Overview of IEC EMC Activity and the Role of the
Advisory Committee on EMC (ACEC)IEC General
MeetingParis, France25 October 2007

• Hervé Rochereau
• Member ACEC

2
Outline

• Electromagnetic Compatibility (EMC) Activity in
  the IEC
• Role of ACEC
• Membership
• IEC Guide 107
• Overview of Types of IEC EMC Publications
• ACEC Initiatives

3
EMC Activity in the IEC

• The electromagnetic compatibility work in the IEC
  is split between two different types of
  committees
• EMC committees (TC 77 and CISPR)
• Product committees
• EMC committees prepare basic publications,
  generic standards and some product family
  standards for particular product groups
• Product committees apply the work of the EMC
  committees to their specific products
• ACEC coordinates all of the EMC work within the
  IEC and also coordinates with other
  standardization bodies

4
Role of ACEC - 1

• Provides advice to the Standardization Management
  Board (SMB)
• Coordinates the EMC work of IEC committees
• Coordinates the EMC work of the IEC with other
  organizations (e.g. ITU, ISO, OIML, etc.)
• Identifies market needs in EMC
• Publicizes the EMC work in the IEC
• Meets twice each year

5
Role of ACEC - 2
6
ACEC Membership

• Chairman
• Radasky (US)
• Representatives of TC 77 (4) and CISPR (4)
• TC 77 -- Moehr (DE), Rochereau (FR), Delaballe
  (FR), Ianoz (CH)
• CISPR -- Kerry (UK), Heirman (US), Wright (UK),
  Verholt (DK)
• Additional EMC Experts (4)
• Cheng (CA), De Jaeger (BE), Gehrmann (DE),
  Shibuya (JP)
• Representatives of product committees which deal
  substantially with EMC matters (variable number)
• Representatives of ITU, ISO, OIML and others

7
IEC Guide 107

• Title Electromagnetic compatibility -- Guide to
  the drafting of electromagnetic compatibility
  publications, 2nd edition, 1998-01
• Guide was written by ACEC and approved by the
  National Committees of the IEC
• IEC Guide 107 is being revised by ACEC to align
  with new IEC guidance dealing with horizontal
  standards
• Describes
• EMC definitions and basic EMC principles
• Organization of EMC work in the IEC
• How to develop and use EMC standards
• Types of EMC publications

8
EMC Emission Limits

• Special category of EMC standards
• Intention is to control sources of EM emission to
  establish an acceptable EMC compatibility level
• CISPR f gt 9 kHz
• SC 77A f 9 kHz
• Product committees should reference published
  limits
• Product committees should not set their own
  emission limits
• If published limits are not suitable for product
  committees, assistance from CISPR or SC 77A
  should be requested

9
Basic EMC Publications

• Give general and fundamental conditions or rules
  for the achievement of EMC -- to be used by
  product committees
• Provide general information about
• Terminology
• Descriptions and classification of the EM
  environment
• Measurement methods and test techniques
• May be standards or technical reports
• Are not dedicated to specific products or
  families
• Do not include prescribed limits or specific
  performance requirements

10
Generic EMC Standards

• Apply to products operating in a particular
  environment for which no dedicated EMC product
  standards exist
• Product committees are encouraged to apply these
  generic standards where relevant
• Provide requirements for emissions and/or
  immunity
• Reference basic test methods

11
Product or Product Family EMC Standards

• A product family for EMC covers a group of
  similar products
• EMC requirements and test procedures are
  specified
• Basic EMC test methods are applied
• More precise test performance criteria are
  indicated
• May be a separate document or a dedicated clause
  in a comprehensive product or product family
  standard
• ACEC should be notified as work begins
• EMC box should be marked on circulated documents

12
ACEC Initiatives

• IEC Guide 107 is available at no cost to IEC
  participants by downloading - EMC Zone
• Development of Short guide to IEC Guide 107
• Summarizes key aspects of IEC Guide 107
• Developed by ACEC members and produced by the
  Central Office of the IEC
• Guide can be found in the EMC Zone
• Development of an EMC product standard review
  procedure
• Are emission standards being correctly applied?
• Are immunity test levels consistently applied?

13
ACEC EMC Workshops

• ACEC has been working to improve communications
  within the IEC concerning Electromagnetic
  Compatibility (EMC)
• EMC workshops have been held at seven previous
  IEC General Meetings
• Stockholm (2000), Firenzi (2001), Beijing (2002),
  Montreal (2003), Seoul (2004), Cape Town (2005),
  Berlin (2006)
• Industry workshops have been organized by ACEC
• Cuba, China and Iran in 2002
• Brazil and Argentina in 2003
• Japan and Malaysia in 2004
• Vietnam in 2005
• Honolulu, USA in 2007
• Planned for Singapore and Romania in 2008

14
What is the IEC EMC Zone?

• An online resource for experts, non-experts and
  the public
• Initiative launched at IEC GM in Stockholm 2000
  by ACEC
• Builds on previous material available to explain
  EMC to expert and non-expert audiences
• Zone was born in June 2002
• Presentation on the EMC Zone is part of this
  workshop
