The blasting product is malleable to the extent that it can be cut to length, laid out, or bundled for a wide variety of applications. Nitrate ester based explosives must contain "antacid" to the level equivalent to 1% MgCO. the waste oil is generated, characterized and used within the same province or territory; approvals have been received from the provincial authority having jurisdiction over use and transport of waste oil; its use is described in the factory licence; the products are authorized and include the limiting percentages of waste oil (not more than 50% waste oil may be used in the oil phase); explosive product use and sale is restricted to the base factory site where the waste oil originated. Must be "-" by the criteria in the UN Manual of Tests and Criteria (no fire or explosion in any of 3 trials of the test). It will enhance any encyclopedic page you visit with the magic of the WIKI 2 technology. Dictionary Geotechnical Engineering/Wörterbuch GeoTechnik, The Application of Smooth Blasting for Freezing Rock in Vertical Shaft. CEN Standard EN 13631-1:2005: Explosives for civil uses - High explosives - Part 1: Requirements (the velocity of detonation shall be at least 90% of the value quoted by the manufacturer in 3/3 trials for each means of detonation claimed by the manufacturer. With water gel explosives, filling a bomb is merely a matter of pouring the material into the casing. They contain a gelatinizing agent, also known as a thickener, that modifies their consistency, ranging from easily pourable gels to hard solids. For the purposes of fume classification, only poisonous or toxic gases such as carbon monoxide, hydrogen sulphide, and nitrogen oxides are considered. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. Monomethylamine nitrate is made from monomethyl amine (MMA) and nitric acid. The proportions of these components vary depending on the desired explosiveness of the water gel. Table 2 summarizes the tests, indicating the origin of the test and the test criteria for blasting explosives. The density of an emulsion or water gel explosive after sensitization by a chemical reaction resulting in gas. Congratulations on this excellent venture… what a great idea! Use of this website signifies your agreement to our Terms of Use. An explosive charge, usually of high detonation velocity and detonation pressure, designed to be used in the explosive initiation sequence between an initiator or primer and the main charge. Water gels are also less expensive compared to conventional explosives. ERD does not regulate the use of high explosives. The following types of explosives will not be authorized for commercial purposes: As indicated on the application form, tolerances are to be provided. Explosives with positive oxygen balances are not considered as being acceptable in these classifications. Check presence and correctness of TDG label, shipping name, PIN, manufacturers product name or part number, address, phone number. M = test performed by manufacturer to substantiate its claims on the properties of the product. In the proposed new explosiv… Certain tests, (indicated by “M” in Table 1 below) will require manufacturers to submit test results to substantiate their claims regarding the properties of the product. Tests indicated by “A” are authorization tests to be done by the CERL. An outer shipping container used for the packaging and transport of Class 1 explosives. CERL will prepare the sensitized product from unsensitized products. A classification indicating the amount of carbon monoxide and hydrogen sulphide produced by an explosive or blasting agent. They are preferable to nitroglycerin-based explosives like dynamite because they produce less noxious fumes. Notes: Commercial explosives are mixtures of chemical compounds in solid or liquid form. Tolerances for physical characteristics may be set by the company. test methods so that the oil can either be accepted or rejected before it is blended with virgin oils and before their use; companies must develop guidelines for the use and testing of waste oil and waste oil blends. (no explosion when 10-g or 100-g amount subjected to flames in the test), Determine VOD by CEN Standard EN 13631-1:2005: Explosives for civil uses - High explosives - Part 14: Determination of velocity of detonation, CEN Standard EN 13631-1:2005: Explosives for civil uses - High explosives - Part 1: Requirements (at least 90% of the value quoted by the manufacturer for the smallest diameter offered in the market or for the smallest borehole diameter recommended by the manufacturer), Determine sensitiveness to a blasting detonator by the Cap Sensitivity Test - UN 5(a), Determine transition to detonation when ignited under confinement - DDT Test - UN 5(b)(ii), Must be "-" by the criteria in the UN Manual of Tests and Criteria. High explosives will be referred to Type E explosives, and there will be three sub-types in this group: This guideline applies to Type E high explosives intended for commercial or industrial use, as well as to high explosive raw materials used for their manufacture, which have a mass explosion hazard and are classified for transport with compatibility group D or S. High explosives are materials that are characterized by a very high rate of reaction, high pressure development, and the presence of a detonation wave. Color White. The following information must be provided: Note that any testing in support of the UN classification should be supplied for review, and that acceptable test results from another test facility may be accepted in lieu of testing at CERL for these tests. CEN Standard EN 13631-1:2005: Explosives for civil uses - High explosives - Part 10: Method for the verification of the means of initiation. The gaseous products of an explosion. For these reasons, any failure or malfunction will be carefully and critically reviewed by the inspector; and since in general any defect involving testing of any important attributes constitutes failure of the article, explanations will only be considered if justified and sound.
