IEC TS 62607的这一部分建立了确定电气钥匙的标准化方法 控制特性 –由石墨烯基材料（如石墨烯薄片）组成的粉末的体积电阻率 石墨烯和/或还原氧化石墨烯，在通过 –使用粉末电阻率测量系统的四探针法。 体积电阻率是衡量粉末型石墨烯产品质量的电学性质，反映了粉末型石墨烯颗粒中的密度依赖性。 体积电导率可以直接由体积电阻率导出。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC TS 62607 establishes a standardized method to determine the electrical key control characteristic – volume resistivityfor powder consisting of graphene-based material like flakes of graphene, few layer graphene 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.All current amendments available at time of purchase are included with the purchase of this document.
