Impact and Friction Sensitivities of PETN: I. Sensitivities of the Pure and Wetted Material

Pentaerythritol tetranitrate (PETN) is a sensitive and brisant explosive. PETN transported wetted (25 %) with water to limit its impact friction sensitivities. Literature on sensitivities in function of content controversial as the measurements were performed by several operators laboratories rendering difficult compare values. studies mechanical sensitivity methods show weaknesses problems measurements. Indeed, it important analyze sample standardized machines single operator. During this work, pure samples contents 0 35 % prepared was measured Karl-Fischer titration. The analyzed “BAM Fallhammer” Friction Apparatus”. resulting trends discussed regard their meaning for handling safety. study should help better assess dangers when working wet (10–25 order avoid accidents.
