CSA C22.2 NO. 61010-2-030:25

Preface This is the harmonized CSA Group and ULSE standard for Safety requirements for electrical equipment for measurement, control, and laboratory use – Part 2-030: Particular requirements for equipment having testing or measuring circuits . It is the third edition of CSA C22.2 No. 61010-2-030 and the third edition of UL 61010-2-030. This edition of CSA C22.2 No. 61010-2-030 supersedes the previous edition published December 21, 2018. This harmonized standard is based on IEC 61010-2-030, third edition: Safety requirements for electrical equipment for measurement, control, and laboratory use – Part 2-030: Particular requirements for equipment having testing or measuring circuits, issued September 2023. IEC 61010-2-030 is copyrighted by the IEC. This harmonized standard was prepared by CSA Group and ULSE. The efforts and support of the Technical Harmonization Subcommittee, on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the standard. This standard was reviewed by the CSA Subcommittee on Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been developed in compliance with the Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope and object IEC 61010-1:2010, Clause 1 and IEC 61010-1:2010/AMD1:2016, Clause 1 apply except as follows: 1.1.1 Equipment included in scope Replace the existing text with the following: This document specifies safety requirements for equipment having testing or measuring circuits which are connected for test or measurement purposes to devices or circuits outside the measurement equipment itself. These include measuring circuits which are part of electrical test and measurement equipment, laboratory equipment, or process control equipment. These circuits in equipment have additional protective means between the circuit and an operator. NOTE These testing and measuring circuits can, for example: - measure voltages in circuits of other equipment, - measure temperature of a separate device via a thermocouple, - measure force on a separate device via a strain gauge, - inject a voltage or current onto a circuit to analyse or test a new design. This group safety publication focusing on safety essential requirements is primarily intended to be used as a product safety standard for the products mentioned in the scope, but is also intended to be used by technical committees in the preparation of publications for products similar to those mentioned in the scope of this document, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of its publications. 1.2.1 Aspects included in scope Replace item c) of the second paragraph with the following new item c): c) spread of fire or arc flash from the equipment (see Clause 9); Replace the third paragraph with the following two new paragraphs: Requirements for protection against HAZARDS arising from NORMAL USE, REASONABLY FORESEEABLE MISUSE and ergonomic factors are specified in Clause 16 and Clause 101. Annex BB provides guidance to equipment manufacturers on HAZARDS that should be considered for equipment intended for performing tests and measurements on hazardous conductors, including MAINS conductors and telecommunication network conductors.
