What is emc certification

What is EMC certification With the development of electrical and electronic technology, the increasing popularity of household appliances and electronic products, radio and television, post and telecommunications communications and computer networks are increasingly developed, the electromagnetic environment is becoming increasingly complex and deterioration of the electrical and electronic products, making the electromagnetic compatibility of electrical and electronic products (EMC EMC and electromagnetic interference EMI and electromagnetic resistance to the EMS) issues have been the increasing attention of the governments and production enterprises. Electronic, electrical products electromagnetic compatibility (EMC) is a very important quality indicators, it is not only related to the product itself, the reliability of the work and the use of safety, but also may affect the normal operation of other equipment and systems, the relationship between the protection of the electromagnetic environment. European **** body government regulations, from January 1, 1996, all electrical and electronic products must be certified by the EMC, affixed with the CE mark to sell in the European **** body market. This move has caused a wide impact in the world, governments have taken measures to implement mandatory management of the RMC performance of electrical and electronic products. Internationally more influential, such as the European Union 89/336/EEC Directive (i.e., EMC Directive), the U.S. Code of Federal Regulations CFR 47/FCC Rules, etc. are on the electromagnetic compatibility certification put forward clear requirements

EMC is the abbreviation for Electro Magnetic Compatibility.

By the way, China's CCC certification mark with EMC letters after the EMC certification

When we watch TV, if someone next to the use of hair dryers or electric shavers and other household appliances, the screen will appear annoying snowflake streaks. Electric rice cooker can not cook rice, obviously turned off the air conditioner, after a while but then start their own ...... These are common to the phenomenon of electromagnetic interference. More seriously, electromagnetic interference signals can cause unimaginable consequences if they get in the way of medical electronic equipment that is monitoring a medical condition or an airplane that is in flight.

Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate in its electromagnetic environment in compliance with the requirements and not cause intolerable electromagnetic interference to any equipment in its environment. Therefore, EMC includes two aspects of the requirements: on the one hand, it refers to the normal operation of the equipment in the process of electromagnetic interference in the environment can not exceed a certain limit; on the other hand, it refers to the apparatus of the environment in which the presence of electromagnetic interference with a certain degree of immunity, that is, electromagnetic sensitivity.

The so-called electromagnetic interference refers to any electromagnetic phenomenon that can degrade the performance of the equipment or system. And the so-called electromagnetic interference refers to the electromagnetic interference caused by the degradation of the performance of the equipment or system.

EMC includes EMI (Electromagnetic Interference) and EMS (Electromagnetic Survivability) two parts, the so-called EMI electromagnetic interference, is the machine itself in the process of the implementation of due function in the process of generating electromagnetic noise is not conducive to other systems; and EMS is the machine in the process of the implementation of the due function is not subject to the influence of the surrounding electromagnetic environment ability.
