SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT

FOR MEASUREMENT, CONTROL, AND LABORATORY USE –

Part 3-032: Conformity verification report for IEC 61010-2-032:1994,

Particular requirements for hand-held current clamps

for electrical measurement and test

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
Technical reports do not necessarily have to be reviewed until the data they provide are
considered to be no longer valid or useful by the maintenance team.

IEC 61010-3-032, which is a technical report, has been prepared by IEC technical
committee 66: Safety of measuring, control, and laboratory equipment.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
66/192/CDV 66/216/RVC
Full information on the voting for the approval of this technical report can be found in the report
on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.

– 4 – TR 61010-3-032  IEC:2000(E)

This report is a Technical Report and is of a purely informative nature and is therefore by itself

not to be regarded as an International Standard. It is for use by testhouses and other users to

assist them with determining and recording verification of conformity of the equipment under

test with the requirements of
IEC 61010-2-032:1997,
and
IEC 61010-1:1990 + amendment 1:1992

or
IEC 61010-1:1990 + amendment 1:1992 + amendment 2:1995

The protocol for completion of this report is contained in publication IEC 61010-3:1997.
Requirements which apply only to amendment 2 to IEC 61010-1 are indicated by “(AM 2)” in
the first column. Requirements deleted by amendment 2 to IEC 61010-1 are indicated by
“(AM 1 only)” in the second column.
Reference to IEC 61010-1 clauses and subclauses which have no applicability for
IEC 61010-2-032 have been identified in the comments column of the report as ‘Not
applicable’. The Forms A.9, A.21, A.22, A.23, A.25, A.26, A.27 and A.28, which are normally
associated with these clauses/subclauses, are also excluded from this report.
The IEC sells read-only PDF files as a general rule. In the present instance, and quite
exceptionally, to enable the user to fill in the forms, a revisable file is included in a pocket
affixed to the back cover of this publication.
This publication can be downloaded from the Web as a PDF file. There is, however, at the end
of the document, a revisable file containing the forms. Please use the zip/unzip function.
