Meaningful assessment and comparisons on the injury potentials of various types of ammunition and credible forensic reconstruction require an agreement on standard tissue simulant. Gelatine blocks are relatively inexpensive and easy to produce and they meet most of the criteria for a good terminal ballistic simulant. This research looks into the variables of preparing ballistic gelatine and their effects on penetration resistance. It was found out that consistent quality gelatine blocks are easy to make and that the variables like water temperature have a far smaller effect than previously thought. Also water acidity variances allowed by European Council directive on drinking water do not have any measurable effect. A proposed standard method for gelatine preparation is presented together with penetration function for verification of gelatine quality.
对各类弹药的致伤潜力进行有意义的评估和比较以及进行可靠的法医重建，需要就标准组织模拟物达成一致。明胶块相对便宜且易于制作，并且它们满足作为良好终端弹道模拟物的大多数标准。本研究探讨了制备弹道明胶的变量及其对抗穿透性的影响。结果发现，质量一致的明胶块易于制作，并且水温等变量的影响比之前认为的要小得多。此外，欧盟饮用水指令允许的水酸度变化没有任何可测量的影响。本文提出了一种明胶制备的标准方法以及用于验证明胶质量的穿透函数。
