Abstract : A cooperative study was carried out to determine the equivalency of two alternate methods of exposure testing described in ASTM Standard D 2898-70T, 'Tentative Methods of Test for Durability of Fire-Retardant Treatment of Wood.' Matched specimens of 5/8-inch Douglas-fir plywood, pressure treated with leach-resistant and nonleach-resistant fire-retardant chemical systems, were exposed by methods A and B of the standard and fire tested in the 25-foot and 8-foot tunnel furnaces. Method A is the 12-week 'rain test' exposure in use at Underwriters' Laboratories, Inc., and method B is the 1,000-hour accelerated weathering chamber apparatus in use at the Forest Products Laboratory. Results are discussed. (Author Modified Abstract)
