This standard specifies in detail the determination method of resistivity of carbon raw materials (such as calcined anthracite, graphite, roasted crushed, calcined petroleum coke, graphitized coke, needle coke, etc.) and coke powder. The resistivity is calculated according to Ohm's law by applying a certain pressure and current under specific conditions, measuring the voltage drop at both ends of the sample. This standard applies to the accurate measurement of resistivity of raw materials and coke powder in carbon production.
