  1. Harmonized standards on EMC

  2. New Approach Directive Conformity assessment procedures Product complies with all applicable NAD (and EN standards), there are no additional requirements in any member state. The product has free access to the internal market of EC.

  3. Standardisation 1(4) Harmonised EN standards (the reference numbers are published in Official Journal) are essential tool to implement requirements of NAD. Application of harmonised standards is voluntary. The European Commission gave the mandate for preparation of harmonised EN standards to following institutions: CEN (common standards and standards not in the scope of CENELEC and ETSI), CENELEC (electrotehnical standards), and ETSI (telecommunication standards).

  4. Standardisation 2(4) Harmonised standards (EN standards) raise the basic technical requirements for products covered by the NAD. If the product is designed, constructed and manufactured according to the applicable harmonised EN standards there is presumption that the product complies with the corresponding essential requirements of NAD.

  5. Standardisation 3(4) EN standards can be used for “presumption of conformity with essential requirements of NAD”, when they are published in the Official Journal of European Commission. The basic distinction between European and harmonised European standards is that harmonised European standards have to be implemented on national level without any changes and publicly announced. It is also a duty of member states to withdraw all national standards which are in contrary with harmonised standards.

  6. Standardisation 4(4) Implementation of requirements of harmonised EN standards to the product is not obligatory on contrary it is voluntary. However implementation of harmonised standards gives manufacturer a very good (the best) basis for the presumption that product fulfils essential requirements of NAD. Sometimes harmonised standards do not cover all requirements of NAD. In such cases manufacturer can implement requirements of international standards (IEC, ISO, UTI), national standards or other technical specifications.

  7. Harmonized EN standards 1(6) • Harmonised standards are European standards, which areadopted by European standards organisations, prepared inaccordance with the General Guidelines agreed between theCommission and the European standards organisations, andfollow a mandate issued by the Commission after consultationwith the Member States . • Harmonised standards in the meaning of the New Approachare deemed to exist when the European standards organisationsformally present to the Commission the European standardselaborated or identified in conformity with the mandate .

  8. Harmonized EN standards 2(6) The basic distinctions between EN standards and harmonized EN standards: • The reference numbers of harmonized standards are published in the Official Journal of EU. • Harmonized standards shall be transposed into national standards – without any changes. • Application of harmonized standards give presumption of conformity with essential requirements of New Approach Directives.

  9. Harmonized EN standards 3(6) Application of harmonized standards is voluntary, and manufacturers are free to choose any technical solution that provides compliance with the essential requirements of New Approach Directives. However, the application of requirements in harmonized standards give manufacturers presumption that their products comply with the essential requirements. Use of harmonized standards is the easiest way for the manufacturer to design products which are in compliance with requirements of the New Approach Directives.

  10. Harmonized EN standards 4(6) Harmonised EN standards (all EN standards) can be bought only at the national standardization bodies which are members of CEN/CENELEC. There is no EN standard which can be officially purchased – you can purchase BS EN, DIN EN, SIST EN, …

  11. Harmonized EN standards 5(6) Important dates in EN standards: • DOR is the date when the Technical Board confirms that the results of written vote are positive and that the EN/HD is adopted. • DOA is fixed by the Technical Board, normally six months later than dor. Normally the announcement of the existence of the new CENELEC EN/ENV/HD is made by each CENELEC member in the official national standards journal or in a similar publication at national level. • DOP is the date limit for identical/harmonized national standards corresponding to the new EN/HD to be available. • DOW is the latest date for all CENELEC members to withdraw or amend any national standards containing requirements conflicting with those of the new HD or EN, even if the publication of a new national standard on the basis of an HD is not intended.

  12. Harmonized EN standards 6(6) EN 60335-1:2002 IEC 60335-1:2001 (IEC 60335-1:2001/Corrigendum Jan. 2002) Modified CLC/TC 61 IEC/TC 61 LVD MD Household and similar electrical appliances - Safety -- Part 1: General requirements NOTE: The parts 2 in the EN 60335 series are to be read in conjunction with the edition of EN 60335-1 indicated for the relevant part 2. dor : 2002-07-02 doa : 2003-01-01 dop : 2003-07-01 + A11:2004 CLC/TC 61 LVD MD dor : 2003-09-23 doa : 2004-04-01 dop : 2004-10-01 dow : 2006-10-01 + A1:2004 IEC 60335-1:2001/A1:2004 CLC/TC 61 IEC/TC 61 LVD MD // dor : 2004-09-22 doa : 2005-01-01 dop : 2005-07-01 dow : 2007-10-01 EN 60065:2002 IEC 60065:2001 (corrigendum Aug. 2002) Modified CLC/TC 108 IEC/TC 108 LVD RTTED Audio, video and similar electronic apparatus - Safety requirements NOTE: Group Safety Publication dor : 2002-03-01 doa : 2002-09-01 dop : 2003-03-01 dow : 2007-03-01

  13. New Approach Directives and EN standards 1(7) Standardization procedure under the New Approach: • A mandate is drawn up, following consultation with the Member States. • The mandate is transmitted to European standards organisations. • European standards organisations accept the mandate. • European standards organisations elaborate a (joint) programme. • The technical committee elaborates a draft standard. • European standards organisations and national standards bodies organise a public enquiry. • The technical committee considers comments. • National standards bodies vote/European standards organisations ratify. • European standards organisations transmit references to the Commission. • The Commission publishes the references. • National standards bodies transpose the European standard. • National authorities publish references of national standards.

  14. New Approach Directives and EN standards 2(7) • The easiest way to find relation between NAD and harmonised standards is to visit internet page where we can find the lists of standards which support specific NAD’s. • Those lists are not always up-to-date – they are published periodically.

  18. New Approach Directives and EN standards 6(7) To know which harmonised EN standards can be used for presumption of conformity with NADs is very strong connected with experience and knowledge. There are many products for which you have to apply more than one harmonised EN standard or more than one NAD. One of possible solutions is to contact Notified Bodies. On the internet pages of EU you can find a “tool” called NANDO which helps you to find appropriate Notified for a specific product: http://europa.eu.int/comm/enterprise/nando-is/home/index.cfm.

  19. New Approach Directives and EN standards 7(7) Harmonized EN standards are tool which can be used by: • Manufacturers: in design phase, final inspection, conformity assessment (Module A – self certification); Notified Bodies: carrying out conformity assessment procedures; • Market surveillance authorities: carrying out market surveillance activities.

  20. Revision of harmonised standards • The principles concerning the mandate and the adoption of harmonised standards, their availability, and the presumption of conformity to the essential requirements apply also to the revised version of harmonised standards. • During the transitional period, both the old and the revised standards give presumption of conformity, provided that the conditions for this are met by both standards.

  22. Types of EMC Standards 1(3) • Product or product family standards, relating to a specific product or product family group The product standards take precedence over the generic standards and are drafted to cover the particular range of product types. These standards should refer to the Basic Standards for test methods wherever possible. It wil consist of defining what tests to carry out, what levels or limits, and what operating conditions and performance criteria to apply. These are prepared by IEC, CENELEC or CISPR.

  23. Types of EMC Standards 2(3) b) Generic Standards relating to a particular environment of use. At present these are for: (i) Domestic, Commercial and Light Industry (ii) Industrial environment

  24. Types of EMC Standards 3(3) c) Basic Standards, to provide general information and relate to the disturbing phenomena and testing and measuring techniques Basic standards do not contain limits or performance criteria. They serve as a reference for product standards and will not normally be listed in the Official Journal, but will be referred to in product or generic standards.

  25. Basic test and standards - emission • Harmonic current emission (EN 61000-3-2); • Voltage changes, voltage fluctuations, and flicker(EN 61000-3-3); • Voltage high frequency conductive disturbances (9 kHz to 30 MHz); • Radiated high frequency fields (9 kHz to 30 MHz); • Radiated high frequency fields (30 MHz to 300 MHz); • Radiated high frequency fields (300 MHz to 1000 MHz); • Emission standard for residential, commercial and light-industrial environments (EN 61000-6-3); • Emission standard for industrial environments(EN 61000-6-4).

  30. Electrical installations 1(3) Electrical installation: Group of electrical equipment associated for a given application and having co-ordinated characteristics. EMC Directive applies also to installations containing electrical and/or electronic components. 'Fixed Installation' in the broadest sense, is defined as 'a combination of several types of equipment, systems,finished products and/or components assembled and/or erected by an assembler/installer at a given place tooperate together in an expected environment to perform a specific task, but not intended to be placed on themarket as a single functional or commercial unit'.

  31. Electrical installations 2(3) The person(s) responsible for the design, engineering, and construction (assembly and erection) becomes the 'manufacturer' in the sense of the Directive, and assumes responsibility for the installation's compliance with all applicable provisions of the Directive, when takes into service. The EMC assembly instructions given by the manufacturer(s) of parts, and the whole method of installation, have to be in accordance with good engineeringpractice within the context of installations, as well as installation rules (national, regional or local) that will ensure the compliance of the whole installation with the essential requirements of the EMC Directive.

  32. Electrical installations 3(3) The measures to reduce EM effects on installations should be taken from the design to the operation of theinstallation, in particular: - During design, to define and specify the rules and measures to be taken; - During construction, to check their implementation; - During operation, to check for any modifications.

  33. EC Declaration of conformity The content of EC Declaration of conformity is defined in Annex I B in EMC directive. The elements which shall be on DoC are: • description of the apparatus to which it refers, • reference to the specifications under which conformity is declared, and,where appropriate, to the national measures implemented to ensure theconformity of the apparatus with the provisions of the Directive, • identification of the signatory empowered to bind the manufacturer or hisauthorized representative, • where appropriate, reference to the EC type-examination certificate issuedby a notified body.
