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

PETN 的冲击和摩擦敏感性：I. 纯和润湿材料的敏感性

季戊四醇四硝酸酯 (PETN) 是一种敏感且易爆的炸药。PETN 运输时用水润湿 (25%) 以限制其冲击和摩擦敏感性。关于其含水量函数的敏感性的文献存在争议，因为测量是由几个操作员和实验室进行的，因此难以比较这些值。机械灵敏度方法的文献研究显示了机械测量的弱点和问题。事实上，使用标准化机器并由单个操作员分析样品非常重要。在这项工作中，制备了含水量为 0 至 35% 的纯 PETN 样品，并通过卡尔费休滴定法测量了含水量。通过“BAM Fallhammer”和“BAM Friction Apparatus”分析灵敏度。对由此产生的趋势进行了分析和讨论，并就其对处理安全的意义进行了讨论。该研究应有助于更好地评估使用湿 PETN (10–25 %) 时的危险，以避免发生事故。
