Title: What is EN 61000-4-3:2019 and EN 61000-4-9:2020?

Introduction:

EN 61000-4-3:2019 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 61000-4-3:2019?

EN 61000-4-3:2019, also known as EN 61000-4-3, is a standard that provides guidelines for the evaluation of the immunity of electrical and electronic equipment to impulse interference. This standard specifies the procedures for conducting immunity tests, which are used to measure the equipment's resistance to electrical interference caused by external sources such as lightning strikes, power line faults, and switching transients.

The main purpose of EN 61000-4-3:2019 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.

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, also known as EN 61000-4-2, sets forth a series of test methods and performance criteria to evaluate the immunity of electrical and electronic equipment to electrostatic discharge. 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 comply with the requirements of EN 61000-4-3:2019 and EN 61000-4-2:2020. These standards provide manufacturers with a framework for evaluating the immunity of their products to external sources of electrical energy, including impulse interference and electrostatic discharge. By complying with these standards, manufacturers can produce products that are safe, reliable, and durable, providing value to their customers and stakeholders.
