Changes in the loading technique for the Henkin test to be used when investigating high temperatures explosives are reported. Data comparing times-to-explosion for lead, aluminum {open_quotes}foil{close_quotes}, insulated lead, and insulated aluminum {open_quotes}foil{close_quotes} plugs are included. A preliminary temperature-time curve for an HMX sample in the Henkin batch at 272{degrees}C, is reported. The pyrolysis apparatus has been reworked to increase its sensitivity and the results of the changes are readily apparent in the pyrolytic decomposition curves that are reported. Thermal data are reported for some {open_quotes}tailormade{close_quotes} samples of HMX, samples of PETN from different manufacturers, and the six simulated samples of Bridgewater HMX. Differences within these groups are detected by one or another of the tests. Work has begun on a two column gas chromatograph to be used in obtaining chemical reactivity data for use in specifications
