Abstract:

A test protocol based on the Intermediate Scale Heat Release Calorimeter (ICAL) was developed to evaluate the potential fire retardant effects of water-based durable agents applied to wood siding. The protocol includes exposure of one meter square specimens of wood siding to one or more constant heat fluxes consistent with those from wildland fires. Specimens both untreated and treated with a fire-retarding gel were evaluated. Time delay to ignition of the treated specimen was the primary measured property, while mass changes prior to and during the fire exposure also were recorded.
