1. Electromagnetic Compatibility Directive * EMC 89/336/EEC and 2004/108/EC

2. What is EMC “Electromagnetic compatibility is the capability of electrical and electronic systems, equipments, and devices to operate in their intended electromagnetic environmemnt within a defined margin of safety, and at design levels or performance, without suffering or causing unacceptable degradation as a result of electromagnetic interference” New electronics products developed and pushed to the market:  handphones,  radio transmitters,  solid state switching devices,  computers, MP3’s,  motor drives devices …

3. Effects Effect of a big number of devices on the market:  the everyday increase of electromagnetic pollution  these devices cause emissions to the environment where they are used Result: This devices affect other electronic equipment which is susceptable to these emissions. As more microprocessors are used to replace analog or mechanical means of a product, it become apparent, that the issue of EMC cannot be ignored. Ignoring this will caused the product to suddenly malfunction or even caused damage to properties or lives.

4. EMC Directive In order to ensure that the equipments are designed to perform as close as possible in its environment, the European standards making body CENELEC (European Committee for Electrotechnical Standardization) has been mandated to produce EMC standards for use with the European EMC Directive. For telecommunications equipment ETSI (European Telecommunications Standards Institute) is the mandated standards body.

5. Free movement of goods Free movement of goods is one of the 4 basic principles in European Community (EC). Beside the free movement of goods the EC established also: – free movement of services, – free movement of capital and, – free movement of workers (people). To establish free movement of goods EU introduced the following principles: harmonization of essential requirements, mutual recognition of conformity assessment procedures, and prevention of new barriers for trade.

6. Single Market Free movement of goods is a cornerstone of the single market. The mechanisms in place to achive this aim are based on prevention of new barriers to trade mutual recognition and technical harmonisation. Member states of EC: Austria, Belgium, Czech Republic, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Ireland, Latvia, Lithuania, Luxemburg, Malta, Netherlands, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, United Kingdom; And member states of EFTA: Norway, Iceland, Lichtenstein.

Electromagnetic Compatibility Directive – EMC 1(2) At the moment there are two directives which deal with EMC: - the old one issued in 1989 (89/336/EEC), and - new one issued at the end of 2004 (2004/108/EC). The new EMC directive states that: -Member states shall issue national technical legislation up to 20 January 2007 (with validation at least from 20 July 2007), and -The provisions of the old EMC directive can be observed for all products which will be put on the market before 20 July 2009.

18. Electromagnetic Compatibility Directive – EMC 2(2) -The EMC directive was issued for the first time in 1989 and was amended with directive 92/31/EEC, and directive 93/68/EEC (so called CE marking directive). The complete name of EMC directive is: “Council directive on the approximation of the Laws of Member States relating to electromagnetic compatibility.” There are several reasons for new directive regarding EMC: change in the field of telecommunication – new directive 99/5/EC, changes in technology, new harmonized standards, …There are several reasons for new directive regarding EMC: change in the field of telecommunication – new directive 99/5/EC, changes in technology, new harmonized standards, …

19. Objectives The main objective of the EMC directive is to guarantee the free movement of apparatus and to create an acceptable electromagnetic environment in the EEA territory. In order to achieve it, a harmonised and acceptable level of protection is requested in the Directive, based on Article 100a of the Union Treaty, leading to full harmonisation in the EEA. The level of protection requested is further specified in the EMC Directive by protection aims in the field of electromagnetic compatibility. The main goals are: a)To ensure that the electromagnetic disturbances produced by electrical and electronic apparatus does not affect the correct functioning of other apparatus according to the definition of Article 1.1 of the EMC Directive (see note 8), as well as radio and telecommunications networks, related equipment and electricity distribution networks. b)To ensure that apparatus have an adequate level of intrinsic immunity to electromagnetic disturbances to enable them to operate as intended.

20. Scope and terminology 1(3) 1.‘apparatus' means all electrical and electronic appliances together with equipment and installations containing electrical and/or electronic components. 2.‘electromagnetic disturbance' means any electromagnetic phenomenon which may degrade the performance of a device, unit of equipment or system. An electromagnetic disturbance may be electromagnetic noise, an unwanted signal or a change in the propagation medium itself. 3.‘immunity' means the ability of a device, unit of equipment or system to perform without degradation of quality in the presence of an electromagnetic disturbance.

21. Scope and terminology 2(3) 4.‘electromagnetic compatibility' means the ability of a device, unit of equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment. 5.‘competent body' means any body which meets the criteria listed in Annex II and is recognized as such. 6.‘EC type-examination certificate' is a document in which a notified body referred to in Article 10 (6) certifies that the type of equipment examined complies with the provisions of this Directive which concern it.

22. Scope and terminology 3(3) (a) domestic radio and television receivers (b) industrial manufacturing equipment (c) mobile radio equipment (d) mobile radio and commercial radiotelephone equipment (e) medical and scientific apparatus (f) information technology equipment (g) domestic appliances and household electronic equipment (h) aeronautical and marine radio apparatus (i) educational electronic equipment (j) telecommunications networks and apparatus (k) radio and television broadcast transmitters (l) lights and fluorescent lamps.
