OVERVIEW OF EUROPEAN REQUIREMENTS • Terms • Directives • Comparison with US standards • Options for Conformity • Technical Requirements • Use of the CE Mark
TERMS & DEFINITIONS • European Directive • Legal Document adopted by EC Council of Ministers • Must be adopted into National Law by each EC member state • Does not call out technical standards; refers to private standards-making bodies to draw up product standards • European Norm (EN) • Harmonized Standard: Common Standard used for determining conformity • Committee process • ENs based on existing standards (CISPR, IEC) • Must be adopted into National Standards by each EC Member state • CENELEC (Comite Europeen de Normalisation Electrotechnique) • European Committee for Electrotechnical Standardization: responsible for generating European Norms • CE: Communaute Europeenne
TERMS & DEFINITIONS • Competent Body • Review Technical Construction Files and generate Certificates of Conformity • Must demonstrate competence in the area of the Directive • Approved by member state National Authority • Conformity Assessment Bodies (CAB) in US • Notified Body • “Notified” means that the organization has been “officially announced” to the EC and other states by National Authority
NEW APPROACH DIRECTIVES • Objective: Elimination of Technical Barriers • New Approach calls out Essential Requirements • Technical Details Left to Committees • Harmonization of European Norms (Standards) • CENELEC • Conformity to European Norms demonstrates compliance • Products meeting essential requirements eligible for CE Marking

THE EMC DIRECTIVE • 89/336/EEC: The EMC Directive • Adopted 1989 by Council of the European Communities • Original Implementation 1 January 1992 • Amended by 92/31/EEC • Affects all products to be placed on the Market • Calls out essential “protection requirements” which include emissions as well as susceptibility • Does not call out specifications or standards “New Approach Directive” • Essential Protection Requirements • Allows Self-Certification • ”CE” Marking certifying product’s conformance
EMC Directive - Changes • Clarification of scope and definitions • Simplification of compliance methods – DoC • Elimination of mandatory NB/CB examinations • Modified DoC supporting location of responsible parties by enforcement • Requirement for unique product identification • Clear treatment of fixed installations and their compliance obligations
Conformity Assessment • Manufacturer performs an electromagnetic compatibility assessment applying all relevant harmonized standards published in OJ • Manufacturer prepares technical documentation providing evidence of compliance – retains at least 10-years after date of last manufacture • Manufacturer prepares a Declaration of Conformity (DoC) • The “CE” mark may be placed on the equipment
Non-harmonized/Incomplete Application of Standards • If harmonized standards are not followed or partially followed: • Technical documentation is more complex to justify the DoC describing the steps taken to meet the essential requirements • Review by a Notified Body to obtain an opinion on conformity • NB opinion adds weight in case of a dispute but does not solely authenticate the DoC
Product Identification • Each apparatus to be identified in terms of type, batch, serial number or other information allowing identification • Each apparatus shall be accompanied with Community contact information • Information must be provided on specific precautions for EMC protection (e.g., installation instructions, shielded cable use, etc.) • Use restrictions for items where residential compliance is not ensured • Information on use for intended purpose included with the apparatus
Fixed Installations • Special section – Article 13 • Applies to a given fixed installation with the apparatus not commercially available • CE marking and mandatory pre-testing not required • Installation requires application of “good” engineering practices with documentation of EMC precautions incorporated • If EMC problems are indicated, authorities may request evidence of compliance • If non-compliance is established, appropriate measures to attain compliance may be imposed
CE Marking • Implementation of the CE Marking: • Must be affixed to: • Product • Packaging • Instructions for use, OR • Guarantee certificate • Can be used with other marks providing they do not reduce the visibility and legibility of the mark • The marking may include: • The identification of a notified body involved in assessment
R&TTE • Covers the following aspects: • Efficient use of spectrum • EMC • Safety
R&TTE Approval Process • CE Marking by manufacturer is allowed • Self-Declaration for many products • Reduced approval procedures and processes • Harmonized standards developed • Faster, cheaper, more market coverage for Small – Medium Enterprises
Annexes • Annex I: Things NOT covered • Cables, Receive-only broadcast, Kits, Aviation and Air Traffic, marine • Annex II: Internal Production Control • Basis for all Annexes (good documentation!) • Annex III: Annex II + Testing • Type testing • Annex IV: TCF • Notified Body/CAB (for new technologies) • Annex V: Full QA • Accredited Quality Assurance System
R&TTE Testing • No longer requires involvement of accredited test house • Test to harmonized standards • DoC • CE Marking • Ship • Non-harmonized frequencies: • Notification to Spectrum Authority • Alert Signal (Equipment Class Identifier) • Restricted Geographical Area
EMC Test Standards • Product specific test standards establish requirements and typically point to test method standards. Normally include: • Radiated Emissions – CISPR 22 • Conducted Emissions – CISPR 22 • Harmonic Emissions – EN 61000-3-2 • Flicker – EN 61000-3-3 • Electrostatic Discharge – EN 61000-4-2 • Radiated Immunity – EN 61000-4-3 • Electrically Fast Transient Immunity – EN 61000-4-4 • Surge Immunity – EN 61000-4-5 • Conducted Immunity – EN 61000-4-6 • Magnetic Immunity * - EN 61000-4-8 • Voltage dips/interrupts – EN61000-4-11
