Quantity-Distance (QD) is the foundation of DOD explosives safety standards. It defines levels of protection from blast based on relationships between the quantity of explosive material (NEW) and distance. The relationships are based on levels of risk considered acceptable for specific exposures but they do not provide absolute safety or ...
Class 1: Explosives. Division 1.1: Explosive that has a mass explosion hazard. A mass explosion is a detonation of almost entire load instantaneously. Division 1.2: Goods and Substances without a mass explosion hazard, but with a projection (shrapnel/fragmentation). Division 1.3: Goods and substances with a mass fire hazard, and a minor, blast ...
HAZMAT Class 1 Explosives. US Army trucks laden with ammunition, displaying a Class 1.1D Explosives placard on the front. Hazmat Class 1 are explosive materials which are any substance or article, including a device, which is designed to function by explosion or which, by chemical reaction within itself is able to function in a similar manner ...
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.
An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be chemical energy, such as nitroglycerin or grain dust
A shaped charge is an explosive charge shaped to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the ...
The different physical forms and fabrication methods are grouped together in several use forms of explosives. Explosives are sometimes used in their pure forms, but most common applications transform or modify them. These use forms are commonly categorized as: [1] Pressings. Castings. Polymer bonded. Putties (a.k.a. plastic explosives) Rubberized.
Contents. Table of explosive detonation velocities. This is a compilation of published detonation velocities for various high explosive compounds. Detonation velocity is the speed with which the detonation shock wave travels through the explosive. It is a key, directly measurable indicator of explosive performance, but depends on density which ...
