This paper includes the results of the examination of the explosive detonation process development by shock wave initiation. A new method, a modified GAP test, has first been defined for examining the explosive sensitivity to shock waves. The GAP system consists of a flat shock wave generator and an attenuator of polyethylene with a determined shock adiabate. Shock sensitivity is examined for FH-5 and FP-5 explosive charges and for LKE-11 and LKE-15 cast composite explosives using the modified GAP test. The shock to detonation transition (SDT) process was tested in cast composite (LKE-70/10, LKE-11 and LKE-15) and pressed explosives (FH-5 and FP-5) for different values of the shock wave pressure. The distance to detonation and the "Pop-plot" diagram were determined for each explosive composition and shock pressure intensity after the analysis of the obtained results.
