标准摘要
[中文适用范围]： 本文件规定了适用于家用和专业用手持式万用表及其他能够测量市电电压的仪表的安全要求。手持式万用表是多量程多功能测量仪器，旨在测量电压以及其他电气量（如电阻或电流）。其主要用途是测量带电市电上的电压。它们适合在正常使用期间单手支撑。 [外文原描述]： IEC 61010-2-033:2023 specifies safety requirements for hand-held multimeters and other meters 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 third edition cancels and replaces the second edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Clause 2, all normative references have been dated and new normative references have been added; b) 4.4.2.101 is a new subclause about surge protective devices; c) Subclause 6.6.101 modifies 6.6.101 and 6.6.102 of previous edition: 1) in 6.6.101.1, insulating material of group I may be allowed for determination of creepage distances of measuring circuit terminals; 2) in 6.6.101.2, Clearances and creepage distances up to 3 000 V for measuring circuit terminals in unmated position have been defined; 3) in 6.6.101.3, requirements for measuring circuit terminals in partially mated position have been specified; 4) in 6.6.101.4, requirements for measuring circuit terminals in mated position have been specified; 5) Subclause 6.6.101.5 replaces 6.6.102; d) Subclause 6.101 replaces 6.9.101 of the previous edition with modifications; e) 9.101 is a new subclause to consider the protection of measuring circuits against the spread of fire and arc flash; f) in 9.101.2, relocation of 101.3 of previous edition; g) in 9.101.3, relocation of 101.4 of previous edition; h) in 101.3, relocation of Clause 102 of previous edition; i) in K.2.1, another method for determination of clearances of secondary circuits is proposed; j) in K.3.2, new Table K.15 and Table K.16 for clearance calculation; k) Clause K.4 of the previous edition has been deleted; l) Subclause K.101.4 has been reviewed; m) Table K.104 of the previous edition has been deleted; n) Annex AA: Figure AA.1 has been redesigned; o) Annex EE: addition of a new informative annex for determination of clearances for the purposes of Table 101.
