Available in PDF, EPUB and Kindle. Book excerpt: "The drop weight impact test is the simplest and easiest test that can be performed on small quantities of explosives or propelants, and yet it has only a minimal role in assessing explosive sentitivity or performance. This report examines the drop weight impact test as it is currently used, describes its major flaw, and suggests an alternative test that holds the promise of providing the impact energy required to ignite an energetic material. Other impact tests are described. One of these, the Ballistic Impact Chamber Test, measures the rate of reaction and extent of reaction during impact. This test demonstrates that during impact there are two forms of initiation reactions that occur; one that is very fast and is likely due to direct impact-shear initiation of the crystalline solids in the sample and, the other, a much slower component, is thought to arise due to burning of the sample."--Report documentation page

This book was released on 2005 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding and predicting the impact response of explosives and propellants remains a challenging area in the energetic materials field. Efforts are underway at LLNL (and other laboratories) to apply modern diagnostic tools and computational analysis to move beyond the current level of imprecise approximations towards a predictive approach more closely based on fundamental understanding of the relevant mechanisms. In this paper we will discuss a set of underlying mechanisms that govern the impact response of explosives and propellants: (a) mechanical insult (impact) leading to material damage and/or direct ignition; (b) ignition leading to flame spreading; (c) combustion being driven by flame spreading, perhaps in damaged materials; (d) combustion causing further material damage; (e) combustion leading to pressure build-up or relief; (f) pressure changes driving the rates of combustion and flame spread; (g) pressure buildup leading to structural response and damage, which causes many of the physical hazards. We will briefly discuss our approach to modeling up these mechanistic steps using ALE 3D, the LLNL hydrodynamic code with fully coupled chemistry, heat flow, mass transfer, and slow mechanical motion as well as hydrodynamic processes. We will identify the necessary material properties needed for our models, and will discuss our experimental efforts to characterize these properties and the overall mechanistic steps, in order to develop and parameterize the models in ALE 3D and to develop a qualitative understanding of impact response.

Download or read book Measurement of Critical Diameter Shock and Impact Sensitivity of a Special Propellant written by WHITTAKER CORP NORTH HOLLYWOOD CA SHOCK HYDRODYNAMICS DIV. and published by . This book was released on 1981 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental investigation of the critical diameter, and shock and impact sensitivity of the LOVA-X1A propellant are described. The detonation velocity was determined as a function of charge diameter for the propellant. The critical diameter lies between 0.245 and 0.375 in. for the bare charge. The shock sensitivity for initiating detonation in the propellant was determined by a gap test technique. The results, together with the results of projectile impact tests on solid disks of the propellant determined earlier, are discussed and examined in terms of the sensitivities of materials given in the literature. The critical initiating shock pressure and critical ignition energy are estimated. It is shown that the LOVA-X1A propellant is relatively insensitive to initiation compared to most cast explosives and propellants in use today. The sensitivity of stacked small grains of the propellant to projectile impact was also determined. The tests showed that the response of the grains at a large projectile diameter was always deflagration; whereas at small diameters no sustained reaction was produced. No detonation was produced by the impact. Recommendations for additional studies are given.

Available in PDF, EPUB and Kindle. Book excerpt: The Manual of Tests and Criteria contains criteria, test methods and procedures to be used for classification of dangerous goods according to the provisions of Parts 2 and 3 of the United Nations Recommendations on the Transport of Dangerous Goods, Model Regulations, as well as of chemicals presenting physical hazards according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). As a consequence, it supplements also national or international regulations which are derived from the United Nations Recommendations on the Transport of Dangerous Goods or the GHS. At its ninth session (7 December 2018), the Committee adopted a set of amendments to the sixth revised edition of the Manual as amended by Amendment 1. This seventh revised edition takes account of these amendments. In addition, noting that the work to facilitate the use of the Manual in the context of the GHS had been completed, the Committee considered that the reference to the "Recommendations on the Transport of Dangerous Goods" in the title of the Manual was no longer appropriate, and decided that from now on, the Manual should be entitled "Manual of Tests and Criteria".
