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 61010-2-032:2023 specifies safety requirements for hand-held and hand-manipulated current sensors intended for measuring, detecting or injecting current, or indicating current waveforms on circuits without physically opening the current path of the circuit being measured.
These current sensors are hand-manipulated before and/or after a test or measurement, but are not necessarily hand-held during the test or measurement. They can be stand-alone current sensors or accessories to other equipment or parts of combined equipment. These include measurement circuits which are part of electrical test and measurement equipment, laboratory equipment, or process control equipment.
This fifth edition cancels and replaces the fourth edition published in 2019. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) In 1.1.1, definitions of current sensor types have been moved to a new Annex FF;
b) Clause 2, all normative references have been dated and new normative references have been added;

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
L'IEC 61010-2-032:2023 spécifie les exigences de sécurité pour les capteurs de courant portatifs et manipulés à la main 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.
Ces capteurs de courant sont manipulés manuellement avant et/ou après un essai ou un mesurage, mais il n’est pas nécessaire qu’ils soient portatifs pendant l’essai ou le mesurage. Les capteurs de courant peuvent être autonomes, ou accessoires d’autres appareils ou parties d’appareils combinés. 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.

INTERPRETATION SHEET 1
This interpretation sheet has been prepared by IEC technical committee 66: Safety of
measuring, control and laboratory equipment.
The text of this interpretation sheet is based on the following documents:
ISH Report on voting
66/497A/ISH 66/505/RVD
Full information on the voting for the approval of this interpretation sheet can be found in the
report on voting indicated in the above table.
___________
IEC 61010-1:2010 contains a requirement in 6.8.3.1 pertaining to voltage testers for type tests
as follows:
“The generator shall be able to supply a power of at least 500 VA.”
This has given rise to the following questions:
How does one interpret the requirement for voltage testers in 6.8.3.1 of IEC 61010-1:2010?
Specifically, this subclause requires that “The generator shall be able to supply a power of at
least 500 VA.” Does this requirement apply throughout the rated output range of the voltage
tester? What is meant by the word “generator”? Is the “generator” the power supply within the
voltage tester, or the voltage tester output, or something else?
Interpretation:
“A voltage tester used for type tests must be able to deliver at least 500 VA at its full-rated
output voltage. It does not necessarily need to deliver 500 VA if set for lower voltages.
For example, a voltage tester that can deliver 100 mA at any test output voltage up to 5 000 V
(and a current corresponding to 500 VA above 5 000 V) would meet the requirement.
The requirements for voltage testers used for routine (production line) tests are included in
Annex F. The requirements of 6.8.3.1 do not apply to these voltage testers.”
