IEC 61010-2-032:2019

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 is available as IEC 61010-2-032:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61010-2-032:2019 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. 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:
- It has been indicated that current sensors used as fixed equipment are not within the scope of this document.
- Fork-style current sensors have been added.
- Requirements from Part 2-033 applicable to clamp multimeters that have a primary purpose of measuring voltage on live mains have been included in the new normative Annex EE.
- Clearances and creepage distances for measuring circuit terminals exceeding 1 000 V a.c. or 1 414 V d.c. and for wet locations have been specified.
- Reduced creepage distances are allowed to be according to material group I for all insulating materials.
- Requirements for input/output circuits of Type A, Type B and Type C current sensors have been detailed in 6.9.102.
- Requirements for output circuit leads have been modified.
- The Jaw impact test has been limited to the front of the jaws.
- The abrasion test for cords of flexible current sensors has been removed and replaced by a pressure test at high temperature.
- The voltage source for testing overvoltage limiting components or circuits may be limited to 400 V.
- Reference to IEC 61010-031 for probe assemblies has been added.
- Requirements for the prevention of transient overvoltages for mains voltage measuring circuits have been added.
- Requirements for measuring circuits from 1 000 V to 3 000 V have been added.
- An informative Annex CC about the dimensions of banana terminals has been added.
- A flowchart for insulation according to the type of circuit has been added in a new Annex DD.
The contents of the corrigendum of February 2020 have been included in this copy.

Exigences de sécurité pour appareils électriques de mesurage, de régulation et de laboratoire - Partie 2-032 : Exigences particulières pour les capteurs de courant, portatifs et manipulés manuellement, pour essai électrique et mesurage

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.

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.
