IEC 61010-2-032:2023 EXV
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 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with the comprehensive content of the Standard. IEC 61010-2-032:2023 EXV includes the content of the references made to IEC 61010-1:2010 and IEC 61010-1:2010/AMD1:2016.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;c) 3.2.103, a new definition protective fingerguard has been added which replaces the previous definition of protective barrier;d) 4.4.2.101 is a new subclause about surge protective devices;e) in 5.1.5.101.2, minimum ratings for voltage of measuring terminals are required;f) Subclause 6.5.1 has been modified;g) Subclause 6.5.5 is no longer used;h) Subclause 6.6.101 modifies 6.6.101 and 6.6.102 of previous edition:1) in 6.6.101.1, insulating material of group I may be allowed for determination of creepage distances of measuring circuit terminals;2) in 6.6.101.2, clearances and creepage distances up to 3 000 V for measuring circuit terminals in unmated position have been defined;3) in 6.6.101.3, requirements for measuring circuit terminals in partially mated position have been specified;4) in 6.6.101.4, requirements for measuring circuit terminals in mated position have been specified;5) Subclause 6.6.101.5 replaces 6.6.102;i) Subclause 6.6.102 replaces 6.101 of previous edition with modifications;j) Subclause 6.101.2 replaces 6.9.101.1 of previous edition with modifications;k) Subclause 6.101.3 replaces 6.9.101.2 of previous edition with modifications;l) Subclause 6.101.4 replaces 6.9.102 of previous edition with modifications;m) in 8.101, jaw ends abrasion test has been modified;n) 8.105 is a new subclause for input/output leads attachment has been added;o) in 9.101.2, relocation of 101.3 of previous edition;p) in 9.101.3, relocation of 101.4 of previous edition, extension to measurement category II and reference to IEC 61000-4-5 for tests:q) Table 104 has been replaced by Table K.101:r) in 9.102, relocation of Clause 102 of previous edition;s) in 14.101, relocation of 14.102.

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. Le contenu du corrigendum de février 2020 a été pris en considération dans cet exemplaire.
