Cylinder expansion test

The cylinder expansion test is a testing procedure to determine the work capacity of civil explosives, measured in terms of J/kg. In this test the explosive performs work in a geometry that closely matches real rock blasting conditions. The measured work capacity EG represents a fraction ç of the chemically bound energy and this fraction depends on explosive type and different additives like aluminium grains. This makes it possible to classify explosives with respect to real work capacity instead of computed numbers based on arbitrary pressure cut-offs.
