What is IEC 61000-4-20:2018 ?

IEC 61000-4-18:2019 is an essential standard for ensuring the electromagnetic compatibility (EMC) of electronic equipment. The standard is developed by the International Electrotechnical Commission (IEC) and focuses on the effects of electromagnetic disturbances (EMDs) on various types of equipment.

EMDs are disruptions in the electrical signals that can cause problems for sensitive electronics, such as computers, smartphones, and other electronic devices. These disruptions can range from low-frequency interference to more severe harmonic distortions. IEC 61000-4-18:2019 provides a framework for manufacturers to test the immunity of their equipment against EMDs, ensuring that it meets the necessary performance levels.

The standard covers a wide range of topics, including the testing techniques for evaluating the immunity of equipment, the procedures for measuring the immunity of equipment, and the criteria for determining the suitability of equipment for different applications. Additionally, the standard provides guidance for manufacturers on how to identify and mitigate potential sources of EMDs in their products.

Key Provisions of IEC 61000-4-18:2019The standard is divided into several parts, each of which covers specific aspects of EMC. The following are some of the key provisions of IEC 61000-4-18:2019:

Testing Techniques: The standard provides guidelines for the testing of EMCs in various environments, including laboratory settings and field conditions. The testing techniques cover a wide range of scenarios, including EMC tests conducted on equipment during use.

Measurement of Immunity: The standard outlines the methods for measuring the immunity of equipment, including the use of specialized equipment and measurement procedures.

Identifying Potential Sources of EMDs: The standard provides guidance on how manufacturers can identify potential sources of EMDs in their products and how to mitigate these sources.

Equipment: The standard provides guidelines for classifying equipment based on their immunity to EMDs, which can help manufacturers ensure that their products are suitable for different applications.

Conclusion: IEC 61000-4-18:2019 is an essential standard for ensuring the EMC of electronic equipment. By complying with this standard, manufacturers can ensure that their products function reliably and do not pose risks to other systems or individuals. The standard provides a comprehensive framework for evaluating the immunity of equipment against EMDs and offers valuable guidance for manufacturers on how to identify and mitigate potential sources of EMDs in their products.
