ABSTRACT:
A method and apparatus for measuring the decomposition of a gaseous mater under controlled temperature and time conditions. The method is particularly useful for testing the decomposition of pyrotechnic compositions useful in grenades. The method vaporizes the test composition in an enclosed vaporization chamber. Thereafter the process flows a stream of an inert gas into the enclosed vaporization chamber and mixes the vaporized composition with the stream of an inert gas to form a mixed stream. The mixed stream is transferred to an enclosed temperature exposure chamber and exposed to regulated heating conditions for a determined time with subsequent analysis of the exposed mixed stream.
