Rotary Friction Test Apparatus

This test apparatus is designed to provide a quantitative assessment of the friction sensitivity of a wide range of solid explosives. Unlike the mallet friction test there is no element of impact in the stimulus.

Although any wheel and block materials of interest can be used, the standard test uses mild steel blocks and wheels of standard surface roughness. Results are expressed relative to those for standard RDX. Equipment is designed to the Sensitiveness Collaborative Committee SCC Test No.33 and also to the modern requirements of the Energetic Materials Testing and Assessment Policy Committee (Dedence Ordnance Group) Manual of Tests (EMTAP).
