IEC 61000-4-3 is the International Electrotechnical Commission's immunity standard on radiated radio-frequency electromagnetic field. The publication is one of the basic EMC standards of the IEC 61000-4 series. The European equivalent of the standard is called EN 61000-4-3. The current version of the IEC standard is the third edition dated 2010-04-27. Next release (4.0) is expected to be published in June 2019. The basic standards (61000-4) are usually called by product or family specific standards, which use the these basic standards as a common reference.

Scope
The publication describes test levels and procedures regarding immunity to radiated electromagnetic fields.

requirements, levels and test methods to achieve immunity compliance of an electronic product. The purpose is to create a reproducible ground for product compliance and the standard defines: ranges, levels, test equipment, setups, procedures, calibrations, generator waveforms and general uncertainties. The intention is not to define product specific tests but instead establish a basic common reference. Product specific tests are instead defined in standards such as EN 50130-4 for alarm systems, EN 50121-4-2 for railway applications or IEC 60601-1-2 for medical equipment.

The product, or equipment under test (EUT), is seen from an operators point of view during test. The EUT is therefore in its operational mode and testing does not include storage or transportation conditions.

Test levels
The EUT is subjected to three types of discharge. Direct contact discharge is preferred ether directly to the EUT or indirectly through vertical or horizontal coupling planes. Air discharge is used where direct contact cannot be applied.
