Two preliminary experiments were conducted to determine (1) how the time-to-explosion (TE) using Lee Plugs (short stainless steel and aluminum) would compare with the TE obtained using the lead plugs; and (2) how the Lee Plugs would perform with du Pont's EL-511 and Tacot at 314[degrees]C and 362[degrees]C., respectively. The Pantex-built chromatograph is operating as a two-column instrument, and the findings of an extensive check out of the instrument are reported. The chemical reactivity test sample holders were shown to evolve approximately 30[mu]l of N[sub 2]+ O[sub 2] and 3[mu]l of CO[sub 2] when heated for 22 hours. A number of thermal tests were made on two lots of LX-04-1 (39A and 38B) to determine if any differences could be detected that would explain why Lot 38B tensile strength is much better than 39A when both were made from the same lot of Viton A. Some differences were detected, but they have not been related to the tensile strength of the material. The time-to-explosion for various Adiprenes with HMX are reported, and they indicate that there could be some reactivity between the Adiprene and HMX. Pantex and LASL DTA thermograms and pyrolograms for PETN and Extex are reported for comparison to determine how the sensitivity of Pantex instruments compare with LASL, and if these instruments could be used to qualify PETN and Extex in accordance with LASL Specification 13Y-104481.

Available in PDF, EPUB and Kindle. Book excerpt: 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°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.

Available in PDF, EPUB and Kindle. Book excerpt: Henkin's test data are reported for comparisons of the following: dry-to-moist samples, PBX 9404 in brass and gold-plated blasting caps, Holston HMX with Bridgewater HMX, LX-04-1 and LX-04-1 + Ucon oil, and PETN, LX-04-1 and Extex. The time-to-explosion curves for HMX and PBX 9404 are also given. A description of the pyrolysis apparatus and the method of calibrating the sample temperature to the response of the thermal conductivity detector are reported. The pyrolytic decomposition curves of several standard explosives and six specially prepared HMX samples (LRL raw material No. A-311 through A-316) are included. A controlled atmosphere D.T.A. is described and the thermograms of PETN with an atmosphere of air at 85 psi, nitrogen at 85 psi and 200 psi are given. The thermograms indicate that PETN becomes more sensitive as the pressure increases. Chemical reactivity data are reported for Comp B, Comp B-3, Comp C-4, HMX, PBX 9011, PBX 9205, Tetryl and TNT. Also, test results are reported for LX-01-1 and Comp B-3 heated at 150°C for 22 hours, LX-02-1 heated at 100°C for 22 hours, and pressed pellets of PBX 9404 and PBX 9404 + powdered lead.
