| Zusammenfassung | We have characterized the measurement uncertainty of a setup for the dynamic measurement of pressure pulses with amplitudes in the low kbar range and with millisecond duration. The uncertainty is closely proportional to pressure, with a magnitude of 0.34% (coverage factor k = 1). In particular, we treat the safety-critical application of measuring the pressure inside an ammunition cartridge during firing, where a target uncertainty of 3% has been set by the Permanent International Commission for the Proof of Small Arms. |
