IEC 61010-2-034:2023 specifies safety requirements to equipment for measuring insulation resistance and to equipment for testing electric strength which have an output voltage exceeding 50 V a.c. or 120 V d.c. This document also applies to combined measuring equipment which has an insulation resistance measurement function or an electric strength test measurement function. This document has the status of a horizontal publication in accordance with IEC Guide 108. It has the status of a group safety publication in accordance with IEC Guide 104. This second edition cancels and replaces the first edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) in 1.2.1, requirements for protection against hazards which could occur from reading a voltage have been added to the scope; b) Clause 2, all normative references have been dated; new normative references have been added; c) in 4.3.2.5, requirements for power supply have been modified; d) in 4.3.2.6, requirements for inputs/outputs have been modified; e) in 5.1.5.101.2, minimum ratings for voltage of measuring terminals are required; f) in 5.4.2, new ratings for documentation have been added; g) in 5.4.4, new instructions for operation have been added; h) in 5.101.1, hazard indicators shall be functional in normal condition and in single fault condition; i) in 6.6.101.1, insulating material of group I may be allowed for determination of creepage distances of measuring circuit terminals; j) in 6.6.101.2, Clearances and creepage distances above 1 000 V a.c. and 1 500 V d.c. for measuring circuit terminals in unmated position have been defined; k) in 6.6.101.3, requirements for measuring circuit terminals in partially mated position have been specified; l) in 6.6.101.4, requirements for measuring circuit terminals in mated position have been specified; m) Subclause 6.102 replaces 6.9.103 and has been rephrased; n) new Subclause 9.101 to consider the protection of measuring circuits against the spread of fire and arc flash has been added. Table 102 has been replaced by Table K.101; o) In 9.101.2, relocation of 101.3 of previous edition; p) In 9.101.3, relocation of 101.4 of previous edition, extension to measurement category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) in 9.101.4, requirements for measuring circuit terminals in mated position have been specified; r) in 9.101.5, relocation of K.103 of previous edition with numerous technical changes; s) in 14.101, relocation of 14.102. 14.101 of previous edition has been removed; t) in 101.3, relocation of 101.5 of previous edition, and more requirements added against hazard occurring from reading a voltage value; u) in K.2.1, another method for determination of clearances of secondary circuits is proposed; v) in K.3.2, new Table K.15 and Table K.16 for clearance calculation; w) in K.3.101, relocation of 6.9.104 of previous edition; x) in K.101.4.1, new Table K.103 and Table K.104 replace Table K.102, Table K.103 and Table K.104; y) in K.101.4, the subclause has been reviewed. Tables and tests for solid insulation have been modified. Table K.105 replaces Table K.9; z) Table K.101, replacement of Table K.106; aa) Clause K.4, redraft of the clause to propose a method for determination of Ut for circuits which reduce transient overvoltages; bb) Annex EE: addition of a new informative annex for determination of clearances for Table 101. LIEC 61010-2-034:2023 specifie les exigences de securite pour les appareils de mesure de la resistance d’isolement et les appareils d’essai de rigidite dielectrique avec une tension de sortie superieure a 50 V en courant alternatif ou 120 V en courant continu. Le present document s’applique egalement aux appareils de mesure combines equipes d’une fonction de mesure de la resistance d’isolement ou d’une fonction d’essai de rigidite dielectrique. Ce document a le statut dune publication horizontale conformement au Guide 108 de lIEC. Il a le statut d’une publication groupee de securite conformement au Guide IEC 104. Cette deuxieme edition annule et remplace la premiere edition parue en 2017. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: a) au paragraphe 1.2.1, les exigences relatives a la protection contre les dangers susceptibles de survenir lors de la lecture d’une tension ont ete ajoutees au domaine d’application; b) a l’Article 2, toutes les references normatives ont ete datees et de nouvelles references normatives ont ete ajoutees; c) au paragraphe 4.3.2.5, les exigences relatives a l’alimentation electrique ont ete modifiees; d) au paragraphe 4.3.2.6, les exigences relatives aux entrees/sorties ont ete modifiees; e) au paragraphe 5.1.5.101.2, des valeurs assignees minimales de tension des bornes des circuits de mesure sont exigees; f) au paragraphe 5.4.2, de nouvelles valeurs assignees pour la documentation ont ete ajoutees; g) au paragraphe 5.4.4, de nouvelles instructions de fonctionnement ont ete ajoutees; h) au paragraphe 5.101.1, les indicateurs de danger doivent etre fonctionnels en condition normale et en condition de premier defaut; i) au paragraphe 6.6.101.1, les materiaux isolants du groupe I peuvent etre admis pour la determination des lignes de fuite des bornes des circuits de mesure; j) au paragraphe 6.6.101.2, les distances d’isolement et les lignes de fuite superieures a 1 000 V en courant alternatif et a 1 500 V en courant continu pour les bornes des circuits de mesure en position decouplee ont ete definies; k) au paragraphe 6.6.101.3, les exigences relatives aux bornes des circuits de mesure en position partiellement couplee ont ete specifiees; l) au paragraphe 6.6.101.4, les exigences relatives aux bornes des circuits de mesure en position couplee ont ete specifiees; m) le paragraphe 6.102 remplace le paragraphe 6.9.
