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 ...
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.
Ex: TNT, dynamite, nitroglycerine. 1.2 Explosives with a severe projection hazard. 1.3 Explosives with a fire, blast or projection hazard but not a mass explosion hazard. 1.4 Minor fire or projection hazard (includes ammunition and most consumer fireworks). 1.5 An insensitive substance with a mass explosion hazard (explosion similar to 1.1)
Dynamite is moderately sensitive to shock. Shock resistance tests are usually carried out with a drop-hammer: about 100 mg of explosive is placed on an anvil, upon which a weight of between 0.5 and 10 kg (1 and 22 lb) is dropped from different heights until detonation is achieved. [ 9 ]
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 even if not designed to function by explosion.
On the one hand, what a month. But on the other, what a week. Last Friday, the S&P 500 (^GSPC) and Nasdaq Composite (^IXIC) closed just off record highs, with the former above its 6,100 mark after ...
3 No-Brainer Interest-Rate-Sensitive Dividend Stocks to Buy Right Now for Less Than $1,000. Reuben Gregg Brewer, The Motley Fool. September 23, 2024 at 2:30 AM.
Detonation cord will initiate most commercial high explosives (dynamite, gelignite, sensitised gels, etc.) but will not initiate less sensitive blasting agents like ANFO on its own. 25 to 50 grain/foot (5.3 to 10.6 g/m) detonation cord has approximately the same initiating power as a #8 blasting cap in every 2 to 4 inches (5 to 10 cm) along its ...
