FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61326-2-5 has been prepared by subcommittee 65A: System
aspects, of IEC technical committee 65: Industrial-process measurement, control and
automation.
This third edition cancels and replaces the second edition published in 2012. This edition
constitutes a technical revision.
This edition includes the following significant technical change with respect to the previous
edition:
– update with respect to IEC 61326-1:2020.

The text of this International Standard is based on the following documents:
FDIS Report on voting
65A/978/FDIS 65A/989/RVD
Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
This part of IEC 61326 series is to be used in conjunction with IEC 61326-1:2020 and follows
the same numbering of clauses, subclauses, tables and figures.
When a particular subclause of IEC 61326-1 is not mentioned in this part, that subclause applies
as far as is reasonable. When this standard states “addition”, “modification” or “replacement”,
the relevant text in IEC 61326-1 is to be adapted accordingly.
NOTE The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in IEC 61326-1;
– unless notes are in a new subclause or involve notes in IEC 61326-1, they are numbered starting from 101
including those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
A list of all parts of IEC 61326 series, under the general title Electrical equipment for
measurement, control and laboratory use – EMC requirements can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

Part 2-5: Particular requirements –
Test configurations, operational conditions and performance criteria
for field devices with field bus interfaces according to IEC 61784-1

1 Scope
In addition to the requirements of IEC 61326-1, this part of IEC 61326 treats the particular
features for EMC testing of field devices with field bus interfaces. This part of IEC 61326 covers
only the field bus interface of the equipment.
NOTE The other functions of the equipment remain covered by other parts of IEC 61326 series.
This part refers only to field devices intended for use in process control and process measuring.
In this document, field devices with interfaces according to IEC 61784-1:2019, CP 3/2 and
CP 1/1 as defined in IEC 61784 are covered. Other field bus interfaces may be included in
future editions of this document.
IEC 61784-1:2019 specifies a set of protocol specific communication profiles based on
IEC 61158.
The manufacturer specifies the environment for which the product is intended to be used and/or
selects the appropriate test level specifications of IEC 61326-1.
