The EN/IEC 62493 standard describes how Conducted Emission measurements are performed, by using the 'Van der Hoofden' test method. The title of this standard is also: "Assessment of Lighting Equipment related to Human Exposure to Electromagnetic Fields"

Relevant Lighting Products:

  • All indoor and/or outdoor lighting equipment for illumination purposes with AC or battery power supply, which include all industrial, residential, public and street lighting.
  • Independent auxiliaries exclusively for the use with lighting equipment.

Exempted Lighting Products:

  • Lighting equipment for aircraft and airfields.
  • Lighting equipment for road vehicles (except lighting used for the illumination of passenger compartments in public transport).
  • Lighting equipment for agriculture.
  • Lighting equipment for boats/vessels.
  • Photocopiers, slide projectors.

The 'Van der Hoofden' measurement should be performed using a specifically described test-head. This can for example be the Schwarzbeck VDHH 9502 or the AFJ VDH 30. Then the emission measurement should be performed using the following parameters:

Frequency Range 6 dB RBW bandwidth Measurement time Frequency step Detector
20 kHz - 150 kHz 200 Hz 100 ms 220 Hz Peak
150 kHz - 10 MHz 9 kHz 20 ms 10 kHz Peak

The result of the emission measurement results should be used in a calculation to determine the Factor 'F'. The final value of this Factor 'F' should not exceed 0.85 for the measurements to pass.
