Vacuum stability test

Ditto in 1/8 Al—50% expls and 50% unaffected Sand Test-See Brisance by Sand Test Sensitivity to Impact—See Impact Sensitivity Sensitivity to Initiation—See Initiation, Sensitivity to Stability Test—See Vacuum Stability Test Vacuum Stability Test at 120°—0.37cc of gas evolved in 40 hrs from 1 g sample Velocity of Detonation—See Detonation Rate Viscosity, Efflux-24.8 Saybolt Seconds Method of manuf of HTA—3 is similar to that used for Torpex, namely purified TNT is melted by heating it to ca 100° in a steam-jacketed kettle, equipped with a stirrer. Water wet HMX is added slowly to molten TNT, while continuing to stir it and to heat, until all the water is evapd. Aluminum powder is added and the mixture continued to be stirred until uniform and then cooled, with stirring, to obtain a slurry suitable for pouring into shells or bombs to serve as their bursting charges Refs 1) G.

It is an expl which is as powerful as TNT (99% by ballistic mortar), but more sensitive to impact, being comparable to Tetryl. Its 120° Vacuum Stability Test yields 8cc for a 5g sample in 8 hours, as compared with 6.5cc/5g sample in 15 hours for PETN and 3.8cc/5g sample in 48 hours for Tetryl Refs 1) Beil, not listed in General Index 2) L.F.

Expln temp is above 360°. Impact sensy is 50cm using a BM machine. Hygry test at 90% RH showed gain of 0.88%, and at 100% RH a gain of 1.61% was demonstrated. The International Heat Test at 75° showed a 1.1% loss of wt. Stability testing at 135° for 300 mins showed no acidity or expln.

As judged by vacuum stability test data (see below), Explosive D is of a very high order of stability. The material has been found to withstand storage at ordinary temps for a period of twenty years with no evidence of deterioration, and at 50° for more than five years without marked deterioration... [Pg.754]

According to Rosen Dacons (Ref 39) PA dissolved in trinitrobenzene (5 mole % soln) has an initial gas production of 2.See at NTF/ hour at 210° in a vacuum stability test. For comparison, at nearly identical conditions TNT gives 0.6cc gas/hour at 230°... [Pg.767]

For PETN and similar military explosives a valuable test is a vacuum stability test, in which some of the explosive is heated in vacuum and the rate of evolution of gas measured. [Pg.72]

Absorption test starts with purging process as well as evacuation and then system is thermally stabilized under vacuum. Subsequently, hydrogen at desired absorption pressure is admitted into the system and by observing the pressure decreasing as a function of time, the kinetic curve is registered. [Pg.69]
