title: Preparing ballistic gelatine--review and proposal for a standard method.
abstract: 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.
