Sensitiveness of expls

C) Dunkle s Syllabus (1960-1961), p 13a (Stein found the rifle-bullet sensitivity of expls to increase with increasing thickness of confinement. For equivalent thickness, the expls were more bullet-sensitive in steel than in A1 bombs. As a quantitative test of deton of the expl, measurements by means of piezoelectric shock-velocity gages showed promise. When there was no firm indication... [Pg.153]

Accdg to Baum et al (Ref 8, pp 56-66), the following factors, besides chemical structure, are influencing sensitivity of expls... [Pg.213]

The sensitivity of expls is a characteristic of great importance and can be correlated with the rate of deton. Perfect crysts and other nearly perfect elastic materials are the most sensitive, while liquids or colloids (plastic, fluid or hard) resist initiation and also have tendency to damp out-the wave of deton. The sensitivities of endothermic and exothermic compds are different and this causes them... [Pg.228]

Any form of mechanical action (such as impact, friction, etc) can cause a deton if the expl is sensitive to this action. Earlier discussions of the mechanical sensitivity of expls made use of an assumed special ability of expls to deton under mechanical stimulus alone. Recent work, particularly the experiments of Bowden et al [Refs 13,... [Pg.402]

In order to understand more thoroughly the phenomenon of sensitivity of expls, Mabek (Ref 13, p 43) considers a hypothetical case of an explosive in which the chemical reaction is originally started by an external energy source and is allowed to grow in violence until the extreme regime of detonation is attained. Then the process of build-up can be divided into four stages of development... [Pg.512]

Glass in Priming Compositions. It is known that sensitivity of expl mi its to friction (percussion) is greatly increased when a small amt of ground glass [or of other abrasive material, such as sand or carborundum (See Vol 2, p C65-L)] is mixed with (he expl... [Pg.720]

Iowa (Ref 28) reported static electricity developed during LA handling. Monte si (Ref 31) described a fixed gap electrostatic discharge apparatus for characterizing expls.

The third method of decreasing the sensitivity of expls is by the addition of an energy absorber. One of the most efficient energy absorbers is wax or a waxy substance. They are the most widely used non-expl material used to desensitize expls... [Pg.329]

Berta Apparatus is a device used in Italy for detn of impact sensitivity of expls. The test, known as Saggio alia Berta is mentioned in Vol l,p XVII of this Encyclopedia under Impact Sensitivity Test. The values obtained by Berta app are similar to those obtained by the USBurMines app, with 2kg wt. Avogadro(Ref) gives the following Berta values, in cm PETN 38, PA 60 and TNT 80... [Pg.104]

As will be shown in the next section, in many exptl determinations of shock sensitivity the input shock travels thru an inert medium (barrier) before it enters the test sample. In some of the early studies of shock sensitivity of expls, shocks were characterized by their propagation velocity U in the inert barrier (Ref 2). As will be shown... [Pg.287]

Bartels (Ref 39) has described a gap-test which he claims is applicable to measuring the shock sensitivity of expls as well as potentially explodable pyrot compns. This test differs from the NOL SSGT (Fig 4) in that confinement of the acceptor is much reduced and w is used as the inert barrier. Instead of a witness plate Bartels used an A1 witness-rod ... [Pg.295]
