(Main)Safety requirements for electrical equipment for measurement, control and laboratory use - Part 2-032: Particular requirements for hand-held and hand-manipulated current sensors for electrical test and measurement (IEC 61010-2-032:2019 + COR1:2020)
Safety requirements for electrical equipment for measurement, control and laboratory use - Part 2-032: Particular requirements for hand-held and hand-manipulated current sensors for electrical test and measurement (IEC 61010-2-032:2019 + COR1:2020)
This part of IEC 61010 specifies safety requirements for HAND-HELD and hand-manipulated
current sensors described below.
These current sensors are for measuring, detecting or injecting current, or indicating current
waveforms on circuits without physically opening the current path of the circuit being
measured. They can be stand-alone current sensors or accessories to other equipment or
parts of combined equipment (see Figure 101). These include measurement circuits which are
part of electrical test and measurement equipment, laboratory equipment, or process control
equipment. These current sensors and circuits need additional protective means between the
current sensor, the circuit and an OPERATOR.
NOTE 1 Combined equipment is equipment that is electrically connected to a current sensor by means of a
permanent connection which can be detached only by the use of a TOOL.
NOTE 2 Some current sensors are also known as current clamps, CLAMP MULTIMETERS and current probes.
Current sensors are hand-manipulated before and/or after a test or measurement, but do not
necessarily need to be HAND-HELD during the test or measurement. Current sensors used as
FIXED EQUIPMENT are not within the scope of this document.

IEC 61010-2-032:2019 est disponible sous forme de IEC 61010-2-032:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L'IEC 61010-2-032:2019 spécifie les exigences de sécurité pour les capteurs de courant portatifs et manipulés manuellement décrits ci-dessous. Ces capteurs de courant sont conçus pour mesurer, détecter ou injecter du courant, ou afficher les formes d'onde du courant sur les circuits sans ouverture physique du chemin du courant sur le circuit mesuré. Les capteurs de courant peuvent être autonomes, ou accessoires d'autres appareils ou parties d'appareils combinés (voir la Figure 101). Cela comprend les circuits de mesure qui font partie des appareils électriques d'essai et de mesure, du matériel de laboratoire ou des appareils de contrôle de procédés industriels. Ces capteurs de courant et circuits nécessitent des moyens de protection supplémentaires entre le capteur de courant, le circuit et un opérateur. Cette quatrième édition annule et remplace la troisième édition parue en 2012. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Il est indiqué que les capteurs de courant utilisés comme appareils installés à poste fixe ne relèvent pas du domaine d'application du présent document.
- Les capteurs de courant à fourche ont été ajoutés.
- Les exigences de la Partie 2-033 applicables aux pinces multimétriques qui ont pour objectif principal de mesurer la tension sur des réseaux sous tension ont été incluses dans la nouvelle Annexe EE normative.
- Les distances d'isolement et les lignes de fuite applicables aux emplacements humides et aux bornes d'un circuit de mesure dont la tension alternative est supérieure à 1 000 V ou dont la tension continue est supérieure à 1 414 V ont été spécifiées.
- Il est admis d'utiliser les lignes de fuite conformes au groupe de matériaux I pour tous les matériaux isolants.
- Les exigences relatives aux circuits d'entrée/sortie des capteurs de courant de Type A, de Type B et de Type C ont été détaillées en 6.9.102.
- Les exigences relatives aux cordons des circuits de sortie ont été modifiées.
- L'essai de choc de la mâchoire a été limité à la partie avant des mâchoires.
- L'essai d'abrasion des cordons de capteurs de courant flexibles a été supprimé et remplacé par un essai de pression à haute température.
- La source de tension utilisée pour l'essai des composants ou des circuits de limitation des surtensions peut être limitée à 400 V.
- Une référence à l'IEC 61010-031 pour les sondes équipées a été ajoutée.
- Des exigences permettant d'éviter les surtensions transitoires applicables aux circuits de mesure de tension de réseau ont été ajoutées.
- Des exigences concernant les circuits de mesure entre 1 000 V et 3 000 V ont été ajoutées.
- Une Annexe CC informative relative aux dimensions des bornes "banane" a été ajoutée.
- Un organigramme de l'isolation selon le type de circuit a été ajouté dans une nouvelle Annexe DD.
Varnostne zahteve za električno opremo za meritve, nadzor in laboratorijsko uporabo - 2-032. del: Posebne zahteve za ročne in ročno vodene tokovne senzorje za električno preskušanje in meritve (IEC 61010-2-032:2019 + COR1:2020)
Ta del standarda IEC 61010 določa varnostne zahteve za spodaj navedene ROČNE in ročno vodene tokovne senzorje. Ti tokovni senzorji so namenjeni za merjenje, zaznavanje ali priključitev toka ali določanje oblik toka na tokokrogih, ne da bi bilo treba fizično odpreti tokovne poti tokokroga, na katerem se izvaja meritev. Tokovni senzorji so lahko samostojni ali priključki k drugi opremi ali delom sestavljene opreme (glej sliko 101). Zajemajo merilne tokokroge, ki so del električne preskusne in merilne opreme, laboratorijske opreme ali opreme za vodenje procesa. Pri teh tokovnih senzorjih in tokokrogih je potrebno dodatno zaščitno sredstvo med tokovnim senzorjem, tokokrogom in UPRAVLJAVCEM. OPOMBA 1: Sestavljena oprema je oprema, ki je električno povezana s tokovnim senzorjem prek trajnega priključka, ki ga je mogoče odstraniti samo z ORODJEM. OPOMBA 2: Nekateri tokovni senzorji se imenujejo tudi tokovne klešče, KLEŠČNI MULTIMETRI in tokovne sonde. Tokovne senzorje je treba pred preskusom oziroma meritvijo in/ali po tem upravljati ročno, vendar jih med preskusom oziroma meritvijo ni vedno treba DRŽATI V ROKI. Tokovni senzorji, ki se uporabljajo kot FIKSNA OPREMA, ne spadajo na področje uporabe tega dokumenta.

SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL, AND LABORATORY USE –
Part 2-032: Particular requirements for HAND-HELD and
hand-manipulated current sensors for electrical test and measurement
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 61010-2-032 has been prepared by IEC technical committee 66:
Safety of measuring, control and laboratory equipment.
This fourth edition cancels and replaces the third 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) It has been indicated that current sensors used as FIXED EQUIPMENT are not within the

1.1.1 Equipment included in scope
Replace the existing text with the following:
HAND-HELD and hand-manipulated
This part of IEC 61010 specifies safety requirements for
current sensors described below.
These current sensors are for measuring, detecting or injecting current, or indicating current
waveforms on circuits without physically opening the current path of the circuit being
measured. They can be stand-alone current sensors or accessories to other equipment or
parts of combined equipment (see Figure 101). These include measurement circuits which are
part of electrical test and measurement equipment, laboratory equipment, or process control
equipment. These current sensors and circuits need additional protective means between the
current sensor, the circuit and an OPERATOR.
NOTE 1 Combined equipment is equipment that is electrically connected to a current sensor by means of a
permanent connection which can be detached only by the use of a TOOL.
NOTE 2 Some current sensors are also known as current clamps, CLAMP MULTIMETERS and current probes.
Current sensors are hand-manipulated before and/or after a test or measurement, but do not
necessarily need to be HAND-HELD during the test or measurement. Current sensors used as
FIXED EQUIPMENT are not within the scope of this document.
The following types of current sensors are covered:
a) Type A: a current sensor designed to be applied to or removed from HAZARDOUS LIVE
UNINSULATED CONDUCTORS. Type A current sensors have defined HAND-HELD or hand-
manipulated parts providing protection against electric shock from the conductor being
measured, and also have protection against short-circuits between wires and between
busbars during clamping.
b) Type B: a current sensor which has protection against short-circuits between wires or
busbars during clamping but without defined HAND-HELD or hand-manipulated parts which
provide protection against electric shock during clamping. Additional protective means are
necessary to avoid electric shock from HAZARDOUS LIVE conductors which cannot be de-
energised during application or removal of the current sensor.
EXAMPLE 1 Flexible current sensors.
c) Type C: a current sensor without protection against short-circuits between wires or
busbars during clamping. Type C current sensors are intended to be applied to or
removed from HAZARDOUS LIVE UNINSULATED CONDUCTORS or from non-limited-energy
circuit conductors only when they are de-energised.
EXAMPLE 2 Split-core transducers.
d) Type D: a current sensor designed to be applied to or removed from insulated conductors
or from limited-energy circuit conductors.

EXAMPLE 3 Current probes for oscilloscopes and earth leakage current detectors.
All current sensors can also be used with insulated conductors. In this case, HAZARDS are
limited to acceptable levels by the insulation of the conductors.
Additional requirements for CLAMP MULTIMETERS are given in Annex EE.
Figure 101 shows graphical representations of typical current sensors for illustration
purposes. Current sensors can look different depending on the design.
