This part of IEC TS 62607 establishes a standardized method to determine the electrical keycontrol characteristic
– volume resistivityfor powder consisting of graphene-based material like flakes of graphene, few layergraphene and/or reduced graphene oxide after preparation of a sample in pellet form by
– four probe methodusing powder resistivity measurement system.
The volume resistivity is a measure of the quality of powder-type graphene products in terms of electrical property and reflects the density-dependency shown in a pellet of powder-type graphene.
The volume conductivity can directly be derived from the volume resistivity.
