测量、控制和实验室用电气设备的安全要求.第031部分:电气试验和测量用手持式和手动探头组件的安全要求

[中文适用范围]： 本部分 IEC 61010 规定了用于电气测试和测量的手持和手操纵探头组件及其相关附件的安全要求。这些探头组件用于非接触或直接电气连接部件与电气测试和测量设备之间。它们可以固定在设备上或作为设备的可拆卸附件。该组安全出版物主要用作范围内产品的产品安全标准，但也旨在供技术委员会根据 IEC 指南 104 和 ISO/IEC 指南 51 中规定的原则，在编制与组安全出版物范围内产品类似的出版物时使用。技术委员会的职责之一是在适用的情况下，在其出版物编制过程中使用基本安全出版物和/或组安全出版物。 [外文原描述]： IEC 61010-031:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61010-031:2022 edition 3.0 and the previous IEC 61010-031:2015+AMD1:2018 CSV edition 2.1. Furthermore, comments from IEC TC 66 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 61010-031:2022 specifies safety requirements for hand-held and hand-manipulated probe assemblies for electrical test and measurement, and their related accessories. These probe assemblies are for non-contact or direct electrical connection between a part and electrical test and measurement equipment. They can be fixed to the equipment or be detachable accessories for the equipment. It has the status of a group safety publication in accordance with IEC Guide 104. This third edition cancels and replaces the second edition published in 2015, and Amendment 1:2018. IEC 61010-031 is a stand-alone standard. This edition includes the following significant technical changes with respect to the previous edition: the scope has been made succinct. General information from the scope of Edition 2 has been moved to a new Clause 4. Consequently, Clause 4 to Clause 8 of Edition 2 have been renumbered. Clause 9 of Edition 2 has been deleted; in Clause 2, normative references have been dated and new normative references have been added; in 3.1.4, the definition of probe tip has been modified; in 4.1, there is no longer any differentiation between high voltage and low voltage probe assemblies. Type C probe assemblies have been merged with Type B probe assemblies; in 4.1 d) "Kelvin" probes have been added to the list of probe assemblies as a new Type E and a new Figure 5; in 4.1 e), probes for voltage measurement without electrical connection to conductors have been added to the list of probe assemblies as a new Type F and a new Figure 6; in 4.2.1, spread of fire is no longer considered as a hazard; Subclause 4.4.2.5 from Edition 2 has been deleted; Subclause 4.4.4.3 from Edition 2 has been deleted; in 5.4.4.1 consideration has been given to spacings and impedance; in 6.1.1, removable parts of probe tips which bear markings are allowed; in 6.1.5, the voltage to be marked for measurement categories is the AC line-to-neutral or DC voltage; in 7.4.2, requirements for unmated connectors have been modified as follows: Table 2 has been modified and expanded, a calculation method for clearances of connectors above 20 kV has been defined, creepage distances have been aligned with clearances; in 7.4.3.1 and 7.4.3.5, requirements for IP2X probe tips with retractable sleeve have been added; in 7.4.3.2, Probe tips are now applicable to non-contact probe assemblies; in 7.5.2.3.2, the values of Table 5 have been modified; in 7.6.2, voltage tests of clearances are done without humidity preconditioning; pre-treatments for rigidity test from Clause 10 of Edition 2 have been moved to 9.2; Subclause 11.1 of Edition 2 has been deleted; addition of an exception for Type E probe assembly in 13.2. Removable parts of probe tips which bear markings are allowed; Figure F.1 has been modified; Annex G has been added, for determination of clearances for Table 2; Annex H has been added, covering line-to-neutral voltages for common mains supply systems.
