Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-034: Particular requirements for measurement equipment for insulation resistance and test equipment for electric strength

Asnjë informacion i shtuar.

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 Table 102 has been replaced by Table K.101; o) In 9.101.2, relocation of 101.3 of previous edition; p) In 9.101.3, relocation of 101.4 of previous edition, extension to measurement category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: addit
