Electromagnetic Compatibility Directive
Electromagnetic compatibility (EMC - Electromagnetic Compatibility) Directive
Electromagnetic Compatibility EMC is the abbreviation, the so-called electromagnetic compatibility is standard products will not affect the electromagnetic interference wave operation of other products, while products with sufficient capacity to resist external interference.
Therefore, EMC must include two aspects:
EMI (Electromagnetic Interference) / Electromagnetic Interference:
A device or devices in the operation of an unfavorable functional signal the emergence of this signal is not significant and do not want, it may come from the outside also may come from equipment or device itself.
EMI test projects as follows:
Conduction (conducted interference)
Radiation (radiation interference)
Harmonic (power harmonic interference test)
Voltage Fluctuation & Flicker (voltage variation and flicker test)
Disturbance Power (interference power)
Click (Ka Li rate)
EMS (Electromagnetic Susceptibility) / electromagnetic tolerance:
A device or devices during operation without affecting the capacity of the surrounding electromagnetic environment.
Electromagnetic tolerance test items as follows:
ESD (electrostatic discharge tolerance test)
RS (radiation tolerance test)
EFT (electrical fast surge tolerance test)
Surge (lightning tolerance test)
CS (conduction tolerance test)
PMF (power frequency magnetic field tolerance test)
Dip (instantaneous voltage drops off test)
Harmonics and Interharmonics (harmonics and inter-harmonic wave tolerance test)
With the electrical and electronic technology, the increasing popularity of home appliances and electronic products, radio and television, telecommunications and computer networks become increasingly developed, increasingly complex electromagnetic environment and deterioration, making electrical and electronic products, electromagnetic compatibility (EMC electromagnetic interference EMI and electromagnetic anti-EMS) problem by governments and the growing importance of production enterprises. European government regulations, from 1996 January 1, all electrical and electronic products must pass the EMC certification, CE mark affixed only after the market in the EC. This widespread influence in the world, governments have taken measures to RMC on the performance of electrical and electronic products, mandatory management. According to the EU's Electromagnetic Compatibility (EMC) Directive 83/336/EEC, all in the EU market of electrical and electronic products must be in its other products to foreign interference and influence of anti-interference, strict compliance with EU legal requirements.
In order to reconcile the European Union Member States relating to the permitted level of electromagnetic interference, the EU Council on December 31, 2004 issued by Member States on the electromagnetic compatibility between the laws of blending - Electromagnetic Compatibility Directive (Electromagnetic Compatibility Directive , 2004/108/EC, referred to as EMC Directive), and in July 20, 2007 formally came into effect, followed by 89/336/EEC, 92/31/EEC, 93/68/EEC three amendments.
