Electromagnetic fields (EMF) test laboratory

Article: Electromagnetic fields (EMF) test laboratory

Electromagnetic fields, field distribution, etc.

We offer test procedures to record and analyse magnetic fields and their field distribution as well as tests for protection of persons from magnetic fields during test and examination routines conducted in the laboratory and on track.

Accredited test procedures

  • Our test laboratory in Munich is accredited by Deutsche Akkreditierungsstelle GmbH (DAkkS) in the area of EMF testing on rail vehicles in accordance with DIN EN ISO/IEC 17025.
  • The accreditation encompasses the test procedures outlined in the details. See also the appendix for the accreditation certificate.
  • DB Systemtechnik is QMS certified to the ISO 9001 standard.

The detailed and latest list of activities/test procedures in the flexible scope of accreditation in the testing laboratory "EMF" can be found in this PDF:

Our tests and test quantities


We can realise the following test procedures:
Measurement and analysis of 16.7 Hz magnetic fields*):

  • Measurement of electromagnetic fields (16.7 Hz) for expansive (railway) equipment
  • Correlative procedure with the possibility of carrying out assessments over an extended monitoring period (e.g. 24 hours)

Determination of localised magnetic field distribution in the area of rail power systems (protection of persons):

  • Recording of electromagnetic field loads at selected positions
  • Evaluation of fields in line with different specified limits (e.g. GUV, ICNIRP, 1999_519_EG, 2013/35/EU)

Testing of electric, magnetic and electromagnetic fields with a view to protecting persons*):

  • Measurement i.a.w. EN 50500 in the area of infrastructure and in vehicles
  • Evaluation of fields in line with different specified limits (e.g. GUV, ICNIRP, 1999_519_EG, 2013/35/EU)

*) Accredited test procedure (D-PL-11081-01-03)

Our stationary test facilitie


München, Völckerstraße 5


Stationary measurements

  • Interference immunity analysis of components (e.g. axle counters, GPE) against magnetic fields
  • Calibration of magnetic field probes and magnetometers
Test field
  • The superimposition of both fields results in an area with a largely homogeneous magnetic field between the two coils near the coil axis, which is freely accessible for experiments.
