In what follows we will describe some impact machines and impact tests, ie the apparatus and methods for measuring impact sensitivity. We will then present and discuss impact sensitivity data for common explosives obtained with these machines by different laboratories. Then we will briefly consider how impact sensitivity tests have contributed to the development of the theory of initiation of explosives. Finally, we will examine impact testing from a theoretical point of view... [Pg.300]

The vacuum stability test and heat test are the most common tests used to determine the compatibility and stability of explosives with polymers or contact materials. However, an impact sensitivity test is sometimes used in order to derive additional information. [Pg.177]

The temperature and humidity of the laboratory (temperature -26-27 °C and humidity -60-65%) where impact sensitivity test is done, should be maintained. [Pg.192]

Drop Test. See Impact Sensitivity Test Effect of Pressure on Performance in Detonators. See Pressure Effect, etc Explosion(or Ignition) Temperature. When O.02g charges of pentryi were dropped on molten Wood s metal preheated to various temps, no expin or ignition took place at 233°(5 trials), but at 235° the sample ignited in 3 secs after it touched the hot surface. The same time interval was observed at 240°, while at 250° it was 2 secs, at 260° 1.5 to 2 secs and at 270—280° 1.5 secs (Ref 4,p 1389)... [Pg.427]

Expls that do not freeze when exposed to temps as low as 35°F(+ 1.67°) are called LF(low-freezing), those not freezing at 0s F(—17.78°) are ELF(extra low-freezing) and those not freezing at lower temps are NF(qod-freezing).

J. Eadie reported in Ref 71 that the shock sensitivity of HMX/wax compacts is found to decrease as the amount of the HMX surface coated with wax increased. This thus indicates that the shock sensitivity depends on the surface area of the reactive expl exposed to reaction products. Similar results were observed 20 years earlier and reported in Ref 26. The following is a quote from this Ref, It was noted in the course of this work that the quantity of inert material per se was not the important factor in the phenomenon of desensitization. As a matter of fact, it was the thoroughness with which the explosive crystals (PETN) were coated that appeared to be an important factor in desensitization. Table 6 contains the results of the impact sensitivity tests conducted on PETN-wax mixts where both the quantity of wax in the mix and the degree of coating on the expl crystal are taken into account...
