Automotive EMC Directive  

Automotive EMC Directive 2004/104/EC on electrical and electronic car components, last amendment by the Directive 2005/49/EC, 2005/83/EC, 2006/28/EC and 2009/19/EG

The European Commission has published the Directive 2004/104/EC on 13th November 2004 followed by 2005/49/EC, 2005/83/EC, 2006/28/EC  and the new adoption directive 2009/19/EC on 12th March 2006 concerning the EMC of motor vehicles and their electrical and electronic components, which forms part of European legislation for automotive type approval.
The Directive 2004/104/EC, adopted by 2005/49/EC, 2005/83/EC 2006/28/EC and 2009/19/EC replaces the previous automotive EMC directive 95/54/EC, which was based on 72/245/EEC, a directive handling only the on the suppression of electrical noise from spark-ignition engines.
The directive 2009/19/EC (2004/104/EC) contains in its annexes all the technical requirements necessary to demonstrate conformity with the requirements.

Time Schedule:

  •  With effect from 01. January 2009 all devices have to comply with the Directive 2009/19/EC (2004/104/EC).


 Equipment covered by the directive:

All Electrical equipment (including telecommunications equipment) intended to be fitted to a motor vehicle is considered to be an “Electronic Sub Assembly (ESA)” and must meet the EMC-requirements of the automotive directive.

Electronic sub-assemblies (ESAs) sold as so called “Aftermarket equipment”:
Typical aftermarket equipment is an electric ice chest, a notebook power adaptor and small heating appliances for seats connected to the power supply by the cigarette lighter socket.
These ESAs, sold as aftermarket equipment and intended for installation in motor vehicles, need no type approval according to the Directive 2009/19/EC (2004/104/EC) if they are not related to immunity-related functions.
In this case a Declaration of Conformity according to the procedures of Directive 2004/108/EC or 1999/5/EC must be issued. Part of this declaration must be that the ESA fulfils the requirements defined in paragraphs 6.5, 6.6, 6.8, and 6.9 of Annex I to Directive 2009/19/EC (2004/104/EC).
This procedure may be handled in cooperation with an accredited technical service of KBA (Kraftfahrt-Bundesamt), the National Approval Authority for Germany. VDE is such an accredited technical service.

EMC-requirements oft he directive:

Directive 20096/2819/EC (2004/104/EC)

  • Electromagnetic radiation measurement
    Frequency range: 30 to 1000 MHz
  • Immunity to electromagnetic radiation
    Frequency range: 20 to 2000 MHz
    AM 80%, 1 kHz up to 800 MHz
    PM from 800 to 2000 MHz
    Different test methods e.g. BCI, TEM cell Absorber chamber or Stripline with varied measuring ranges and test requirements
  • Immunity against disturbances conducted along supply lines (ISO test pulses 1 ~ 4)
  • Emission of conducted disturbances along supply lines

VDE services:

  • All necessary testing according to the requirements of the new Directive 2009/19/EC (2004/104/EC).
  • For aftermarket equipment not related to immunity-relevant functions: testing according to section 6.5 to 6.9
