Title: IEC 61000-4-123: 2019 - Electromagnetic Compatibility Testing and Measurement Techniques

Electromagnetic compatibility (EMC) is an essential aspect of the development and production of electrical and electronic equipment. EMC refers to the ability of a device to operate without being affected by electromagnetic interference (EMI) from other sources, such as radio transmitters, computers, and other electrical equipment.

IEC 61000-4-123: 2019 is an important international standard that defines a set of conditions for simulating realistic electromagnetic environments and evaluating the performance and susceptibility of electrical and electronic equipment. This standard specifically focuses on immunity tests for electrical and electronic equipment against electromagnetic fields caused by radio transmitters, providing guidelines for conducting the tests, test levels, and evaluation criteria to ensure that devices can function properly in the presence of electromagnetic interference.

What is IEC 61000-4-123: 2019?

IEC 61000-4-123: 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 Testing Process:

The testing process for IEC 61000-4-123: 2019 involves a series of steps to evaluate the performance and susceptibility of electrical and electronic equipment. The standard defines a set of conditions that simulate realistic electromagnetic environments, including exposure to various frequency and waveform sources.

The standard provides guidelines for conducting the tests, including the frequency and power level of the radio transmitters, the duration of the exposure, and the testing equipment. The testing equipment must be calibrated to ensure that it operates within the specified parameters and can accurately measure the immunity of the equipment.

The Evaluation Criteria:

The evaluation criteria for IEC 61000-4-123: 2019 are based on the measurement of the immunity of the electrical and electronic equipment to electromagnetic interference caused by radio transmitters. The standard defines four categories of immunity, including, , .The first category, also known as "immediate action, " requires the equipment to have a highly specified level of immunity to electromagnetic interference. The second category, also known as "related action, " requires the equipment to have a moderate level of immunity to electromagnetic interference.

The third category, also known as "marginal action, " requires the equipment to have a low level of immunity to electromagnetic interference. The fourth category, also known as "no action, " does not require any level of immunity.

Conclusion:

IEC 61000-4-123: 2019 is an important international standard that provides guidelines for conducting electromagnetic compatibility testing and measurement techniques. This standard specifically focuses on immunity tests for electrical and electronic equipment against electromagnetic fields caused by radio transmitters, providing guidelines for conducting the tests, test levels, and evaluation criteria to ensure that devices can function properly in the presence of electromagnetic interference. By subjecting electrical and electronic equipment to these tests, manufacturers can assess the performance and susceptibility of their products to electromagnetic interference and ensure that they meet the necessary requirements for operation without interference from radio transmitters or other sources.
