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 1.1 Scope 1.1.1 Equipment included in scope This part of IEC 61010 specifies general safety requirements for the following types of electrical equipment and their accessories, wherever they are intended to be used. a) Electrical test and measurement equipment This is equipment which by electromagnetic means tests, measures, indicates or records one or more electrical or physical quantities, also non-measuring equipment such as signal generators, measurement standards, power supplies for laboratory use, transducers, transmitters, etc. NOTE 1 This includes bench-top power supplies intended to aid a testing or measuring operation on another piece of equipment. Power supplies intended to power equipment are within the scope of IEC 61558 (see 1.1.2 h)). This standard also applies to test equipment integrated into manufacturing processes and intended for testing manufactured devices. NOTE 2 Manufacturing test equipment is likely to be installed adjacent to and interconnected with industrial machinery in this application. b) Electrical industrial process-control equipment This is equipment which controls one or more output quantities to specific values, with each value determined by manual setting, by local or remote programming, or by one or more input variables. c) Electrical laboratory equipment This is equipment which measures, indicates, monitors, inspects or analyses materials, or is used to prepare materials, and includes in vitro diagnostic (IVD) equipment. This equipment may also be used in areas other than laboratories; examples include self-test IVD equipment to be used in the home and inspection equipment to be used to check people or material during transportation. 1.1.2 Equipment excluded from scope This standard does not apply to equipment within the scope of: a) IEC 60065 (Audio, video and similar electronic apparatus); b) IEC 60204 (Safety of machinery - Electrical equipment of machines); c) IEC 60335 (Household and similar electrical appliances); d) IEC 60364 (Electrical installations of buildings); e) IEC 60439 (Low-voltage switchgear and controlgear assemblies); f) IEC 60601 (Medical electrical equipment); g) IEC 60950 (Information technology equipment including electrical business equipment, except as specified in 1.1.3); h) IEC 61558 (Power transformers, power supply units and similar); i) IEC 61010-031 (Hand-held probe assemblies); j) IEC 61243-3 (Live working - Voltage detectors - Part 3: Two-pole low-voltage type). 1.1.2DV DR Modification of Clause 1.1.2 to add the following as new items kDV) and lDV): kDV) IEC 62368-1 (Audio/Video, Information and Communication Technology Equipment – Part 1: Safety Requirements). lDV) UL/ULC 1389 Plant Oil Extraction Equipment and Systems. 1.1.3 Computing equipment This standard applies only to computers, processors, etc. which form part of equipment within the scope of this standard or are designed for use exclusively with the equipment. NOTE Computing devices and similar equipment within the scope of IEC 60950 and conforming to its requirements are considered to be suitable for use with equipment within the scope of this standard. However, some of the requirements of IEC 60950for resistance to moisture and liquids are less stringent than those in this standard (see 5.4.4 second paragraph)). 1.1.3DV DR Modification of Clause 1.1.3 NOTE to revise as follows: Replace “IEC 60950” with “IEC 60950 or IEC 62368-1” in two places. 1.1.4DV DR Addition of the following referencing the National Electrical Code and the Canadian Electrical Code: This standard applies to equipment: a) To be employed in accordance with ANSI/NFPA 70, National Electrical Code® (NEC); b) Designed to comply with the general requirements of CAN/CSA C22.2 No. 0 and to be installed in accordance with the Canadian Electrical Code (CEC), Part I, CSA C22.1; or c) Both (a) and (b). 1.1.5DV DR Addition of the following new sub-clause: 1.1.5DV.1 Gas, vapor and voltage detectors or sensors Equipment intended to measure, sense or detect one or more electrical or physical quantities that identify an imminent hazard and used for signalling, may use this standard only when no alternative standard exists. Note 1 This standard is considered not to apply to gas detectors and similar equipment within the scope of ANSI/UL 2034, ANSI/UL 2075, CSA C22.2 No. 205, or ULC-S588.
