What is IEC 61000-4-6:2019?

The IEC 61000-4-6:2019 is an international electromagnetic compatibility (EMC) standard published by the International Electrotechnical Commission (IEC). It provides guidelines and testing methods for immunity testing of electrical and electronic equipment to conducted disturbances induced by radio-frequency fields.

Scope of IEC 61000-4-6:2019

This standard specifies the test requirements and procedures for evaluating the immunity of electrical and electronic equipment when subjected to conducted disturbances induced by RF fields. The scope encompasses various aspects such as frequency range, test levels, and performance criteria for the evaluation of immunity.

Test Procedures and Requirements

The IEC 61000-4-6 standard outlines specific test procedures to determine the immunity of equipment to conducted disturbances. These tests involve subjecting the equipment to different frequencies and field strengths while monitoring its performance. The standard also defines the acceptance criteria based on which the equipment's immunity is evaluated.

It further describes how to set up the test environment, specify the test equipment, and provides guidance on conducting the tests. This includes generating the required RF disturbances, measuring the equipment's response, and interpreting the results accurately.

Benefits and Application

The IEC 61000-4-6 standard is essential for manufacturers, designers, and users of electrical and electronic equipment. Compliance with this standard ensures that the equipment can function in the presence of RF disturbances commonly encountered in real-world environments.

By following the guidelines provided by IEC 61000-4-6, manufacturers can design and produce equipment that meets the necessary quality standards, thereby reducing the risk of malfunction or interference caused by RF fields. Users can also rely on this standard to assess the immunity of the equipment they purchase, ensuring its reliability and performance.

In addition, adherence to IEC 61000-4-6 helps maintain electromagnetic compatibility, mitigating interference issues between different types of electrical and electronic devices. This is especially crucial in sectors such as telecommunications, automotive, aerospace, and healthcare where multiple devices are used simultaneously.
