What is IEC 61000-4-155:2019?

The International Electrotechnical Commission (IEC) is an international standards organization that develops and publishes consensus-based international standards for all electrical, electronic, and related technologies. One of the standards introduced by IEC is IEC 61000-4-155:2019.

Understanding the Scope

IEC 61000-4-155:2019, titled "Electromagnetic compatibility (EMC) - Part 4-155: Testing and measurement techniques - Radiated electromagnetic field immunity test," specifies the requirements and test methods for evaluating the immunity of electrical and electronic equipment against radiated electromagnetic fields.

This standard applies to both residential and industrial environments where electrical and electronic devices are exposed to various radiated electromagnetic fields, such as those emitted by radio transmitters, mobile communication networks, and other sources of electromagnetic radiation.

Testing and Measurement Techniques

IEC 61000-4-155:2019 lays out specific testing and measurement procedures to assess the performance of electrical and electronic equipment when subjected to radiated electromagnetic fields. The aim is to determine whether the equipment can function properly and maintain its essential performance characteristics in real-world scenarios.

The standard provides guidelines for test setups, equipment, calibration, and test levels, ensuring consistent and reliable evaluation of equipment across different testing facilities and laboratories worldwide. It also defines performance criteria that establish acceptable levels of immunity for the tested equipment.

Importance and Application

Compliance with IEC 61000-4-155:2019 is crucial for manufacturers, suppliers, and users of electrical and electronic equipment. By adhering to this standard, they can ensure that their products are resilient to radiated electromagnetic fields and can operate effectively without interference or malfunctions caused by external electromagnetic sources.

The application of IEC 61000-4-155:2019 extends to various industries, including telecommunications, IT, healthcare, automotive, aerospace, and many more. Compliance fosters interoperability, reliability, safety, and quality of electrical and electronic equipment, enabling smooth operation in diverse environments where electromagnetic disturbances may be present.

In conclusion, IEC 61000-4-155:2019 provides the necessary guidelines for testing and evaluating the immunity of electrical and electronic equipment against radiated electromagnetic fields. Compliance with this international standard is essential for ensuring reliable performance and proper functioning of equipment across various industries.
