Title: Dispelling the CE Mark Myth: Whats Required for European Compliance December 12, 2003
1Dispelling the CE Mark MythWhats Required
for European ComplianceDecember 12, 2003
2What is EMC?
- EMC Electromagnetic Compatibility
- Emissions Unwanted radiated and conducted
electrical energy - Immunity Undesirable response to external
electrical energy - EMI Electromagnetic Interference
3Elements of an EMI Situation
- Source "Culprit"
- Coupling method "Path"
- Sensitive device "Victim"

PATH
4How Does EMI Affect Electronics?
- Radiated and conducted interference
- Conducted Interference Enters and Exits Equipment
through Wiring and Cabling - Radiated Interference Enters and Exits Equipment
through Wiring and Enclosure Penetration
Radiated Susceptibility
Radiated Emissions
Conducted Susceptibility
Conducted Emissions
5Radiated Coupling Field to Cable
Electromagnetic Wave
Radio
Patient Monitor
VCM
6Interference to TV Reception
No Interference
Two Interfering Signals Injected into TV
7Transients
- Electrostatic Discharge Transient Pulses
- ESD can induce glitches in circuits, leading to
false triggering, errors in address data lines
and latch-up of devices - Upset
- Damage
- Degradation leading to future failure(s)

10EUROPEAN REQUIREMENTS
11Top US Markets
12OVERVIEW OF EUROPEAN REQUIREMENTS
- Terms and Definitions
- Comparison with US Standards
- Options for Conformity
- Technical Requirements
- Use of the CE Mark
13TERMS 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
14REASONS FOR COMPLIANCE
- Regulatory Requirements
- Domestic
- EMC FCC Requirements
- Penalties
- 7000/occurrence
- Bellcore
- European
- EMC EMC Directive
- Military/Aerospace
- Functionality and Mission Success
-
15NEW 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
16EUROPEAN DIRECTIVES
17THE 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 products conformance
18APPLICATION OF THE EMC DIRECTIVE
- Electrical Apparatus Covered
- Exceptions components, large installations and
devices that must comply with other Directives
that address EMC (e.g., telecommunications) - Member states adopt ENs
- Penalties for non-compliance
- Country-by-Country basis.
- Example UK Requirements
- Fines up to 5000
- Up to 3 months imprisonment for misuse of CE mark
- Forfeiture of equipment
19COMPLIANCE WITH EUROPEAN DIRECTIVES
- Product-Specific Standards
- or use
- Generic Standards
- Use Generic Requirements if Product-Specific
Standards do not exist - Conformity Assessment Options
- Declaration of Conformity
- Technical Construction File
20CE 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
21RTTE
- Covers the following aspects
- Efficient use of spectrum
- EMC
- Safety
22RTTE 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 SME

31Surge Coupling
- Lightning and pulse sources cause high-energy
transients into power and data cables
32Voltage Dips Interrupts
- IEC 1000-4-11
- Simulates brownouts and blackouts on equipment
operation - Voltage Dip
- Voltage Interrupt
33A Testers Perspective
- Radiated Emissions Consumes at least 1/2 of all
testing and re-engineering time required for
passing most EMC programs - Most Common Failures (in approximate order of
occurrence) - 1. Radiated Emissions
- 2. Conducted Emissions
- 3. ESD
- 4. Radiated and/or conducted immunity
- 5. Surge
- 6. EFTs
