Abstract
A flash fire instrumented manikin articulation system designed to evaluate the thermal protective performance of protective clothing when exposed to flames. The flash fire instrumented manikin articulation system includes an instrumented manikin and an articulation system designed to simulate exposure to a flash fire and simulate dynamic movement including walking and jogging.
