METHOD FOR DETERMINING SENSITIVITY TO MECHANICAL EFFECTS OF HIGH-ENERGY SUBSTANCES Russian patent published in 2022 - IPC G01M7/08 G01N33/22 

FIELD: material research.

SUBSTANCE: invention relates to research or analysis of materials by special methods and can be used to determine the impact sensitivity of high-energy substances. The method for determining the sensitivity to impact of high-energy substances is realized by the fact that in the method for determining the sensitivity to impact of high-energy substances, consisting in the fact that the high-energy substance suspension is placed on an anvil in an assembly consisting of a pallet, coupling, anvil and striker, oil is poured, then the assembly is installed on the bed and the load is dropped onto the assembly, the impact results in compression of the medium and there is a comprehensive oil pressure on the test substance, comprehensive pressure creates “hot spots” in the test substance and on its entire surface and reaction occurs, according to which the level of sensitivity to the mechanical action of the test substance is determined in an unmilled form, and the high-energy substance is used in an unmilled form, multi-channel or granular gunpowder, explosives, high-explosive or initiating, small-sized products filled with various high-energy substances, for example: rifle or pistol cartridges, detonator caps. The test result is evaluated by the sound effect, as well as inspection and detection of defects associated with thermochemical decomposition in at least one element.

EFFECT: invention makes it possible to expand the possibilities of determining the impact sensitivity of standard and advanced explosives without changing their geometric parameters.
