What is IEC 61000-4-28:2018 ?

IEC 61000-4-18:2019 is an essential standard for ensuring the electromagnetic compatibility (EMC) of electronic equipment. The standard was developed by the International Electrotechnical Commission (IEC) and is widely recognized and adopted globally.

The scope of IEC 61000-4-18:2019 is to provide guidelines for the testing and measurement techniques of electromagnetic compatibility (EMC) at frequencies up to 400 kHz. The standard covers various aspects such as harmonics and interharmonics, mains signalling at a.c. power port, low frequency immunity tests, and more.

In addition to providing guidelines for testing EMC, IEC 61000-4-18:2019 also includes provisions for the electromagnetic interference (EMI) and radio frequency interference (RFI) that may be caused by non-sinusoidal electrical waveforms.

Key provisions of IEC 61000-4-18:2019 include the requirement for manufacturers to perform tests to determine the immunity of their equipment to various types of EMFs, such as those caused by power lines, radio transmitters, and lightning strikes. The standard also specifies the procedures for measuring the EMC performance of equipment in various environments, such as in the presence of noise.

Conclusion

In conclusion, IEC 61000-4-18:2019 is an essential standard for ensuring the EMC of electronic equipment. The standard provides guidelines for the testing and measurement techniques of EMC and covers various aspects such as harmonics and interharmonics, mains signalling, low frequency immunity tests, and more. By complying with this standard, manufacturers can ensure that their products function reliably and do not pose risks to other systems or individuals.
