Without the foreign advanced standards is the International Organization for Standardization (ISO) confirmed and published the standards of other international organizations, regional organizations, standards, technical and economic standards of developed countries, authoritative international standards and internationally influentialgroup of companies Advanced standard. Magnet developed regional and technical and economic criteria are: the European Committee for Standardization (CEN),European Committee for Electrotechnical Standardization (CENELEC) and otherstandards set by the American National Standards (ANSI), the German nationalstandard (DIN), British Standards (BS), Japanese Industrial Standard (JIS), the Frenchnational standard (NF), the Russian State Standard (ГОСТ) and so on.
From what we gather the relevant magnetic materials, inductors, transformers, the standard information found in the United Kingdom, France, Germany and other national standards with European standards (EN) and a larger proportion of IEC standards and the standards of the three countries there are many similarities between the title . To German standards, for example, on magnetic materials, inductors, transformers, 67 standard, 39 standard magnets directly identical with the European standard, EN standard number in the crown directly on the former DIN; have a direct equivalent of 11 standard with IEC standards in the IEC standard number before the direct crown DIN. The standards of these countries is concentrated in three areas: First, the ferrite magnet core and electronic transformers, inductors, core size standards; second is to use magnets and components quality certification standards; third measurement method and some basic standards.
