The English abbreviation for electromagnetic field radiation is also EMF.
At present, electromagnetic radiation involving various industries has become another major pollution after air pollution, water pollution and noise pollution. With the renewal of the technological revolution and new applications of different wavelength bands, the exposure levels of many frequencies of electromagnetic radiation have increased significantly. . Although different countries have different views on the health hazards caused by electromagnetic radiation, their harm to the public is recognized.
The World Health Organization WHO established the International Electromagnetic Emissions (EMF) program in 1996 to propose the effects of static electromagnetic fields in ultra-low frequency (ELF), intermediate frequency (IF) and radio frequency (RF) electromagnetic fields (0Hz-300GHz) on human health.
The public's exposure to electromagnetic fields was recommended in the EU Council's recommendation of July 12, 1999 (1999/519/EC). And in May 2003, the European Electrical Apparatus Standards Committee (CENELEC) announced the new technical standard EN50366. This standard regulates the measurement and evaluation methods of electromagnetic fields generated by home appliances.
On April 29, 2004, the requirements of EN50366 were officially listed in OJEU, and this standard has become one of the LVD (Low Voltage Directive) certification projects for household appliances and other products.
On December 1, 2008, the standard EN 50366 was updated to EN 62233:2008 and enforced.
EMF is different from EMC. EMF is to ensure the safety of personal life. It is to study the influence of electric field and magnetic field noise emitted by electronic products on the human body. EMC is mainly for the purpose of ensuring the normal operation of electronic products, in order to study the impact of noise emitted by electronic products on other electronic products, or from other electronic products.
When exporting to Europe, home appliances generally meet three certification requirements: LVD+EMC+EMF+ROHS.
Induced electromotive force
EMF (ElectroMotive Force) is an abbreviation for induced electromotive force. Commonly used in the field of motor drive and power electronics
