What is ISO 55022:2015

ISO 55022:2015 is an international standard that defines the electromagnetic compatibility (EMC) requirements for information technology equipment (ITE). It specifies the limits and methods of measurement for conducted and radiated electromagnetic emissions, as well as immunity to common-mode disturbances.

Scope and Purpose

The scope of ISO 55022:2015 includes not only standalone ITE, but also ITE that is intended to be used in residential, commercial, and industrial environments. The purpose of this standard is to ensure that ITE does not interfere with other equipment or disrupt network services due to electromagnetic interference (EMI).

Key Requirements

ISO 55022:2015 sets forth several key requirements that ITE must meet to comply with the EMC standards. These include limits on conducted and radiated emissions across various frequency ranges, as well as guidelines for assessing immunity to common-mode disturbances such as electrostatic discharge (ESD) and voltage surges.

Testing and Certification

To ensure compliance with ISO 55022:2015, ITE manufacturers typically subject their products to comprehensive testing. This involves conducting emission measurements during normal operation and analyzing immunity performance in the presence of common-mode disturbances. Upon successful completion of these tests, a product can be certified as compliant with the standard.
