A screening test was developed that can be used to decide if a new synthesized/formulated explosive might warrant further development. The test consists of a rate stick composed of 12.7 mm diameter by 12.7 mm high pellets of different densities ordered from lowest to highest, with ignition occurring at the low‐density end of the stick. This “Poly‐rho” test yields detonation velocities over a range of densities using only the small amount of the explosive typically generated by the synthetic organic chemist at an early stage of the scale‐up process. The amount of material required is far less than that required for the typical rate stick series. Poly‐rho tests on two explosives commonly used at Los Alamos National Laboratory, PBX 9501 and PBX 9502, were conducted and the results compared with empirical detonation‐theory predictions and others’ explosive experiments. There was good agreement in both cases.
