Standardized procedures for measurement and evaluation of data obtained in the underwater explosion test are needed to make possible comparisons of data obtained at different laboratories. In this paper specifications for the pressure gage and instrumentation as well as calibration and the use of a standard reference explosive are discussed. Evaluation standards for peak pressure, impulse, shock wave energy and bubble energy are suggested. A practical method for determination of the water shock energy lost when the primary shock travels from the charge to the gage is given, making it possible to determine the total expansion work performed by an explosive in an underwater explosion test. Performance predictions in rock blasting for explosives based on data obtained in the underwater explosion test are also discussed.
