IEC/EN 61000 EMC Series
IEC 61000, adopted in Europe as the EN 61000 series, is the family of standards covering electromagnetic compatibility. It defines emission limits, immunity test methods and generic requirements so that electrical and electronic equipment can operate correctly without causing or suffering electromagnetic interference.
Key Takeaways
The 61000 series is the core family of electromagnetic compatibility standards.
It is published internationally as IEC 61000 and in Europe as EN 61000.
Parts cover harmonics and flicker, immunity test methods and generic environment requirements.
The 61000-4 parts define the immunity tests widely cited on rugged device datasheets.
The series is divided into parts. The 61000-3 parts address limits such as harmonic current and voltage flicker, the 61000-4 parts define immunity testing and measurement techniques, and the 61000-6 parts set generic emission and immunity requirements for given environments.
The 61000-4 parts are frequently quoted on equipment datasheets. They include electrostatic discharge, radiated and conducted radio frequency immunity, fast transient bursts, surge and voltage dips, each simulating a disturbance the equipment may encounter in service.
The 61000-6 generic standards specify the immunity and emission levels expected in residential, commercial and industrial environments, while the 61000-3 parts limit the disturbances a device may inject back into the supply.
Rugged computers and panel PCs operate near motors, radios and switching equipment, so strong performance against the 61000-4 immunity tests indicates that a device will keep working reliably in electrically noisy industrial and vehicle environments.
Frequently Asked Questions
Electromagnetic compatibility, including emission limits, immunity test methods and generic environment requirements.
They define immunity test methods, such as electrostatic discharge, radio frequency immunity, fast transients and surges, used to assess how equipment withstands electromagnetic disturbances.
Yes. EN 61000 is the European adoption of the international IEC 61000 standards.
Each part represents a specific immunity test, so listing them shows the range of electromagnetic disturbances the device has been verified against.
