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.
This International Standard IEC 61326-2-3 has been prepared by subcommittee 65A: System
aspects, of IEC technical committee 65: Industrial-process measurement, control and
automation.
This second edition cancels and replaces the first edition published in 2006. This edition
constitutes a technical revision.
This edition includes the following significant technical change with respect to the previous
edition:
– update of the document with respect to IEC 61326-1:2012.

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This part of the IEC 61326 series is to be used in conjunction with IEC 61326-1:2012 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 the IEC 61326 series, under the general title Electrical equipment for
measurement, control and laboratory use, control and laboratory use – EMC requirements,
can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

Part 2-3: Particular requirements –
Test configuration, operational conditions and performance
criteria for transducers with integrated or remote signal conditioning

1 Scope
In addition to the requirements of IEC 61326-1, this part specifies more detailed test
configurations, operational conditions and performance criteria for transducers with integrated
or remote signal conditioning.
This standard applies only to transducers characterized by their ability to transform, with the
aid of an auxiliary energy source, a non-electric quantity to a process-relevant electrical
signal, and to output the signal at one or more ports. This standard includes transducers for
electrochemical and biological measured quantities.
The transducers covered by this standard may be powered by a.c. or d.c. voltage and/or by
battery or with internal power supply.
Transducers referred to by this standard comprise at least the following items (see
Figures 101 and 102):
– one or more elements for transforming a non-electrical input quantity to an electrical
quantity;
– a transmission link for transferral of the electrical quantity to a component for signal
conditioning;
– a unit for signal conditioning that converts the electrical quantity to a process-relevant
electrical signal;
– an enclosure for enclosing the above-stated components fully or in parts.
Transducers referred to by this standard may also have the following items (see Figures 101
and 102):
– a communication and control unit;
– a display unit;
– control elements such as keys, buttons, switches, etc.;
– transducer output signals (for example, switch outputs, alarm outputs) which are clearly
assigned to the input signal(s);
– transducers with signal conditioning which may be integrated or remote.
The manufacturer specifies the environment for which the product is intended to be used and
utilizes the corresponding test levels of IEC 61326-1.
Additional requirements and exceptions for specific types of transducers are given in the
annexes to this standard.
