Abstract. Coefficient of TNT equivalence can be used in performance and safety considerations. It is effectively used for evaluation of the blast performance for different high-explosives. In this study, experimental data is used to assess TNT equivalent of polymer-bonded high explosive compositions with RDX or HMX, ammonium perchlorate, aluminium, magnesium and hydroxyl-terminated polybutadiene polymer binder. The detonation velocity was experimentally determined using fibre-optical probes connected to a photo detector and a time counter. The TNT equivalency of these compositions is determined using experimental measurements of peak overpressures and impulse of air shock wave at different distances using appropriate measuring system with pencil-type piezoelectric sensors. That results were compared with experimental data for explosive charges standard melt-cast TNT in order to determine coefficients of TNT equivalence.
