EN 55022 Information Technology Equipment Emission Testing: A Comprehensive Guide to Eurolabs Laboratory Testing Service
EN 55022 is a European Standard that specifies the requirements for the electromagnetic compatibility (EMC) of information technology equipment (ITE). This standard is part of the IEC 61000 series, which deals with EMC. The standard covers the emission and immunity testing of ITE to ensure compliance with limits for various frequency bands.
Legislative Framework
The legislative framework surrounding EN 55022 is governed by EU directives such as the Low Voltage Directive (LVD) and the Radio Equipment Directive (RED). These directives require that products comply with specific safety and performance standards, including EMC requirements. Non-compliance can result in product recalls, fines, or even cessation of trade.
International and National Standards
EN 55022 is an international standard that has been adopted by many countries worldwide. It is a harmonized standard under the EUs New Approach directives, which means it is used as a reference for conformity assessment procedures in other countries. National standards may also be developed based on EN 55022.
Standard Development Organizations
The International Electrotechnical Commission (IEC) and the European Committee for Electrotechnical Standardization (CENELEC) are responsible for developing and maintaining the IEC 61000 series, including EN 55022. These organizations ensure that standards remain up-to-date with technological advancements.
Standard Evolution
Standards such as EN 55022 evolve over time to reflect changes in technology, regulatory requirements, or industry needs. Updates may include revisions to emission limits, test methods, or frequency bands. Manufacturers and testing laboratories must stay informed about these changes to ensure compliance.
Standard Numbers and Scope
EN 55022 is the European equivalent of IEC 61000-3-2, which specifies emission limits for ITE. The standard covers a range of products, including:
Manufacturers must ensure that their products comply with specific frequency bands and limits outlined in EN 55022.
