What is IEC 61000-4-6:2019?

IEC 61000-4-6, also known as Electromagnetic Compatibility (EMC) – Part 4-6, is an international standard that provides guidelines for testing and measurement techniques to assess the immunity of electrical and electronic equipment against conducted disturbances induced by radio frequency electromagnetic fields. This standard helps ensure that devices can function properly even in the presence of such disturbances.

Why is IEC 61000-4-6 important?

In today's technologically advanced world, there is a wide range of electronic devices that coexist and operate in close proximity. These devices emit various forms of electromagnetic energy that can interfere with each other. Such interference can result in malfunctions or even complete failure of equipment, leading to financial losses, safety hazards, and inconvenience to users. IEC 61000-4-6 plays a crucial role in addressing these concerns and ensuring electromagnetic compatibility.

Testing and measurement techniques

The standard defines specific procedures and methods for conducting tests to assess the immunity of electronic equipment to conducted disturbances. The tests involve subjecting the device under test to different levels of radio frequency signals across a defined frequency spectrum. The goal is to determine if the equipment can continue to function properly despite the presence of these disturbances.

The standard outlines the necessary instrumentation setup, measurement procedures, and pass/fail criteria for the tests. It provides guidance on how to apply the appropriate test signals, how to evaluate the performance of the tested equipment, and how to interpret the test results accurately.

Compliance and certification

IEC 61000-4-6 compliance ensures that electronic equipment is designed and manufactured according to internationally recognized standards, enabling their safe and reliable operation in various environments. Compliance with this standard is typically mandatory for manufacturers to legally market and sell their products in many countries.

To demonstrate compliance, manufacturers may obtain certification from accredited testing laboratories. These laboratories assess the equipment's performance against the requirements specified in IEC 61000-4-6. The certification process involves rigorous testing and evaluation, ensuring that the device meets the necessary criteria for electromagnetic immunity.

In conclusion, IEC 61000-4-6:2019 plays a vital role in promoting the electromagnetic compatibility of electrical and electronic equipment. By following the guidelines and conducting the necessary tests, manufacturers can ensure their products can withstand conducted disturbances induced by radio frequency electromagnetic fields. This leads to improved performance, reliability, and safety of electronic devices in today's interconnected world.
