Title: Understanding EN 61000-4-28.2000 and EN 61000-4-9:2020: A Technical Standard for Electromagnetic Immunity and Impulse Immunity Testing

Electromagnetic interference (EMI) is a significant concern for the global electronics industry. Equipment designed to operate in high-frequency environments must demonstrate immunity to EMI. EN 61000-4-28.2000 and EN 61000-4-9:2020 are two technical standards that address the issue of electromagnetic immunity. In this article, we will discuss the purpose and key requirements of these two standards.

What is EN 610004-28:2000?

EN 610004-28:2000 is a technical standard developed by the International Electrotechnical Commission (IEC) to outline the measurement and assessment of electromagnetic immunity of electrical and electronic equipment for emission levels of radio frequency disturbances. This standard sets requirements for equipment to demonstrate its performance in relation to these disturbances, ensuring reliable operation.

The Importance of EN 610004-28.2000

EN 610004-28.2000 is crucial for ensuring the reliable operation of electronic equipment in high-frequency environments. The standard defines a set of requirements for evaluating the immunity of equipment to EMI, including the use of impulse immunity tests. These tests are used to measure the equipment's resistance to sudden surges of electromagnetic energy, which can be caused by factors such as lightning strikes, power line faults, and switching transients.

What is EN 61000-4-9:2020?

EN 61000-4-9:2020, also known as Electromagnetic compatibility (EMC) – Part 4-9: Testing and measurement techniques – Impulse immunity test, is another technical standard developed by the IEC to address the issue of EMC in high-frequency environments. This standard provides guidelines for evaluating the susceptibility of electrical and electronic equipment to impulse interference.

The Purpose of EN 61000-4-9:2020

The main purpose of EN 61000-4-9:2020 is to ensure that electrical and electronic devices can withstand sudden surges of electromagnetic energy without malfunctioning or being damaged. This standard sets out specific requirements and test methods for measuring the immunity of equipment to impulses from sources such as lightning strikes, power line faults, and switching transients.

Key Requirements of EN 61000-4-9:2020

EN 61000-4-9:2020 defines key requirements for conducting impulse immunity tests, which are essential for ensuring the reliability and robustness of equipment in high-frequency environments. The standard outlines the procedures for conducting these tests, the equipment that should be used, and the environmental conditions that should be considered.

Conclusion:

EN 61000-4-28.2000 and EN 61000-4-9:2020 are two important technical standards that address the issue of electromagnetic immunity. These standards provide guidelines for evaluating the immunity of equipment to EMI and impulses, ensuring reliable operation in high-frequency environments. By adhering to the requirements outlined in these standards, manufacturers can produce equipment that is robust, reliable, and safe in the face of unexpected electrical and electronic disruptions.
