CAN/CSA C22.2 No. 61010-2-202:21 PDF

CSA Preface 

This is the second edition of CSA C22.2 No. 61010-2-202, Safety requirements for electrical equipment for measurement, control and laboratory use - Part 2-202: Particular requirements for electrically operated valve actuators, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 61010-2-202 second edition, 2020-11). It supersedes the previous edition published in 2018 as CAN/CSA-C22.2 No. 61010-2-202 (adopted IEC 61010-2-202:2016). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. 

For brevity, this Standard will be referred to as CSA C22.2 No. 61010-2-202 throughout. 

This Standard is intended to be used in conjunction with CAN/CSA-C22.2 No. 61010-1:12, Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 1: General requirements (adopted IEC 61010-1:2010, with Canadian and US deviations); and Amendment 1:2018 to CAN/CSA-C22.2 No. 61010-1:12 (adopted IEC Amendment 1:2016, with Canadian and US deviations). 

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. 

This Standard was reviewed for Canadian adoption 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 Technical Committee. 

This Standard has been developed in compliance with 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 This clause of Part 1 is applicable, except as follows: 

1.1 Scope 

1.1.1 Equipment included in scope

 Replacement of the text by the following paragraphs: 

This part of IEC 61010 specifies the safety requirements for electric ACTUATORs and SOLENOIDs, as applied to valves, intended to be installed in an industrial process or discrete control environment. This part of IEC 61010 specifies: - particular safety requirements for general purpose electrically operated valve ACTUATORs and SOLENOIDs, - related verification tests. 

1.1.2 Equipment excluded from scope Addition at the end of the list: This standard excludes: aa) electric ACTUATORS and SOLENOIDs for use in domestic or commercial applications; 

NOTE 1 These are covered by other IEC or ISO standards, such as IEC 60730, etc. bb) electric ACTUATORs and SOLENOIDs performing a safety function;

NOTE 2 These are covered by other IEC or ISO standards, such as IEC 61508, etc. cc) positioners. 

NOTE 3 A positioner is defined as a physical unit delivering an additional, often mechanical, feedback to a mechanical final controlling element that improves its velocity and precision in IEC 60050-351:2013, 351-56-17. 

1.2 Object 

1.2.2 Aspects excluded from scope Addition at the end of the list: aa) mechanical parts/aspects of valves. 

1.2.101 Aspects included in other applicable standards Where electric ACTUATORs and SOLENOIDs are required to comply with requirements of other IEC or ISO standards, aspects fully covered in these standards can replace requirements as given in IEC 61010-1. Where aspects covered in IEC 61010-1 are not fully covered in these IEC or ISO standards, tests of IEC 61010-1 shall be conducted as far to ensure that no HAZARD can occur in NORMAL or in SINGLE FAULT CONDITION. NOTE IEC 61010-1:2010, Figure 15 of 14.1 gives a general overview of dealing with components within the scope of other IEC or ISO standards. A similar approach can be used for equipment and sub-assemblies. Example - Clauses 8 and 9.1 to 9.5 can generally be considered sufficiently covered where IEC 60079 has been applied.
