Abstract
A new method for determining the parameters of the equation of state JWL of explosive products from experimental data is presented. The experimentally obtained values of pressure and mass velocity on the adiabat of expansion - deceleration of the explosion products are used as reference points. The values of the JWL equation of state parameters are determined using an iterative algorithm.
