THE INVENTION OF A NEW TYPE OF FRICTION SENSITIVITY APPARATUS

Abstract

A new type of test apparatus was invented which obtains an absolute value in foot-pounds for the frictional energy required to ignite explosives, pyrotechnics, propellants and other high energy compositions. The device obtains the frictional energy of ignition by spinning a rod on the sample held in an alundum sample holder. This energy is calculated from the torque load, the deflection, the revolutions per minute and the time to fire. Reproducibility of test results using duplicate samples is within a 1% to 2% range.
