Abstract:
The impact and friction sensitivities of explosives were measured by 12 methods used in Russia and abroad. Correlations between explosion frequency on devices No. 1 and No. 2 with a “lower sensitivity limit” according to Russian standard 4545–88 and “critical clamping pressure” for the I-6-2 device are obtained. Almost all results are well correlated with critical stress p1 thus representing a good base for explanation of experimental results for impact and friction. The values we obtained determining friction sensitivity are often proportional to $p_1$. The regularities obtained are explained.
