In June 2021, the national standard GB/T40007-2021 General Rules for Contact Measurement Method of Resistivity of Nanotechnology Nanomaterials was officially released in Taiyuan.
This standard is mainly formulated by Shanxi Institute of Coal Chemistry, Chinese Academy of Sciences. It is the first general standard for resistivity testing of nanomaterials (main powders) in the industry, including three testing methods: static four probe, dynamic four probe, and dynamic four wire two electrode. This general rule standard will provide technical support for a series of resistivity test rules and standards, and help China improve the nanomaterial testing standard system. During the formulation of the standard, experts in the field of nanomaterials discussed it for many times, and many units in the industry repeatedly tested it, making the standard highly scientific, instructive and universal. Ding Hailong, general manager of Jingge Electronics in Suzhou, was invited to participate in the standard drafting and formulation meeting.
