Electromagnetic compatibility EMC directive introduction and product range (2014/30/EU Electromagnetic Compatibility Directive)


What is EMC EMC?

EMC (Electromagnetic Compatibility Directive), electromagnetic compatibility directive.

The EMC Directive is numbered 2014/30/EU and will enter into force on April 18, 2014. The old EMC Directive 2004/108/EC will be abolished on April 20, 2016.

With the development of electrical and electronic technology, household appliances are increasingly popular and electronic, radio and television, postal and telecommunications and computer networks are increasingly developed, and the electromagnetic environment is increasingly complicated and deteriorated, making electromagnetic compatibility of electrical and electronic products (EMC electromagnetic interference EMI and Electromagnetic anti-EMS) issues are also receiving increasing attention from governments and manufacturing companies. The European Community Government has stipulated that from January 1, 1996, all electrical and electronic products must pass the EMC certification and be affixed with the CE mark before they can be sold in the European Community market. The move has caused widespread influence in the world, and governments have taken measures to enforce mandatory management of RMC performance of electrical and electronic products. According to the European Union's Electromagnetic Compatibility (EMC) Directive 83/336/EEC, all electrical and electronic products sold in the EU market must comply with EU legal requirements in terms of their interference with other products and the immunity to external influences.

In addition to the dangers against machinery, the EU has enacted the 89/392 Machinery Directive: in order to accommodate the permissible levels of electromagnetic interference in the member states of the European Union, the Council of the European Union announced on 3 May 1989 that electromagnetic compatibility between Member States The regulation of sexual related laws—Electromagnetic Compatibility Directive 89/336EEC, referred to as the EMC Directive, was subsequently revised by 92/31/EEC, 93/68/EEC.

EMC Definitions Before describing the process that complies with the EMC Directive, define EMC as follows:

When a device or device is operated simultaneously with other devices, it does not affect the ability to work properly due to electromagnetic interference problems. Also includes:

EMI (Electromagnetic Interference) / electromagnetic interference:

A device or device that has an unfavorable function during operation. This signal is unwanted and meaningless. It may come from outside or from itself.

Electromagnetic interference can be divided into two directions:

Conducted Emission (CE): Conducted Emission

RE (Radiated Emission): Radiation Radioactivity

EMS (Electromagnetic Susceptibility): The ability of a device or device to be unaffected by the surrounding electromagnetic environment during operation.

Electromagnetic tolerance can be divided into two directions:

CE (Conducted Susceptibility): Conducting radioactivity

RE (Radiated Susceptibility): Radiation

EMC compliance EMC certification scope


According to the Directive Article 2.1, the EMC Directive applies to all devices that are prone to electromagnetic interference, or devices whose functions are susceptible to electromagnetic interference.

The instruments and equipment listed in the three EMC directives are as follows:

Home radio and television receiver

Industrial manufacturing equipment

Mobile radio

Mobile radio and commercial mobile phone

Medical and scientific equipment

Information technology equipment

General electrical appliances and household appliances

Aviation and marine wireless equipment

Educational electronic equipment

Telecommunications network and instruments
