Title: Accelerated weathering of fire-retardant-treated wood for fire testing

Author: White, Robert H.;

Date: 2009

Publication Series: Miscellaneous Publication

Description: Fire-retardant-treated products for exterior applications must be subjected to actual or accelerated weathering prior to fire testing. For fire-retardant-treated wood, the two accelerated weathering methods have been Method A and B of ASTM D 2898. The rain test is Method A of ASTM D 2898. Method B includes exposures to ultraviolet (UV) sunlamps in addition to water sprays. D 2898 was recently revised to include Methods C and D. Method C is the “amended rain test” described in the acceptance criteria for classified wood roof systems (AC107) of the ICC Evaluation Service, Inc. Method D is the alternative rain test described in ASTM E 108 for roof coverings. Issues with the current methods are the limited availability of the UV sunlamps specified in the standard and the large amount of water used that may require special disposal.
