application to the CEN-CENELEC Management Centre or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the CEN-CENELEC Management Centre has the same status as the official versions.

Foreword
The text of document 65/515/FDIS, future edition 1 of IEC 61010-2-201, prepared by IEC TC 65
"Industrial-process measurement, control and automation" was submitted to the IEC-CENELEC parallel
vote and approved by CENELEC as EN 61010-2-201:2013.
The following dates are fixed:
• latest date by which the document has (dop) 2014-01-01
to be implemented at national level by
publication of an identical national
standard or by endorsement
(dow) 2016-04-01
• latest date by which the national
standards conflicting with the

document have to be withdrawn

This document partially supersedes EN 61131-2:2007.
This Part 2-201 is intended to be used in conjunction with EN 61010-1:2010. Consideration may be given
to future editions of, or amendments to, EN 61010-1.
This Part 2-201 supplements or modifies the corresponding clauses in EN 61010-1 so as to convert that
publication into the European standard: Particular requirements for control equipment.
Where a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is
reasonable. Where this part states “addition”, “modification”, “replacement”, or “deletion”, the relevant
requirement, test specification or note in Part 1 should be adapted accordingly.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent
rights.
This standard covers the Principle Elements of the Safety Objectives for Electrical Equipment Designed
for Use within Certain Voltage Limits (LVD - 2006/95/EC).

Endorsement notice

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

Part 2-201: Particular requirements for control equipment


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 61010-2-201 has been prepared by IEC technical committee 65:
Industrial-process measurement, control and automation.
The text of this standard is based on the following documents:
FDIS Report on voting
65/515/FDIS 65/521/RVD

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 Part 2-201 is intended to be used in conjunction with IEC 61010-1. It was established on
the basis of the third edition (2010). Consideration may be given to future editions of, or
amendments to, IEC 61010-1.

This Part 2-201 supplements or modifies the corresponding clauses in IEC 61010-1 so as to
convert that publication into the IEC standard: Particular requirements for control equipment.
Where a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. Where this part states “addition”, “modification”, “replacement”, or
“deletion”, the relevant requirement, test specification or note in Part 1 should be adapted
accordingly.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
It has the status of a basic safety publication in accordance with IEC Guide 104.
A list of all parts in the IEC 61010 series, published under the general title Safety
requirements for electrical equipment for measurement, control and laboratory use, 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.
