Part 1: General requirements


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 61326-1 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 2005. This edition
constitutes a technical revision.
The significant technical changes with respect to the previous edition are as follows:
– the immunity test levels and performance criteria have been reviewed;
– requirements for portable test and measurement equipment have been clarified and
amended;
– the description of the electromagnetic environments has been improved.

INTRODUCTION
Instruments and equipment within the scope of this standard may often be geographically
widespread and hence operate under a wide range of environmental conditions.
The limitation of undesired electromagnetic emissions ensures that no other equipment,
installed nearby, is unduly influenced by the equipment under consideration. The limits are
more or less specified by, and therefore taken from, IEC and International Special Committee
on Radio Interference (CISPR) publications.
However, the equipment should function without undue degradation in an electromagnetic
environment typical for the locations where it is intended to be operated. In this respect the
standard specifies three different types of electromagnetic environment and the levels for
immunity. More detailed information about issues related to electromagnetic environments are
given in IEC 61000-2-5. Special risks, involving for example nearby or direct lightning strikes,
circuit-breaking, or exceptionally high electromagnetic radiation in close proximity, are not
covered.
Complex electric and/or electronic systems should require EMC planning in all phases of their
design and installation, taking into consideration the electromagnetic environment, any
special requirements, and the severity of failures.
This part of IEC 61326 specifies the EMC requirements that are generally applicable to all
equipment within its scope. For certain types of equipment, these requirements will be
supplemented or modified by the special requirements of one, or more than one, particular
part within IEC 61326-2 series. These should be read in conjunction with the IEC 61326-1
requirements.

ELECTRICAL EQUIPMENT FOR MEASUREMENT,
CONTROL AND LABORATORY USE –
EMC REQUIREMENTS –

Part 1: General requirements



1 Scope
This part of IEC 61326 specifies requirements for immunity and emissions regarding electro-
magnetic compatibility (EMC) for electrical equipment, operating from a supply or battery of
less than 1 000 V a.c. or 1 500 V d.c. or from the circuit being measured. Equipment intended
for professional, industrial-process, industrial-manufacturing and educational use is covered
by this part. It includes equipment and computing devices for
– measurement and test;
– control;
– laboratory use;
– accessories intended for use with the above (such as sample handling equipment),
intended to be used in industrial and non-industrial locations.
Computing devices and assemblies and similar equipment within the scope of Information
Technology Equipment (ITE) and complying with applicable ITE EMC standards may be used
in systems within the scope of this part of IEC 61326 without additional testing, if they are
suitable for the intended electromagnetic environment.
It is generally considered that this standard takes precedence over the corresponding generic
EMC standards.
The following equipment is covered by this standard.
a) Electrical measurement and test equipment
This is equipment which, by electrical means, measures, indicates or records one or more
electrical or non-electrical quantities, also non-measuring equipment such as signal
generators, measurement standards, power supplies and transducers.
b) Electrical control equipment
This is equipment which controls one or more output quantities to specific values, with
each value determined by manual settings, by local or remote programming, or by one or
more input variables. This includes Industrial Process Measurement and Control (IPMC)
equipment, which consists of devices such as:
– process controllers and regulators;
– programmable controllers;
– power supply units for equipment and systems (centralized or dedicated);
– analogue/digital indicators and recorders;
– process instrumentation;
– transducers, positioners, intelligent actuators, etc.

---------------------- Page: 15 ----------------------

SIST EN 61326-1:2013
– 8 – 61326-1 © IEC:2012
c) Electrical laboratory equipment
This is equipment which measures, indicates monitors or analyses substances, or is used
to prepare materials, and includes In Vitro Diagnostic (IVD) equipment. This equipment
may also be used in areas other than laboratories, for example self-test IVD equipment
may be used in the home.
Equipment within the scope of this standard might be operated in different electromagnetic
environments; depending on the electromagnetic environment different emission and immunity
test requirements are applicable.
This standard considers three types of electromagnetic environments:
• basic electromagnetic environment;
• industrial electromagnetic environment;
• controlled electromagnetic environment.
Corresponding immunity test requirements are described in Clause 6.
In terms of emission requirements, equipment shall be classified in Class A or Class B
equipment, as per the requirements and procedure of CISPR 11. The corresponding emission
requirements are described in Clause 7.
