retentions in treated wood are carried out on a weight/weight basis. These retentions are then converted to a weight/volume basis using average wood specific gravity values. This Standard gives the average values for wood specific gravity, of the wood species or species groupings listed in the AWPA Commodity Standards for use in biocide retention calculations for all applicable AWPA "A" Standards. More accurate retentions can be obtained by using the specific gravity of the untreated wood. When this option is used, the specific gravities should be determined in accordance with ASTM Standard 2395.
