Electrical safety in low voltage distribution systems up to 1 000 V AC and 1 500 V DC - Equipment for testing, measuring or monitoring of protective measures - Part 1: General requirements
IEC 61557-1:2019 is available as IEC 61557-1:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61557-1:2019 specifies the general requirements applicable to measuring and monitoring equipment for testing the electrical safety in low-voltage distribution systems with nominal voltages up to 1 000 V AC and 1 500 V DC. When measuring equipment or measuring installations involve measurement tasks of various measuring equipment covered by this series of standards, then the part of this series relevant to each of the measurement tasks is applicable. Other parts of IEC 61557 can specify additional requirements or deviations. This document does not cover functional safety or cybersecurity. IEC 61557-1:2019 cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. This third edition includes the following significant technical changes with respect to the previous edition: a) terms aligned with IEC 60050; b) measurement of uncertainty revised according to the equations in 4.2 of ISO/IEC Guide 98-3:2008 (GUM); c) updated references for safety and EMC requirements; d) updated references for marking and operating instructions; e) updated references for testing safety and EMC; f) Annex A contains an explanation of GUM; g) Annex B addresses environmental aspects.

Lorsque des appareils ou installations de mesure impliquent des mesures avec différents appareils couverts par la présente série de normes, la partie de cette série de normes qui est pertinente pour un type de mesure donné est applicable. Les autres parties de l'IEC 61557 peuvent spécifier des exigences supplémentaires ou des écarts. La présente norme ne couvre pas la sécurité fonctionnelle ou la cybersécurité. L'IEC 61557-1:2019 annule et remplace la deuxième édition parue en 2007. Cette édition constitue une révision technique. Cette troisième édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) alignement des termes sur ceux de l'IEC 60050; b) mesure de l'incertitude revue conformément aux équations données en 4.2 du Guide ISO/IEC 98-3:2008 (GUM); c) mise à jour des références aux exigences de sécurité et de CEM; d) mise à jour des références au marquage et aux instructions de fonctionnement; e) mise à jour des références aux essais de sécurité et de CEM; f) l'Annexe A comporte une explication du GUM; g) l'Annexe B porte sur les aspects environnementaux.
Električna varnost v nizkonapetostnih razdelilnih sistemih za izmenične napetosti do 1 kV in enosmerne napetosti do 1,5 kV - Oprema za preskušanje, merjenje ali nadzorovanje zaščitnih ukrepov - 1. del: Splošne zahteve (IEC 61557-1:2019)
Ta del standarda IEC 61557 določa splošne zahteve, ki se uporabljajo za merilno in nadzorno opremo za preskušanje električne varnosti v nizkonapetostnih razdelilnih sistemih z nazivnimi napetostmi do 1000 V izmenične napetosti in 1500 V enosmerne napetosti.
Kadar merilna oprema ali merilne instalacije vključujejo merilna opravila različne merilne opreme, ki jo zajema ta serija standardov, se uporablja tisti del te serije, ki se navezuje na posamezno merilno opravilo.
OPOMBA: Izraz »merilna oprema« se bo v nadaljevanju uporabljal za »opremo za preskušanje, merjenje in nadzorovanje«.
Drugi deli standarda IEC 61557 lahko določajo dodatne zahteve ali odstopanja. Ta dokument ne zajema funkcionalne ali kibernetske varnosti.
