“-”-””22. Hiqh Order Detonation -Refer to detonation.
,--
23.~ -(1) Ordnance that is not loaded with explosive. Maybe similar in appearance to explosively
loaded ordnance. May be filled with some non-explosive filler to simulate the weight and trajecto~
characteristics of the explosive loaded version.
(2) Inert material (used in UXO as non-energetic filler, referred to as inert filler) shows no
exothermic decomposition when tested by DSC or DTA. Moreover, the inert material shall not
show any incompatibility with energetic material with which it may be combined when tested by
recognized compatibility tests. Inert material shall neither alter the onset of exotherm of the DSC
or DTA trace of the energetic material, increase the rate of decomposition or gas evolution of the
energetic material.
24. Initiator - Blasting cap or other initiator type, such as an exploding bridge wire, designed to initiate
the detonation in the main-charge explosive. Maybe referred to as a detonator or “cap”.
25.insensitive Hiah Explosives - Explosive substances that, although mass detonating, are so insensitive
that their is negligible probability of accidental initiation or transition from burning to detonation.
26. Linear-ShaPed Charqe - A shaped charge designed to cut straight lines.
27.l@ - UXO that is loaded with explosive or is suspected to contain explosive.
28. Low Enercw EED - All EEDs except slapper detonators and those initiated by exploding bridgewire
(EBW).
29. Low Explosive -An explosive which deflagrates or burns rather than detonates; that is, the rate of
advance of the reaction zone into the unreacted material is less than the velocity of sound in the
unreacted material. An explosive may react as a low explosive or as a high explosive depending on how
it is initiated and confined. For example, a double based propellant when initiated in the usual manner
is a low explosive, but can be made to detonate if it is initiated by an intense shock. Conversely, a high
explosive like TNT, under certain conditions, can be ignited by flame and will burn without detonating.
Low explosives include propellants, certain primer mixtures, black powder, photoflash powders, and
delay compositions,
30. Low Order Detonation - A chemical reaction in a detonatable material in which the reaction front
advances with a velocity which is appreciably lower than that which is the characteristic detonation
velocity for the material in question. In a low order detonation, the ordnance case usually breaks into
several large fragments rather than many small ones.
31. Misfire - The failure of a charge to explode in response to a proper initiation attempt. When the
charge fires at some time later than intended, a misfire may be referred to as a hangfire.
,-32.Mock Explosive - Substance bearing similar physical properties (texture, density, cohesion, etc.) To
m explosive material. They are undetonable, however some are exothermic materials and will burn.
They are used to represent explosive for purposes such as dry run testing of equipment. DOE mock
