Annotation of standard text IEC 61557-1-ed.3.0 :
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. LIEC 61557-1:2019 specifie les exigences generales applicables aux dispositifs de mesure et de surveillance utilises aux fins dessai de la securite electrique dans les reseaux de distribution basse tension au plus egale a 1 000 V c.a. et 1 500 V c.c. Lorsque des appareils ou installations de mesure impliquent des mesures avec differents appareils couverts par la presente serie de normes, la partie de cette serie de normes qui est pertinente pour un type de mesure donne est applicable. Les autres parties de lIEC 61557 peuvent specifier des exigences supplementaires ou des ecarts. La presente norme ne couvre pas la securite fonctionnelle ou la cybersecurite. LIEC 61557-1:2019 annule et remplace la deuxieme edition parue en 2007. Cette edition constitue une revision technique. Cette troisieme edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) alignement des termes sur ceux de lIEC 60050; b) mesure de lincertitude revue conformement aux equations donnees en 4.2 du Guide ISO/IEC 98-3:2008 (GUM); c) mise a jour des references aux exigences de securite et de CEM; d) mise a jour des references au marquage et aux instructions de fonctionnement; e) mise a jour des references aux essais de securite et de CEM; f) lAnnexe A comporte une explication du GUM; g) lAnnexe B porte sur les aspects environnementaux.
