IEC TR 61000-2-5:2017

Electromagnetic compatibility (EMC) - Part 2-5: Environment - Description and classification of electromagnetic environments

IEC/TR 61000-2-5:2017(E) is a Technical Report intended for guidance for those who are in charge of considering and developing immunity requirements. It also gives basic guidance for the selection of immunity levels. The data are applicable to any item of electrical or electronic equipment, sub-system or system that operates in one of the locations as considered in this document.
This Technical Report provides the following:
– introduces the concept of disturbance degrees and defines these for each electromagnetic phenomena;
– classifies into various location classes and describes them by means of attributes;
– provides background information on the different electromagnetic phenomena that may exist within the environment and;
– compiles tables of compatibility levels for electromagnetic phenomena that are considered to be relevant for those location classes.
This third edition cancels and replaces the second published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) the description of the radiated electromagnetic environment has been updated taking into account recent communication technologies;
b) some conducted phenomena and respective interference sources have been described in more detail.
