R. Meyer J. Köhler A. Homburg Explosives

Bulk Density
the explosive, as well as the gas yield and the heat of explosion. The
higher the loading density of the explosive (molding or pressing density),
the higher its volume specific performance; also, the faster the
reaction rate, the stronger the impact effect of the detonation. Moreover,
an increase in density is accompanied by an increase in the
detonation rate of the explosive, while the shock wave pressure in the
detonation front (W Detonation) varies with the square of the detonation
rate. Thus it is very important to have the loading density as high
as possible.
This is particulary true for W Shaped Charges.
Kast introduced the concept of “brisance value”, which is the product
of loading density, specific energy and detonation rate.
Brisance tests are upsetting tests according to Kast and Heß; the
compression of a copper cylinder is determined by actuating a piston
instrument; alternatively, a free-standing lead cylinder is compressed
by the application of a definite cylindrical load of the explosive being
tested: W Upsetting Tests.
Bulk Density
Schüttdichte; densité apparente
The mass per unit volume of a bulk material such as grain, cement,
coal. Used in connection with packaging, storage or transportation.
Bulk Mix
Sprengstoffmischung für unpatronierte Anwendung; explosif en vrac
A mass of explosive material prepared for use in bulk form without
packaging.
Bulk Mix Delivery Equipment; Misch-Lade-Fahrzeug; véhicule mélangeur-chargeur
Equipment (usually a motor vehicle with or without a mechanical
delivery device) that transports explosives, blasting agents or ingredients
for explosive materials in bulk form for mixing and/or loading
directly into blast holes.
Bulk Strength
Cartridge Strength: Volume Strength
The strength per unit volume of an explosive calculated from its
W Weight Strength and W Density.
