measuring MAINS voltage
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 redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

International Standard IEC 61010-2-033 has been prepared by IEC technical committee 66:
Safety of measuring, control and laboratory equipment.

This second edition cancels and replaces the first edition published in 2012. This edition
constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous
edition:
a) The scope has been reduced to hand-held multimeters. Voltmeters and clamp multimeters

have been removed. They are addressed respectively by IEC 61010-2-030 and

IEC 61010-2-032. The relevant definitions have been removed.
b) Subclause 4.4.2.101 has been relocated into Clause 102.
c) CLEARANCES and CREEPAGE DISTANCES for WET LOCATIONS and for measuring circuit
TERMINALS exceeding 1 000 V a.c. or 1 414 V d.c. have been specified.
d) Subclause 14.101 related to "Circuits or components used as TRANSIENT OVERVOLTAGE
limiting devices in measuring circuits used to measure MAINS" has been removed.
e) References to IEC 61010-031 for probe assemblies and IEC 61010-2-032 for current
sensors have been added.
f) Requirements for protection against MAINS overvoltage measuring circuits have been
added.
g) Clause 102 has been rewritten.
h) Requirements for measuring circuits from 1 000 V to 3 000 V have been added.
