What is IEC 61000-4-149:2019 ?

Title: IEC 61000-4-149:2019 - A Technical Article on Electromagnetic Compatibility Testing

Electromagnetic compatibility (EMC) is a crucial aspect of product design, especially for electrical and electronic equipment (EE) that operate in various electromagnetic environments. IEC 61000-4-149:2019 is an essential international standard that defines a set of conditions to simulate realistic electromagnetic environments and evaluate the performance and susceptibility of EE devices. This standard specifically focuses on immunity tests against electromagnetic fields caused by radio transmitters, providing guidelines for conducting the tests, test levels, and evaluation criteria.

What is IEC 61000-4-149:2019?

IEC 61000-4-149:2019 is an international standard developed by the International Electrotechnical Commission (IEC) that focuses on harmonics and interharmonics, which are disturbances caused by non-sinusoidal electrical waveforms that can affect the performance of electronic devices and systems connected to the electric power network. The standard defines a set of conditions to simulate realistic electromagnetic environments and evaluate the performance and susceptibility of EE devices.

The Testing Process:

IEC 61000-4-149:2019 provides a standardized testing procedure for evaluating the immunity of EE devices to electromagnetic interference (EMI) caused by radio transmitters. The standard defines four test levels, each representing a different level of interference. These test levels are designed to simulate the interference from various sources, such as portable electronic devices, industrial machinery, and power transmitters.

To ensure the safety and reliability of EE devices, manufacturers must conduct EMC testing in accordance with IEC 61000-4-149:201The standard provides guidelines for conducting the tests, including the type of equipment to be tested, the test environment, and the testing procedures.

Conclusion:

IEC 61000-4-149:2019 is an essential international standard for evaluating the immunity of EE devices to EMI caused by radio transmitters. By subjecting electrical and electronic equipment to these tests, manufacturers can assess the performance and susceptibility of their products, ensuring that they meet the necessary requirements for safe and reliable operation in various electromagnetic environments.
