Full title and description

Electromagnetic compatibility (EMC) - Part 2-5: Environment - Description and classification of electromagnetic environments. This IEC Technical Report provides guidance for describing and classifying electromagnetic environments, introduces the concept of disturbance degrees, defines location classes and attributes, and compiles compatibility levels and background information to support the selection of immunity requirements for equipment, sub-systems and systems.

Abstract

IEC TR 61000-2-5:2017 (3rd edition) is a guidance document that helps standards writers, test engineers and designers assess and specify immunity requirements by: introducing disturbance-degree concepts, classifying environments into location classes, describing relevant electromagnetic phenomena (radiated and conducted), and providing tables of compatibility levels applicable to those location classes. The edition updates radiated-environment descriptions for recent communication technologies and expands descriptions of conducted phenomena.

Scope

This Technical Report gives guidance for those developing immunity requirements and selecting immunity levels. It applies to any electrical or electronic equipment, subsystem or system operating in the locations described in the document. The report introduces disturbance degrees for each electromagnetic phenomenon, classifies environments into location classes with descriptive attributes, provides background on likely electromagnetic phenomena in those environments, and compiles tables of compatibility levels relevant to the location classes. The third edition replaces the 2011 edition and incorporates updates reflecting recent communication technologies and more detailed descriptions of conducted phenomena.

Key topics and requirements

• Definition and use of "disturbance degrees" to characterise severity of electromagnetic phenomena.
• Classification of environments into location classes (attributes and examples) to support realistic immunity specifications.
• Descriptions of radiated and conducted electromagnetic phenomena relevant to equipment operation (including updates for modern communication technologies).
• Tables of compatibility/immersion levels and guidance for selecting appropriate immunity levels for different location classes.
• Background information for standards writers and test developers to improve specification of immunity requirements.

Typical use and users

Used by standards developers, EMC engineers, test laboratories, product designers, system integrators and regulatory or certification bodies to define or interpret immunity requirements and to select compatibility levels appropriate to specific operating environments (residential, commercial, industrial, utility, transport, etc.). It is applicable for equipment, subsystems and systems that must meet EMC/immunity expectations in defined location classes.
