IEC 61000-4-3 Electromagnetic Compatibility (EMC) - Part 4-3: Test and Measurement Techniques - Radiated, Radio Frequency, Electromagnetic Field Immunity Testing

The IEC 61000-4-3 standard published by the International Electrotechnical Commission (IEC) applies to the requirements for immunity to radiated electromagnetic energy of electrical and electronic equipment. This standard describes the test levels and required test methods.

The purpose of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when exposed to radiated, radio frequency electromagnetic fields. The test method described here is to evaluate the immunity of an equipment or system to electromagnetic fields from radio frequency (RF) sources that are not close to the equipment under test.

IEC product committees are responsible for determining whether this immunity testing standard should be applied, and if applicable, determining appropriate test levels and performance criteria.

Immunity testing against radio frequency (RF) sources close to the equipment under test is included in the IEC 61000-4-39 standard. Particular attention is paid to protection against radio frequency emissions from digital radiotelephones and other radio frequency emitting devices.

In the IEC 61000-4-3 standard, test methods are defined for the evaluation of the effect of electromagnetic radiation on the relevant equipment. Simulation and measurement of electromagnetic radiation are not precise enough to quantify the effects. The main purpose of the test methods described in this standard is to establish sufficient repeatability of the test configuration and repeatability of test results in various test facilities. This standard provides an independent test method. It is not possible to use other test methods instead of the claim of conformity to this standard.

Briefly, the purpose of these tests is to evaluate the ability of the equipment under test to operate as intended by applying an amplitude modulated signal (1 kHz - 80 percent) to the protection, power and signal ports.

Advanced laboratories use the following types of equipment to perform these tests: radio frequency generators, amplifiers and power meters, electric field probes, semi-anechoic chambers, and transmission antennas.
