Title: What is EN 61000-4-5:2019 and EN 61000-4-9:2020?

EN 61000-4-5:2019 and EN 61000-4-9:2020 are two important standards developed by the International Electrotechnical Commission (IEC) that provide guidelines for evaluating the susceptibility of electrical and electronic equipment to impulse interference and electrostatic discharge, respectively. These standards are widely used in the manufacturing of a wide range of products, including computers, smartphones, and other electronic devices.

What is EN 61000-4-5:2019?

EN 61000-4-5:2019, also known as Electromagnetic Compatibility (EMC) – Part 5: Testing and measurement techniques – Impulse immunity test, is a standard that provides guidelines for measuring the immunity of electrical and electronic equipment to impulses from sources such as lightning strikes, power line faults, and switching transients. The main purpose of EN 61000-4-5:2019 is to ensure that electrical and electronic devices can withstand sudden surges of electromagnetic energy without malfunctioning or being damaged.

Key Requirements of EN 61000-4-5:2019

EN 61000-4-5:2019 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. The standard defines key performance parameters (KPPs) such as lightning impulse voltage, time of exposure, and the probability of failure. It also provides guidelines for conducting the immunity tests.

Understanding Electrostatic Discharge (ESD)

ESD refers to the sudden flow of electricity between two electrically charged objects. It occurs when there is a difference in electric potential between the objects and results in a rapid transfer of electrons. ESD can be generated by various sources such as friction, contact, or induction. While harmless in everyday situations, ESD can cause severe damage to sensitive electronic components and systems, leading to malfunctions or complete failure.

The Significance of EN 61000-4-2:2020

EN 61000-4-2:2020 sets forth a series of test methods and performance criteria to evaluate the immunity of electrical and electronic equipment to electrostatic discharge (ESD). Compliance with this standard ensures that products are capable of withstanding ESD events without suffering detrimental effects. By adhering to these requirements, manufacturers can enhance the reliability and durability of their products, preventing costly returns, repairs, and potential safety hazards caused by ESD-induced failures.

Key Considerations and Requirements

To ensure the quality and reliability of their products, manufacturers must consider and meet the requirements of EN 61000-4-5:2019 and EN 61000-4-2:2020. These standards provide guidelines for measuring the immunity of equipment to impulses from sources such as lightning strikes, power line faults, and switching transients. By adhering to these requirements, manufacturers can enhance the reliability and durability of their products, preventing costly returns, repairs, and potential safety hazards caused by ESD-induced failures.
