CISPR
It refers to the International Special Committee on Radio Interference. Established in 1934 as a special committee of the IEC (International Electrotechnical Commission), its purpose is to promote international trade by internationally standardizing the permissible limits and measurement methods of radio interference caused by electrical, electronic, and telecommunications equipment. The committee consists of six core members: the national committees of IEC member countries, the International Conference on Large High Voltage Electric Systems (CIGRE), the European Broadcasting Union (EBU), the European Telecommunications Standards Institute (ETSI), the International Amateur Radio Union (IARU), and the Radiocommunication Sector of the International Telecommunication Union (ITU-R). Japan became an official member of CISPR in 1953 and has participated since the 12th General Meeting in London. Currently, approximately 20 experts are registered as members and participate in the deliberations.
