EN 55022 Information Technology Equipment - Radio Disturbance Characteristics

Comprehensive Guide to EN 55022 Information Technology Equipment - Radio Disturbance Characteristics Laboratory Testing Service Provided by Eurolab

EN 55022 is a harmonized European standard that specifies the requirements for the radio disturbance characteristics of information technology equipment (ITE). This standard is part of the Electromagnetic Compatibility (EMC) directives, which aim to ensure that electrical and electronic equipment does not generate electromagnetic interference (EMI) that could affect other equipment or cause harm to humans.

1.1 Legal and Regulatory Framework

The EN 55022 standard is a key element in the EUs regulatory framework for EMC. The EMC Directive 2014/30/EU sets out the requirements for placing ITE on the European market, including compliance with EN 55022. The directive applies to all types of ITE, from desktop computers and laptops to smartphones and tablets.

1.2 International and National Standards

EN 55022 is an international standard that has been adopted by many countries around the world. It is based on the ISO/IEC 17025:2005 standard for laboratory testing and calibration. The European Committee for Electrotechnical Standardization (CENELEC) publishes EN 55022, which is equivalent to the IEC 60950-1 standard.

1.3 Standard Development Organizations

The International Electrotechnical Commission (IEC) is responsible for developing and maintaining the EN 55022 standard. The IEC is a non-profit organization that brings together experts from around the world to develop international standards for electrical and electronic equipment.

1.4 Evolution of Standards

Standards are constantly evolving to reflect new technologies and changing regulatory requirements. EN 55022 has undergone several revisions since its introduction in 1988, with the latest version (EN 55022:2010) published in 2010.

1.5 Standard Numbers and Scope

EN 55022 is a harmonized standard that covers a wide range of ITE, including:
