Description
IEC 61000-4-12:2017 Electromagnetic Compatibility (EMC) - Part 4-12: Testing and measurement techniques - Ring wave immunity test
Overview
EN IEC 61000-4-12 by the International Electrotechnical Commission (IEC) sets the requirements for testing an EUT (Equipment Under Test) during operational conditions to a non-repetitive damped oscillatory transients (ring wave) in low-voltage power. This phenomenon is created by switching of electrical networks and reactive loads leading to breakdown of power supply circuits. This type of waveform can also be created via lightning, which is characterized by a unidirectional waveform. This standard can be purchased at the IEC Webstore. EN IEC 61000-4-12 falls into the greater structure of EN IEC 61000 which covers broader EMC concepts.
Testing
EN IEC 61000-4-12 defines test voltage and current waveform, ranges of test levels, test equipment, test set-up, and testing procedures. A ring wave with a defined .5μs rise time and 100kHz oscillation is determined to be typical and widely used for testing products. The verification of the test generator must meet rise time (voltage and current), oscillation frequency, decay, repetition frequency, open-circuit voltage, and short-circuit current. This standard sets testing criteria based on several different levels, more exact information is provided in the standard. 
Equipment
EN IEC 61000-4-12 ring wave generators replicate the non-repetitive damped oscillatory transients (ring wave) required for this standard. Given the nature of the waveform this standard places specific requirements on EMI Test Equipment. The characteristics that are required are rise time (current & voltage), oscillation frequency, decaying, repetition frequency, open-circuit voltage, and short circuit current. We offer rental products by Teseq, Haefely, EM Test, and Thermo-Keytek. We also provide a variety of accessories for our rental equipment allowing customers to meet a variety of requirements. These EMI ringwave products come with an A2LA accredited calibration and free technical support included with the rental.
