What is EN 45822

EN 45822 is a technical standard that plays a crucial role in ensuring the interoperability and compatibility of electronic equipment. It provides guidelines and requirements for manufacturers, suppliers, and users to follow to ensure the quality and performance of their products. In this article, we will delve deeper into the features and importance of EN 45822.

Understanding EN 45822

EN 45822, also known as European Norm 45822, is a standard published by the European Committee for Electrotechnical Standardization (CENELEC). It specifically focuses on electromagnetic disturbances caused by equipment used in industrial environments. The standard covers a wide range of devices, such as control equipment, instrumentation, power electronics, and telecommunications equipment.

EN 45822 sets forth requirements related to the emission of electromagnetic disturbances, as well as immunity to electromagnetic interference. The aim is to ensure that electronic equipment can operate reliably without causing interference with other devices, systems, or networks. Compliance with EN 45822 helps prevent disruptions in critical operations and reduces the risk of safety hazards.

The Importance of EN 45822

The impact of electromagnetic disturbances on electronic equipment cannot be understated. Without proper regulation, these disturbances can cause malfunctions, data corruption, or even complete system failures. EN 45822 establishes clear benchmarks for the allowed levels of emissions and immunities, thereby minimizing the risks associated with electromagnetic interference.

Compliance with EN 45822 is especially significant in industrial settings where a multitude of equipment coexist. Industrial environments often involve complex electrical systems, interconnected devices, and sensitive instrumentation. For example, in manufacturing facilities, the malfunctioning of a single machine due to interference can result in costly production delays or defective products.

Adhering to EN 45822 not only benefits manufacturers and suppliers by ensuring their products meet quality standards, but it's also advantageous for end-users. By using equipment that complies with EN 45822, companies can prevent operational disruptions, improve reliability, and reduce repair or replacement costs over time.


EN 45822 sets the benchmark for electromagnetic compatibility in industrial environments. Its guidelines and requirements help establish a framework for manufacturers, suppliers, and users to ensure optimal performance and interoperability of electronic equipment. Compliance with this standard is crucial for preventing interference, minimizing risks, and maintaining the reliability of critical operations. By embracing EN 45822, we can foster a harmonious coexistence of electronic devices in today's interconnected world.
