This test method covers the laboratory evaluation of treated or untreated cellulosic material for its resistance to subterranean termites. This test should be considered as a screening test for treated material and further evaluation by field methods is required. Different kinds of equipment and materials to be used in the evaluation of the cellulosic material include containers, glass or clean plastic, tray, enamel, stainless steel, paper towels, and volatile chemicals. Southern yellow pine (SYP) sapwood with no visible defects and smoothed surfaces shall be evaluated by using reagents like benzalkonium chloride solution and distilled water. Other wood species may be used, but in each separate test using other species as the major test wood, five SYP sapwood blocks should be used as additional controls to permit the correlation of test results among laboratories. A block evaluation with corresponding rating system shall be performed by visualization method.
