Report on a Study to Utilize the ICAL Apparatus for the Determination of the211 Effectiveness of Fire Resistant Durable Agents

摘要

A test protocol based on the Intermediate Scale Heat Release Calorimeter (ICAL)211u001ewas developed to evaluate the potential fire retardant effects of water-based 211u001edurable agents applied to wood siding. The protocol includes exposure of one 211u001emeter square specimens of wood siding to one or more constant heat fluxes 211u001econsistent with those from wildland fires. Specimens both untreated and treated 211u001ewith a fire-retarding gel were evaluated. Time delay to ignition of the treated 211u001especimen was the primary measured property, while mass changes prior to and 211u001eduring the fire exposure were also recorded.
