Thermal properties and chemical reactivity. January--March, 1971

Two coupon test samples containing LX-09/Sylgard/Mulberry and LX-10/Sylgard/Mulberry were disassembled for evaluation. Thermal analysis data for the explosives and the analysis of the atmosphere are reported. Identification of several components in the atmosphere was made. The problems associated with the analysis of LX-09 for FEFO by gas chromatography are discussed and the data from the analysis of two specially prepared samples of LX-09 are reported. The data for a series of standard and modified Henkin time-to-explosion for PETN are reported. The modified time-to-explosion runs are first cooled for a fixed time, preheated for 40 to 80 seconds, recooled for a fixed time and then reheated until the sample explodes. A 0.42 cc liquid sample was trapped during the pump out of the W-68 AAU and a preliminary analysis of the sample is reported. The analysis of the atmosphere in the first samples from the PASS A LX-09 evaluation program is reported
