Reaction-to-Fire of Wood Products and Other Building Materials: Part 1, Room/Corner Test Performance

Abstract

This project researched the assessment of reaction-to-fire of common materials using the full-scale room/corner test (ISO 9705) protocol and the predictions of time to flashover using results from the bench-scale cone calorimeter test (ISO 5660-1). Using a burner protocol of 100 kW for 10 min, followed by 300 kW for 10 min and the test materials on the walls only, we obtained effective indications of the fire performance for 11 different untreated wood products, three different fire-retardant-treated (FRT) plywood materials, Type X gypsum wallboard, and FRT polyurethane foam. These same materials were tested in cone calorimeters, both at State Forest Products Research Institute and at Forest Products Laboratory, in which thermophysical properties were derived for use in fire growth models.
