  • Device and method for frictionally testing materials for ignitability
    Patent number: 4561784
    Abstract: Test apparatus for determining ignition characteristics of various metal in oxidizer environments simulating operating conditions for materials, the test apparatus has a chamber (6) through which the oxidizing agent flows, and means for mounting a stationary test sample (36) therein, a powered, rotating shaft (E) in the chamber rigidly mounts a second test sample (35). The shaft is axially movable to bring the samples into frictional engagement and heated to the ignition point. Instrumentation 16, 32, 48, 49, 50, 51, 52, 53, 54 connected to the apparatus provides for observation of temperatures, pressures, loads on and speeds of the rotating shaft, and torques whereby components of stressed oxygen systems can be selected which will avoid accidental fires under working conditions.
