The process of exudation of confined explosives containing TNT, and the adverse consequences and interactive effects in munitions is described. A 70 C test for prescribed times to measure the exudate from explosives under confinement is described and has been tested, as amended, for reproducibility by the Prins Maurits Laboratorium, The Netherlands. Since exudation values for TNT of a given set point and of various manufacture vary, three descriptive exudation levels are proposed in adding this test to the TNT specification. Since exudation of TNT can be controlled by existing technology with additives which also reduce cast cracking, more stringent exudation values are proposed to be added now as requirements to end-use specifications for compositions of TNT such as shell fillers. Concurrently, collection and measurement of exudation from inspected munitions under actual hot field conditions must be done to obtain a direct correlation with this test.
