Scope: This Standard specifies a method for the laboratory evaluation of treated or untreated cellulosic material, cellulosic composite material, or non-cellulosic material for its resistance to subterranean termites. As described below, either a single choice (also referred to as a "no choice") test and/or a two choice test procedure can be used for each material to be tested. Since specific information can be gained from each test, it is recommended that both tests be run. This test method is intended to be a screening test. It may also be used to provide information for standardization of protection treatments. 1.2 The method is applicable to both a single choice (or nochoice) test and a choice test to determine toxicity or acceptance as a food source of cellulosic or cellulosic composite materials to termites.
