| Abstract: | Abstract An apparatus, hereinafter named the modified vacuum thermal stability (MVTS) test apparatus, that replaces the mercury manometric method used to determine the vacuum thermal stability of energetic materials is described. The volume calibrated MVTS system provides continuous pressure/time data for the duration of the test via a computerized data acquisition system. Total gas volume (reduced to STP) is computed from the pressure data. Subsequent gas chromatographic analysis of the evolved gaseous mixture further provides identification and individual volumes of the components. Water/solvent volume is obtained by difference (Vp — VCalibrated Gases GC). |
