These test methods cover direct-current procedures for the determination of dc insulation resistance, volume resistance, volume resistivity, surface resistance, and surface resistivity of electrical insulating materials, or the corresponding conductances and conductivities. Surface Resistivity is expressed in ohms per square Volume Resistivity is expressed in ohms – cm. Volume resistivity is the resistance to leakage current through the body of an insulating material.
