Fire Resistant Wood Products

A new ASTM test method will help determine the effects of high temperatures and humidity on fire-retardant-treated wood products. This test method (soon be published as D7857, Test Method for Evaluating the Flexural Properties of Fire-Resistant Structural Composite Panels Exposed to Elevated Temperatures) will help product development labs with first steps in developing new products for wood-construction markets.

Specifically, according to ASTM member Jerry Winandy, "this new standard will provide an accelerated test of structural composite panels at elevated temperatures and controlled humidity. This could eventually be used for wall and roof sheaths." Winandy, an adjunct professor of wood science at the University of Minnesota, notes that the test method could help producers of engineered wood composites when developing additives to protect from fire or to enhance durability.

This test method can provide critical preliminary data when estimating the durability of materials subjected to elevated in-service temperatures as high as 77 degrees Celsius (170 F).
