What is IEC 61000-4-8:2019?

IEC 61000-4-8:2019 is an international standard that addresses the immunity requirements and test methods for electromagnetic compatibility (EMC) of electrical and electronic equipment. It specifically focuses on electromagnetic fields generated by medium-frequency sources, such as power supply systems and electric trains.

Scope and Purpose

The purpose of IEC 61000-4-8:2019 is to ensure that electrical and electronic equipment can operate properly in the presence of medium-frequency electromagnetic fields without suffering from any performance degradation or malfunctioning. The standard provides a set of test procedures and criteria for evaluating the immunity levels of equipment under various electromagnetic field conditions.

Test Procedures

The standard outlines the test procedures for evaluating the immunity of equipment to continuous and transient electromagnetic fields, as well as related phenomena such as voltage dips and interruptions. These tests are intended to simulate real-life scenarios where equipment may be exposed to electromagnetic interference, ensuring that they can withstand and operate reliably in such environments.

Benefits and Compliance

Compliance with IEC 61000-4-8:2019 helps manufacturers and users of electrical and electronic equipment ensure the reliability and performance of their products in the presence of medium-frequency electromagnetic fields. By adhering to this standard, manufacturers can demonstrate the quality and safety of their products, while users can have confidence in the equipment's ability to operate effectively even in challenging electromagnetic environments.
