Past internal blast testing within an eight-scale loads model of a multi-bay containment structure has provided a data base for both reflected internal blast loads and long-terms gas phase pressures within a strong containment structure. These data are analyzed to determine TNT equivalence for internal blast loading, and separate values for TNT equivalence for gas phase pressures, for two plastic-bonded explosives, PBX-9404 and PBX-9502. Different values are obtained for the two phases of the internal blast loading, and both differ from values which would be estimated on the basis of heats of explosion relative to TNT.
