Susan Test Cyclotol

Cyclotol 75/25 (RDX/TNT 75/25) has both good and bad properties as measured by the Susan test (Fig 3). The threshold velocity for reaction is probably about 180ft/sec (55m/sec), which is rather typical of the TNT-bonded cast expls and higher than most plastic-bonded expls.

As acceptors used in underwater tests were 50/50-Pentolite, TNT, 60/40-Cyclotol, PBX 9404-03 and LX-04-1. The results gave thresholds for burning which are comparable in magnitude to Susan and Skid tests, but lower than those obtd by the modified gap test. This showed that burning can be produced at lower shock levels if the pressure were held longer and the wave front made flatter...
