This paper explores testing of semi-conductive polyurethane materials as they apply to use in EP systems. A method for measurement of volume resistivity and Electrical characteristics over time are explored in detail. A common formula for specifying resistivity is explained, as is the effect of dynamic measurement vs. static measurement. This paper is an extension of the paper presented at IS&T NIP-17 which explained basic manufacture and specification of Ionic conductive doped polyurethane as used in EP systems.
