IEC 62493
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.
