Moisture content of composition is below 1.8% (in excess of 100%). Toy torpedoes containing more than 5 grains of an explosive composition. Paper caps containing more than .35 grain of explosive composition. Semtex became notoriously popular with terrorists because it was, until recently, extremely difficult to detect,2 as in the case of Pan Am Flight 103. Composition B, colloquially "Comp B", is an explosive consisting of castable mixtures of RDX and TNT. Black powder is the name given to the earliest known chemical explosive. Detonating Cord – a flexible cord containing a center core of high explosives used to detonate other explosives. It was also used for the explosive lenses in the first implosion-type nuclear weapons developed by the United States. Incoming high explosive anti-tank rounds pierce the outer steel plate, then detonate the plastic explosive. Based on the composition, it is divided into two : Pure explosive ingredient; Mixed detonator; 2. Firecrackers or salutes exceeding 5 inches in length or 3/4 inch in diameter. It is still referred to by this name in France and also by some Americans. For its original military use it was manufactured under the name B 1. Black powder, for composition c-4, type ii sara title iii information: waste disposal method: store and handle waste explosives as class a explosives. They are generally not used for ordinary blasting as they tend to be significantly more expensive than other materials that perform just as well in this application.

It remained a service item through the Korean War, but had marginal plasticity at the very low temperatures encountered in Korean winters, and was significantly toxic, including by vapour and skin absorption. Composition C-3 was very similar to Composition C-1, but removed the solvent and varied the exact proportions of plasticisers to improve high temperature storage. The original material was developed by the British during World War II, and was used in the Gammon bomb. Explosive Materials Disposal Department of the Treasury Bureau of Alcohol, Tobacco and Firearms. There are three classes of C4, with varying amounts of RDX and polyisobutylene. It was standardised as Composition C when introduced to US service. 1-1697 2/1/2006 Military Munitions and Explosives of Concern: A Handbook for Federal Land Managers, with Emphasis on Unexploded Ordnance BLM Handbook [H-1703-2] FWS Handbook 2006 Bureau of Land Management U.S. Casting is performed under vacuum when reduction of voids is a concern.

Reactive armor in tanks uses plastic explosives sandwiched between two plates of steel. It comes in the form of white There are three fundamental types: mechanical, nuclear, and chemical. An explosive perfectly capable of producing an explosion may liberate its energy without producing one. [citation needed], One of the simplest plastic explosives was Nobel's Explosive No. [5] The language of the patents indicate that at this time, Silberrad saw no need to explain to "those versed in the art" either what he meant by plasticity or why it may be advantageous, as he only explains why his plastic explosive is superior to others of that type. Research on a replacement for C-2 was begun prior to 1950, but the new material, new generation of Composition C (number four, C-4), did not begin pilot production until 1956. The velocity of detonation is about 7600 m/s (25,000 feet per second. [8]:8–109 C3 was effective but proved to be too brittle in cold weather and was replaced with C4. Consequently, it was replaced around 1944 by Composition C-4. Composition C-3 was very similar to Composition C-1, but removed the solvent and varied the exact proportions of plasticisers to improve high temperature storage. It suffered from a relatively limited range of serviceable temperatures, and was replaced by Composition C-2 around 1943. Composition C2 had a wider temperature range at which it remained plastic, from −30 to 52 degrees C. Composition C2 was replaced by Composition C3, which was a … Add 20ml of ammonium hydroxide (Ammonia water 10%) Filter. In the first embodiment of invention, industrial explosive composition comprises hexogen with particle size less than 0.7 mm, liquid petroleum product with kinematic viscosity below 2400 mm 2 /s as measured at 20°C and/or coal powder, and dense granulated ammonium nitrate and/or porous granulated ammonium nitrate. Class 2 - Explosive Composition A-5 which has passed the. It is so successful that it remains in army service up to the current time without any significant changes. This material consisted of 88.3% RDX and a mineral oil-based plasticiser and phlegmatiser. 808, also known as Nobel 808 (often just called Explosive 808 in the British Armed Forces during the Second World War), developed by the British company Nobel Chemicals Ltd well before World War II.

An insensitive melt-cast explosive composition incorporating on the one hand a meltable part formed of at least one meltable explosive and, on the other hand, a solid part incorporating oxynitrotriazole (ONTA) and cyclonite (RDX). An explosive composition comprising 81% to 98% by weight of an explosive agent, 1% to 15% by weight of a solid fuel and 0.5% to 2% by weight of a polymeric adherent wherein the explosive agent, solid fuel and polymeric adherent are dispersed throughout the composition. The composition of black powder or gunpowder is not set. Variants have different proportions and plasticisers and include composition C-2, composition C-3, and composition C-4.[1]. The origin of the obsolete term "plastique" dates back to the Nobel 808 explosive introduced to the U.S. by the British in 1940. It is understood that the compositions of these two explosives are as follows: RDX Composition C RDX Composition C2 Cyclonite, % 88.3 78.7 Plasticizer, % 11.7 - MNT, % - 2.70 DNT (oil), % 12.0 TNT, % 5.0 Wet nitrocellulose, pyroxylin, % 0.3 Wet' nitrocellulose, pyro, % 0.3 Special solvent, % 1.0 OBJECT: 2. 6 cap (one-inch diameter drill hole) over a range of 2-30% by weight nitro-aliphatic hydrocarbon relative to the weight of the dry component at a 50:50 volume ratio of the nitro-aliphatic hydrocarbon to the … One of the first reported and tested compositions of C-3 was very similar to earlier Composition C-2 and contained 77% RDX, 3% tetryl, 4% TNT, 1% NC, 5% NT, and 10% DNT. Its a plastic explosive containing RDX and an inert plasticizer. It is a yellow, putty-like material. A common commercial use of plastic explosives is for shock hardening high manganese percentage steel,[2] a material typically used for train rail components and earth digging implements. MOD explosives: PE2 (sheet explosive, superseded by SX2). Here are the explosive chemicals examples in daily life: An early use of plastic explosives was in the warhead of the Petard demolition mortar of the British Armoured Vehicle Royal Engineers (AVRE); said mortar was used to destroy concrete fortifications encountered during Operation Overlord (D-Day). The last two compounds (they are very poor explosives) are oily liquids and plasticise the mixture. The Composition C family is a family of related US-specified plastic explosives consisting primarily of RDX. liquid DNT and small amount of NT) and nitrocellulose or butyl phthalate and nitrocellulose.[3]. Based on its sensitivity, it is divided into two : Initiating Explosive; Non-initiating Explosive; The examples of Explosive Chemicals. During World War II it was extensively used by the British Special Operations Executive (SOE) at Aston House for sabotage missions. Table 1 Table. transport in accordance with the department of transportation regulations for class a explosives. Captured SOE-supplied Nobel 808 was the explosive used in the failed 20 July plot assassination attempt on Adolf Hitler in 1944. While Composition C-3 had a much wider serviceable temperature range than Composition C, it could not be s… It is a cast-cured explosive composition made from a homogeneous mixture of RDX in a plasticized polyurethane rubber matrix. It also opened the way to begin study of new non-explosive low-toxicity plasticisers (esters of dicarboxylic acid) and binder (branched polymers). It had the appearance of green plasticine with a distinctive smell of almonds. production. Cannons, canes, pistols or other devices designed for use otherwise than with paper caps. Pursuant to the provisions of section 841(d) of Title 18, United States Code, and 27 CFR 55.23, the Director, Bureau of Alcohol, Tobacco and Firearms, must publish and revise at least annually in the FEDERAL REGISTER, a list of explosives determined to be within the coverage of 18 U.S.C. obtain approval for appropriate safety agency before disposal. [2] While Composition C-3 had a much wider serviceable temperature range than Composition C, it could not be stored at elevated temperatures. Plastic explosive is a soft and hand-moldable solid form of explosive material. [8]:8–111, A 1.25 lb demolition charge of C4 explosive, A Marine shapes a charge of C4 to cut through solid steel at a demolitions range, "Plastique" redirects here. Plastic explosives are especially suited for explosive demolition. at 2 rpm and 21° C.) the explosive composition has a viscosity from about 50,000 to 300,000 cps, preferably from 75,000 to 200,000 cps and, most preferably from 100,000 to 150,000 cps. TCM: Improvised Explosive and Incendiary Devices California Fire Fighter Joint Apprenticeship Committee 2 Detacord® – a brand name for a detonating cord manufactured by Ensign Bickford Company. Together with RDX, these incorporate various plasticizers to decrease sensitivity and make the composition plastic. C4 has a detonation velocity of 8092 m/s (26550 ft/s) at high density and velocity of 7550 m/s (24770 ft/s) at low density 1.48 g/ml. The original use of Nobel 808 supplied by the SOE (see § History) was for sabotage of German installations and railways in Occupied Europe. Composition C was superseded by Composition C2, which used a mixture of 80% RDX and 20% plasticizer. The two-component explosive composition remains cap sensitive to a No. It has a density 1.48–1.60g/ml, does not become hard even at −55 °C (−67 °F), and does not exude at +77 °C (171 °F).
