This document specifies the requirements for the laboratory testing of the resistivity of specially prepared specimens of plastics rendered conductive by the inclusion of carbon black. The test is suitable for materials of resistivity less than 106 Ω⋅cm (104 Ω⋅m). The result is not strictly a volume resistivity, because of surface conduction, but the effects of the latter are generally negligible.
