AWPA/WOOD - AWPA A6
STANDARD METHOD FOR THE DETERMINATION OF RETENTION OF OIL-TYPE PRESERVATIVES FROM SMALL SAMPLES
|Publication Date:||1 January 2020|
This assay method is suitable for the determination of creosote, petroleum, and their solutions in treated wood when the sample contains at least 5.0 grams of wood and one gram of oil. Additives, such as copper naphthenate or pentachlorophenol, may not be quantitatively extracted by this method. The method can also be used for the determination of water in treated or untreated wood, but when it is so used, the directions on handling the sample in Standard M2 must be followed carefully.
