In the case of initiating expls, the requirements are the same as in (4) except that a hot flame is not required, but rather that it produce a shock wave strong enough to detonate a HE such as Tetryl, PETN, RDX, PA, TNT, etc... [Pg.653]

Metallic K. in admixtures with Ag or Hg oxides or chlorides, or in contact with chlf or carbon tetrachloride, can be expld by strong impact (Ref 3). Such mixts were proposed by Staudinger (Ref 1) for use as initiating expls for blasting or in bursting projectiles... [Pg.836]

If the relation lef/lr (where lt is the width of the reaction Zone) of an initiating expl is small, the process starting with a low detonation velocity eventually developed into normal detonation with velocity D This is represented by curve 2 of Fig 2... [Pg.200]

Some initiating expls (such as MF, DADNPh, TATNB, etc) stop detonating from thermal impulse but can be ignited. This phenomenon, known as dead-pressing , was... [Pg.215]

The destructive stress of initiating expls may be applied to any expl material, but will be transmitted only to a limited extent in materials which do not release energy in sufficient quantity or intensity to maintain it... [Pg.227]

For initiating expls only 0.01 g samples are prescribed. When the metal in the crucible reaches the desired temp, place the shatterproof-glass barricade in front of the apparatus, and lower (by means of a lever) the clamp to a point corresponding to the fixed depth of immersion of the cap in the molten metal.

The smallest influence of confinement is for initiating expls and for brisant expls of high density and large diameter of chge... [Pg.653]

The influence is the lowest for initiating expls, such as MF or LA. For brisant expls the influence of confinement is noticeable only at small diams and low densities of charges... [Pg.658]

The reaction zone length "a (See Fig 1) is the important parameter when considering boostering of main explosive charges. It largely determines how easily and how rapidly stable deton may be established in the main chge. The shorter the reaction zone length, the more rapidly and the more easily stable conditions are reached in the initiated expl. [Pg.677]

Igniters, which include devices called squibs, lighters and firing devices, etc are used for initiating expl or pyrotechnic compns whose nature is such that it is desirable to use flame or flash for their initiation and not a shock as produced by primers or detonators. [Pg.733]

The design shown in Fig 72 proved to be unsuitable for initiating expls less sensitive than RDX because they require higher voltages than can be achieved by the device shown. Such insensitive HE s are TNT and Ammonium Picrate. Modifications shown in Figs 73 and 74 proved to be more or less suitable for such expls... [Pg.808]

Sensitivity to Initiation by Primary Explosives, Detonators and Boosters. It can be expressed as the minumum weight of an initiating expl or the No of detonators to cause a complete detonation of a HE (high expl). See Voll,... [Pg.311]

A sample (35g) of explosive (or propellant) is placed in the center of a sheet of combustible paper and one of its comers is ignited. Then observe the behavior of ex pi (or proplnt) when die flame reaches it. Sume substances bum slowly, others rapidly, while primary or initiating expls detonate Ref H. Ficheroulle A.
