Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-033: Particular requirements for hand-held multimeters for domestic and professional use, capable of measuring mains voltage

IEC 61010-2-033:2019 is available as IEC 61010-2-033:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61010-2-033:2019 specifies safety requirements for hand-held multimeters for domestic and professional use, capable of measuring mains. Hand-held multimeters are multi-range multifunction measuring instruments intended to measure voltage and other electrical quantities such as resistance or current. Their primary purpose is to measure voltage on a live mains. They are suitable to be supported by one hand during normal use. This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - The scope has been reduced to hand-held multimeters. Voltmeters and clamp multimeters have been removed. They are addressed respectively by IEC 61010-2-030 and IEC 61010-2-032. The relevant definitions have been removed. - Subclause 4.4.2.101 has been relocated into Clause 102. - Clearances and creepage distances for wet locations and for measuring circuit terminals exceeding 1 000 V a.c. or 1 414 V d.c. have been specified. - Subclause 14.101 related to "Circuits or components used as transient overvoltage limiting devices in measuring circuits used to measure mains" has been removed. - References to IEC 61010-031 for probe assemblies and IEC 61010-2-032 for current sensors have been added. - Requirements for protection against mains overvoltage measuring circuits have been added. - Clause 102 has been rewritten. - Requirements for measuring circuits from 1 000 V to 3 000 V have been added. - An informative Annex CC about dimensions of 4-mm banana terminals has been added. - A flowchart for insulation according to the type of circuit has been added in a new Annex DD.

Exigences de sécurité pour appareils électriques de mesurage, de régulation et de laboratoire - Partie 2-033: Exigences particulières pour les multimètres portatifs pour usage domestique et professionnel, capables de mesurer la tension réseau

IEC 61010-2-033:2019 est disponible sous forme de IEC 61010-2-033:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 61010-2-033:2019 spécifie les exigences de sécurité applicables aux multimètres portatifs pour usage domestique et professionnel, capables de mesurer la tension réseau. Les multimètres portatifs sont des instruments de mesure multifonctions et avec plusieurs plages, destinés à mesurer la tension et d'autres grandeurs électriques telles que la résistance ou le courant. Ils ont pour objectif principal de mesurer la tension sur un réseau sous tension. Ils peuvent être tenus à la main en utilisation normale. Cette deuxième édition annule et remplace la première édition parue en 2012. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - Le domaine d'application a été réduit aux multimètres portatifs. Les voltmètres et les pinces multimétriques ont été supprimés. Ils sont traités respectivement par l'IEC 61010­2­030 et l'IEC 61010-2-032. Les définitions correspondantes ont été supprimées. - Le 4.4.2.101 a été intégré à l'Article 102. - Les distances d'isolement et les lignes de fuite applicables aux emplacements humides et aux bornes des circuits de mesure dont la tension alternative est supérieure à 1 000 V ou la tension continue est supérieure à 1 414 V ont été spécifiées. - Les exigences pour "Circuits ou composants utilisés comme limiteurs de surtensions dans les circuits de mesure utilisés sur un RESEAU" ont été supprimées. Le paragraphe 14.102 a été renuméroté 14.101. - Des références à l'IEC 61010-031 pour les sondes équipées et à l'IEC 61010-2-032 pour les capteurs de courant ont été ajoutées. - Des exigences relatives à la protection des circuits de mesure contre les surtensions du réseau ont été ajoutées. - L'Article 102 a été reformulé. - 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" de 4 mm 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 - 2-033. del: Posebne zahteve za ročne multimetre in druge merilnike za domačo in profesionalno uporabo, ki omogočajo merjenje omrežne napetosti (IEC 61010-2-033:2019)

Ta del standarda IEC 61010 določa varnostne zahteve za ročne multimetre za domačo in profesionalno uporabo, ki omogočajo merjenje v ELEKTRIČNEM OMREŽJU.
Ročni multimetri so večnamenski merilni instrumenti, namenjeni merjenju napetosti in drugih električnih veličin, kot sta upornost ali tok. Njihov primarni namen je merjenje napetosti v ELEKTRIČNEM OMREŽJU. Med OBIČAJNO UPORABO jih je mogoče držati z eno roko.
