What is EN 61000-4-3:2012

EN 61000-4-3:2012 is a technical standard published by the European Committee for Electrotechnical Standardization (CENELEC). It is part of the EN 61000 series, which addresses electromagnetic compatibility (EMC) requirements for electrical and electronic equipment. In particular, EN 61000-4-3 focuses on radiated electromagnetic field immunity testing. This article aims to provide an easy-to-understand explanation of the key aspects of this standard.

Radiated Electromagnetic Field Immunity Testing

Radiated electromagnetic field immunity testing is performed to evaluate how well electronic devices can withstand exposure to electromagnetic fields in their environment. The purpose of this test is to ensure that devices operate properly and without interference when exposed to various radio frequency signals, such as those emitted by mobile phones, wireless communication systems, or other nearby electronic equipment.

Test Setup and Procedure

The test setup for radiated electromagnetic field immunity testing typically involves an anechoic chamber, which is designed to minimize reflections from walls, ceiling, and floor. The device under test (DUT) is placed inside the chamber, and antennas are used to generate and direct the electromagnetic fields towards the DUT. The test is conducted at different frequencies and power levels, simulating real-life scenarios.

During the test, the DUT performance is evaluated based on criteria such as the presence of malfunctions or degradation of its intended function. The DUT should continue to operate within specified parameters without any significant adverse effects caused by the radiated electromagnetic fields. If the DUT fails to meet the requirements outlined in EN 61000-4-3, further design improvements and modifications may be necessary.

Conclusion

EN 61000-4-3:2012 is an important technical standard that ensures electronic devices can withstand exposure to radiated electromagnetic fields in their environment. By conducting radiated electromagnetic field immunity testing according to this standard, manufacturers can identify and address any potential vulnerabilities or interference issues that may arise. Compliance with EN 61000-4-3 helps to ensure the reliability and performance of electronic equipment in diverse electromagnetic environments.
