Zusammenfassung:	A test-rig 10 for assessing the performance of a liquid-jet barrelled disruptor comprises a mount 20 for supporting a disruptor at a predetermined stand-off from an impact surface 16. The total linear momentum delivered by the jet at the impact surface 16 may be measured using a ballistic sled 12 and the central axial impulse load of the jet may be measured using a pressure gauge 18, such that a coherence metric, which characterises how focussed the jet is, can be derived. A method for assessing the performance of a liquid-jet barrelled disruptor is also described.
