Standard Practice for Accelerated Weathering of Fire-Retardant-Treated Wood for Fire Testing

1.1 This practice covers the durability of a fire-retardant treatment of wood under exposure to accelerated weathering. Four conditioning methods are described. Methods are suitable for application to a test specimen prior to subjecting that specimen to an appropriate fire test. 1.2 This practice is applicable to wood products that have been treated with fire-retardant chemicals by pressure impregnation. 1.3 The test specimens are to be in the
