SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL, AND LABORATORY USE –
Part 2-034: Particular requirements for measurement equipment
for insulation resistance and test equipment for electric strength
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.
IEC 61010-2-034 has been prepared by IEC technical committee 66: Safety of measuring,
control and laboratory equipment. It is an International Standard.
It has the status of a group safety publication in accordance with IEC Guide 104.
This second edition cancels and replaces the first edition published in 2017. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) in 1.2.1, requirements for protection against HAZARDS which could occur from reading a
voltage have been added to the scope;
b) Clause 2, all normative references have been dated; new normative references have been
added;

INTRODUCTION
IEC 61010-1 specifies the safety requirements that are generally applicable to all equipment
within its scope. For certain types of equipment, the requirements of IEC 61010-1 and its
amendment will be supplemented or modified by the special requirements of one or more
standard from the IEC 61010-2 series which is/are read in conjunction with the requirements of
IEC 61010-1.
1) IEC 61010-2-030 specifies the safety requirements for equipment with testing or measuring
circuits which are connected for test or measurement purposes to devices or circuits outside
the measurement equipment itself.
2) IEC 61010-2-032 specifies the safety requirements for hand-held and hand-manipulated
current sensors for measuring, detecting or injecting current, or indicating current
waveforms on circuits without physically opening the current path of the circuit being
measured.
Most of the requirements of IEC 61010-2-030 have been included in
IEC 61010-2-032. Equipment within the scopes of both IEC 61010-2-030 and IEC 61010-2-
032 are considered to be covered by the requirements of IEC 61010-2-032.
However, for current sensors in combined equipment with protective bonding and automatic
disconnection of the supply, IEC 61010-2-030 and IEC 61010-2-032 are read in conjunction.
3) IEC 61010-2-033 specifies the safety requirements for hand-held multimeters and other
meters for domestic and professional use, capable of measuring mains voltage, intended to
measure voltage and other electrical quantities such as resistance or current.
All relevant requirements of IEC 61010-2-030 have been included in
IEC 61010-2-033.
4) This document specifies the safety requirements for measurement equipment for insulation
resistance and test equipment for electric strength which are connected to units, lines or
circuits for test or measurement purposes.
All relevant requirements of IEC 61010-2-030 have been included in this document.
However, for equipment within the scope of IEC 61010-2-032 and of this document, these
standards are read in conjunction.
IEC 61010-031 specifies the safety requirements for hand-held and hand-manipulated probe
assemblies and their related accessories intended to be used in particular with equipment in
the scope of IEC 61010-2-030, IEC 61010-2-032, IEC 61010-2-033 and this document. These
probe assemblies are for non-contact or direct electrical connection between a part and
electrical test and measurement equipment. They may be fixed to the equipment or be
detachable accessories for the equipment.

for insulation resistance and test equipment for electric strength
1 Scope and object
IEC 61010-1:2010, Clause 1 and IEC 61010-1:2010/AMD1:2016, Clause 1 apply except as
follows:
1.1.1 Equipment included in scope
Replace the existing text with the following:
This document specifies safety requirements to equipment for measuring insulation resistance
and to equipment for testing electric strength which have an output voltage exceeding 50 V a.c.
or 120 V d.c.
This document also applies to combined measuring equipment which has an insulation
resistance measurement function or an electric strength test measurement function.
This group safety publication focusing on safety essential requirements is primarily intended to
be used as a product safety standard for the products mentioned in the scope, but is also
intended to be used by technical committees in the preparation of publications for products
similar to those mentioned in the scope of this document, in accordance with the principles laid
down in IEC Guide 104 and lSO/lEC Guide 51.
One of the responsibilities of a technical committee is, wherever applicable, to make use of
basic safety publications and/or group safety publications in the preparation of its publications.
1.1.2 Equipment excluded from scope
Add the following new items to the list:
aa) IEC 61557-8 (Electrical safety in low voltage distribution systems up to 1 000 V a.c. and
1 500 V d.c. – Equipment for testing, measuring or monitoring of protective measures –
Part 8: Insulation monitoring devices for IT systems);
bb) IEC 61557-9 (Electrical safety in low voltage distribution systems up to 1 000 V a.c. and
1 500 V d.c. – Equipment for testing, measuring or monitoring of protective measures –
Part 9: Equipment for insulation fault location in IT systems).
1.2.1 Aspects included in scope
Replace item c) of the second paragraph with the following new item c):
c) spread of fire or arc flash from the equipment (see Clause 9);
Replace the third paragraph with the following two new paragraphs:
HAZARDS arising from NORMAL USE, REASONABLY
Requirements for protection against
FORESEEABLE MISUSE and ergonomic factors are specified in Clause 16 and Clause 101.
