As a basic functional material, magnetic materials are widely used. It involves electronic information, mechanical and electrical, automobile, metallurgy, aerospace, aviation, transportation, biomedicine and other departments. In electronic information, whether it is consumer electronics, industrial products or communication equipment, computers and peripherals, instrumentation, etc., a large number of magnetic materials and components are used, and they also play a pivotal role in modern military engineering. Over the years, countries around the world have been committed to the research of magnetic materials and components and the revision of standards. Countries, especially developed countries, have developed standards for magnetic materials and their components. With the development of the market economy and the need for convergence of international standards after China's accession to the WTO, it is important to understand the development dynamics of international and foreign advanced national standards, and to promote the standardization of magnetic materials and components in our country. Therefore, we make a brief introduction to international standards and the standards of foreign advanced countries to facilitate adoption.
Overview of international magnetic standards
Internationally authoritative regional and economically and technologically developed countries' standards mainly include: European Committee for Standardization (CEN); European Electrotechnical Standardization Committee (CENELEC) and other standards, as well as American national standards (ANSI), German national standards (DIN), British national standards (BS), Japanese national industrial standards (JIS), French national standards (NF), Russian national standards (TOCTP).
Over the years, Western Europe and the United States, dominated by Britain, France and Germany, have been putting a lot of energy and time on international and regional standardization activities, attempting to control the technical power of international standards for a long time, and sparing no effort to turn national standards into international standards. In order to achieve convergence between European standards and international standards, CENELEC (European Electrotechnical Standards Committee) signed a bilateral cooperation agreement with IEC in 1990. In 1991, the European Committee for Standards (CEN) also signed a technical cooperation agreement with ISO, which established the principle of international standardization priority and emphasized the cooperation of capabilities to avoid duplication of work. CEN/CENELEC tries to wait until the existing international standards are adopted, and the standardization projects undertaken by ISO/IEC or CEN/CENELEC are submitted to the two bodies for parallel approval, and after the draft standard is adopted, it is published and implemented simultaneously as an international standard and a European standard.
