This test is used to determine the sensitivity of solid and liquid substances to the effects of intense heat under confined conditions. The apparatus consists of a non re-usable steel tube and re-usable screw cap assembly together with a range of orifice plates with varying vent hole diameters. Because the tube is likely to be destroyed in the test, heating is undertaken in a protected welded box. Heating is provided by propane gas via an industrial cylinder.
