ASSESSMENT OF THE SAFETY PARAMETERS REGARDING THE IMPACT SENSITIVITY OF HIGH EXPLOSIVES
Abstract
The present study investigates the impact sensitivity of high explosives used for civilian applications, with the primary objective of assessing key safety parameters in accordance with the requirements of Directive 2014/28/EU and the harmonized European Standard SR EN 13631-4:2005. Using a RENAR-accredited methodology (Procedure PI-84), the sensitivity to mechanical shock was determined through a series of standardized drop-weight tests performed with the Soneta BFH 12A impact testing apparatus. The explosive material analyzed, a hydrogel-type formulation delivered in cartridge form, was subjected to incremental energy levels under controlled conditions (20-C). The absence of any observable reaction across six consecutive trials at an impact energy exceeding 50 J demonstrated a high threshold for mechanical initiation, indicating a low sensitivity to impact. These results contribute to a broader understanding of explosive safety characteristics, which are critical both for regulatory compliance and for ensuring safe handling, transportation, and operational use in the field.
