Rifle bullet impact test

Molex no s 2 3 are physical mixts of AN 52—84, K perchlorate 0—20, DNT oil 7—12, baked cork 1—10, A1 powd 5—7 Ca carbonate 1%. They exhibited satisfactory sensitivity to impact, friction, flame initiation, and had excellent stability. Philips (Ref 4) reported on tests of Molex B and BB , manufd by the National Explosives Co. They are described as physical mixts of AN 80.77—85.06, flake A1 6.02—6.10, DNT oil 4.32—5.84, activated cork 2.55—4.47, Ca stearate 1.10—1.99 and Ca carbonate 0.83-0.95%. They were shown to be stable, to have fairly high brisance, but to be sufficiently sensitive to expl in the rifle bullet impact test. Byers (Refs 1 3) describes blasting expls similar in compn...

Ml 35-L), contains RDX 5 to 15, AN 25 to 35, TNT 40 and A1 20%. When cast, DBX has a d of 1.68g/cc and is gray in color. It is less sensitive than Torpex, as shown by its impact test value of 10", fewer expins in the rifle bullet impact test, and a greater minimum detonating charge of Diazodinitrophenol whether in loose or cast form. Cast DBX has a rate of detonation of 680Qm/sec as compared with 7600 for Torpex,... 

Although the friction pendulum test shows no measurable difference in sensitivity between Tritonal and TNT, impact tests indicate Tritonal to be somewhat more sensitive to impact than TNT and less so than Tetryl. The rifle bullet impact test value for Tritonal is more similar to that of Tetryl than that of TNT. The expln temp test value of Tritonal (470°) is almost identical with that of TNT...
