Our Test Packages

Simple

Our Large Caliber Services are structured into several Test Packages to simplify fragment ballistics for you.

Comprehensive

Each Test Package focuses on a specific set of lethality parameters. It includes the detonation tests, evaluation of the data and comprehensive performance reports.

Flexible

We know each project is unique. That's why we use the Test Packages as a starting point and will extend/adapt them to your exact needs.

01: Closed Chamber Test Package

  • Detonation of warhead in confined chamber.

  • Recovery of >90% of fragments.

  • Evaluation of fragment mass distribution & mass-dependent fragment shape distribution.

  • Optional:

    • Metallurgical fragment analysis.​

    • Detonation fracture analysis.

  • Differentiate between lethal and non-lethal fragments.

  • Evaluation of:

    • Maximum effective fragment density.​

    • Mathematical symmetry of the fragmentation pattern.

    • Cylinder-symmetry / asymmetry of fragment ejection.​
