Abstract
A friction tester for explosive material includes a cylinder with a piston disposed therein for sliding movement along the cylinder's axial dimension. The piston includes first and second opposing faces. A plate is coupled to the piston and extends away from the first face thereof along the cylinder's axial dimension. The plate includes a portion extending from the cylinder. The plate has opposing surfaces of defined surface roughness. A sample holder disposed adjacent to the cylinder holds an explosive material sample against each of the opposing surfaces of the plate at the portion thereof that extends from the cylinder. A driver coupled to the second face of the piston drives the piston in the cylinder's axial dimension such that the plate moves relative to and against each explosive material sample.
