Abstract

AbstractSulfur‐coated pin oscillographic technique (SPOT) has been developed as a new technique for measurement of shock velocity in water. Unlike other techniques, generally employing piezoelectric transducer or high speed photography, the application of this technique is not restricted to the measurement of shock wave pressures over a limited range. To illustrate the application and accuracy of the technique the detonation pressures of a few typical explosives have been measured with this technique and compared with those determined elsewhere by using other techniques. The new technique has yielded measurement of shock velocity in water within an accuracy of 2%.
