The net explosive quantity (NEQ), also known as net explosive content (NEC) or net explosive weight (NEW), of a shipment of munitions, fireworks or similar products is the total mass of the contained explosive substances, without the packaging, casings, bullets etc. [1] It also includes the mass of the TNT-equivalent of all contained energetic substances.
It is a quantitative measure of the level of stimulus required to cause explosive decomposition. The figure of insensitivity is determined from impact testing, typically using a drop-weight tower. In this test, a small sample of the explosive is placed on a small steel anvil which is slotted into a recess in the base of the drop tower.
a. Different explosives of compatibility group A should be packaged separately. b. Explosives of compatibility group L shall only be packed with an identical explosive. c. Explosive articles of the compatibility group C, D, or E may be packed together, and the whole packaged shall be treated as belonging to compatibility group E. d.
Techno-economic assessment or techno-economic analysis (abbreviated TEA) is a method of analyzing the economic performance of an industrial process, product, or service. . The methodology originates from earlier work on combining technical, economic and risk assessments for chemical production processes
The sample is immersed in a hot metal bath, and the time-to-detonation is measured. If over 60 seconds, a fresh sample is run again at a higher temperature. In this manner, it is possible to determine the temperature at which an explosive will detonate on the small scale.
In explosives engineering, sensitivity refers to the degree to which an explosive can be initiated by impact, heat, or friction. [1] Current in-use standard methods of mechanical (impact and friction) sensitivity determination differ by the sample preparation (constant mass or volume is usually used; pile or pressed pellet), sample arrangement (confined/unconfined sample etc), instrument type ...
