What is EN 45822 ?

Title: Understanding EN 45822 and EN 49922: Protecting Industrial Equipment from Electromagnetic Interference

Introduction:

Electromagnetic interference (EMI) is a significant issue in industrial environments. It can cause malfunctions, data corruption, and even complete system failures in equipment. To address this challenge, the European Committee for Electrotechnical Standardization (CENELEC) publishes the European Norms 45822 and 49922. These standards provide clear guidelines and requirements for various types of electrical appliances and devices, aiming to ensure the safety and performance of the equipment while minimizing the impact on the surrounding environment.

EN 45822: Understanding the Standard

EN 45822, also known as European Norm 45822, is a standard published by CENELEC specifically focused 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 primary objective of EN 45822 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 standard establishes clear benchmarks for the allowed levels of emissions and immunities, thereby minimizing the risks associated with electromagnetic interference.

EN 45822 Compliance: The Importance of Electromagnetic Interference

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 requirements for the emission of electromagnetic disturbances and immunity to electromagnetic interference, thereby reducing 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.

EN 49922: Ensuring Safety and Performance with Electrical Equipment

EN 49922 is a technical standard that plays a crucial role in ensuring the safety and performance of electrical equipment. It provides specific guidelines and requirements for various types of electrical appliances and devices, aiming to protect both users and the surrounding environment.

The primary purpose of EN 49922 is to establish uniform criteria for the design, manufacturing, and testing of electrical equipment. These criteria cover various aspects such as electrical safety, electromagnetic compatibility (EMC), energy efficiency, and environmental impact. By following EN 49922, manufacturers can adhere to consistent quality control processes, allowing them to produce safe and reliable products that meet international standards.

Conclusion:

In industrial environments, electromagnetic interference can cause significant disruptions, leading to costly production delays, defective products, and even safety hazards. To address this challenge, EN 45822 and EN 49922 provide clear guidelines and requirements for various types of electrical appliances and devices. Compliance with these standards is essential for ensuring the safety and performance of the equipment while minimizing the impact on the surrounding environment.
