This European Standard was approved by CENELEC on 2010-10-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat 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 Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus,
the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,
Spain, Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 66/417/FDIS, future edition 1 of IEC 61010-2-030, prepared by IEC TC 66, Safety
of measuring, control and laboratory equipment, was submitted to the IEC-CENELEC parallel vote and
was approved by CENELEC as EN 61010-2-030 on 2010-10-01.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2011-07-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2013-10-01
with the EN have to be withdrawn
This Part 2-030 is to be used in conjunction with the latest edition of EN 61010-1, Safety requirements for
electrical equipment for measurement, control and laboratory use - Part 1: General requirements. It was
established on the basis of the 2010 edition of EN 61010-1. Amendments and revisions of Part 1 have
also to be taken into account and the dates when such changes become applicable will be stated in the
relevant amendment or revision of Part 1.
This Part 2-030 supplements or modifies the corresponding clauses in EN 61010-1 so as to convert it into
the European Standard: Particular requirements for testing and measuring circuits.
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.
In the second edition of EN 61010-1, the requirements for testing and measuring circuits were included in
Part 1 itself. In the third edition of EN 61010-1, these requirements have been removed from Part 1 and
have become the basis for the requirements in this Part 2.
In addition to the requirements removed from Part 1, the following major requirements have been added
to this standard. Numerous other changes have also been made.
− The terminology for MEASUREMENT CATEGORY I has changed. In this Part 2, it is termed “not rated for
measurements within MEASUREMENT CATEGORIES II, III, or IV”.
− CLEARANCES and CREEPAGE DISTANCES have been added for unmated measuring circuit TERMINALS.
− Requirements have been added for specialized measuring circuit TERMINALS.
− Requirements for TRANSIENT OVERVOLTAGE limiting devices have been revised.
− Requirements have been revised and added pertaining to REASONABLY FORESEEABLE MISUSE of
measuring circuits, including disconnection of the protective earth and usage of the equipment in a
manner that might cause arc flash.
− Insulation requirements for measuring circuits have been primarily located in Annex K.
− Annex AA has been added to describe the characteristics of MEASUREMENT CATEGORIES.
− Annex BB has been added to describe hazards that may be encountered when using measuring
circuits.
NOTE 1 The following print types are used:
– requirements: in roman type;

– conformity and test: in italic type;
– NOTES: in small roman type;
– terms used throughout this standard which have been defined in Clause 3: SMALL ROMAN CAPITALS;
NOTE 2 Subclauses, figures, tables and notes which are additional to those in Part 1 are numbered starting from 101. Additional
Annexes are numbered AA and BB.
Annex ZA of Part 1 is applicable.

Part 2-030: Particular requirements for testing and measuring circuits

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 betw
