EU EMF Criterion (Measurement Method) Standard for Electronic and Electrical Products Announced

Electromagnetic fields (EMF) are part of the human environment. The most common electromagnetic field that exists in nature is the Earth's own and the sun's magnetic field. Magnetic fields generated by man-made systems and equipment include the radio field of mobile phones, the magnetic field of power lines, and the low frequency field of grid currents. When a television, a hair dryer, or the like, is powered on and draws current from the mains power supply, there is an electric field in and around the device. Whenever the device is turned on and powered from the mains power supply, there is an electromagnetic field at the same time. Electromagnetic fields caused by currents flowing through equipment and power lines can interfere with televisions and other devices.

Electromagnetic radiation can cause adverse effects on the human body. It is mainly manifested as dizziness, vomiting, fatigue, insomnia, heart palpitations, memory loss, and neurasthenia. It also increases the probability of children suffering from leukemia, induces cancer and accelerates the proliferation of human cancer cells, and affects the reproductive system. And the visual system seriously harms human health. Electromagnetic radiation has been included in the UN Conference on Human Environment as one of the major pollutants that must be controlled to cause pollution. In general, the magnetic field is usually more significant than the electric field to human health.

In order to protect the central nervous system tissue of the human head and trunk exposed to electromagnetic fields and reduce its adverse effects on the human body, the European Union has issued relevant measures to specify limits and measurement methods for electromagnetic fields (EMF). EU Regulations on electromagnetic field radiation (EMF) of electrical and electronic products mainly include the R&TTE Directive (1999/5/EC) and the Low Voltage Directive (LVD, 2006/95/EC). These two directives contain the electrical and electronic products for human health. Requirements, namely EMF requirements. The EMF limit is specified in Council recommendation 1999/519/EC, which specifies the maximum limit for electromagnetic fields (EMF) exposed to the frequency range of 0 Hz to 300 GHz. The measurement standards for electromagnetic radiation from different products are different, which is reflected in the list of harmonized standards for the R&TTE directive and the LVD directive.

At present, the EMF evaluation (measurement method) standards for electrical and electronic products are:


For household appliances, after December 1, 2012, the original home appliance EMF measurement standard EN 50366:2003 and its addenda A1:2006 will be replaced by the new standard EN 62233:2008, and EN 62233:2008 will be modified with IEC 62233:2005. . In other words, after December 1, 2012, EN 50366:2003+A1:2006 will no longer have inferred compliance with the EMF health requirements of the LVD Directive.

For lighting equipment, the EMF measurement method standard EN 62493:2010 issued in February 2010 for this type of equipment will be implemented on February 1, 2013. The standard adopts IEC 62493:2009.

For low-power electronic and electrical equipment (electromagnetic field in the 10MHz-300GHz range), after September 1, 2013, the original EMF standard EN 50371:2002 will be replaced by the new standard EN 62479:2010, the new standard EN 62479:2010 modified to use the IEC 62479:2010. A "low power device" refers to a device that has an available antenna power and/or an average total radiated power that is less than or equal to a low power exclusion level. The "low-power exclusion level" Pmax refers to the specific condition of the output power of the device, depending on the frequency and other variables such as the distance of the person and the radiation source, such that the radiation source does not generate more than one specific exposure level. The basic restrictions. If the output power of the device is less than Pmax, the device is considered to meet the basic limit. According to this standard, audio and video (AV) products, information technology equipment (ITE), and multimedia equipment (MME) that do not include radio transmitters are unintentional radiators, and are inherently compliant with applicable electromagnetic fields. Exposure level.

For other electronic and electrical equipment not belonging to low-power electrical and electronic equipment, home appliances and lighting equipment, the EMF measurement refers to the general standard EN 62311:2008, which adopts IEC 62311:2007.
