    Preface


    This is the first edition of CSA Standard CAN/CSA—C22.2 No. 231, which is one of a series of Standards issued by Canadian Standards Association under Part II of the Canadian Electrical Code.


    A major objective of this Standard was to harmonize, where possible, with North American and IEC Standards. This edition adopts the IEC format and style, and is written in SI (metric) units. A number of requirements prepared by IEC Subcommittee 66E have been incorporated into this edition.

    This Standard is comprised of CAN/CSA—C22.2 No. 231.0, Electrical and Electronic Measuring and Test Equipment, and CAN/CSA—C22.2 No. 231.1, Test Probes.


    This Standard covers electrical and electronic measuring and test equipment, cord- or permanently—connected to supply circuits of 600 V and less, and intended for installation in accordance with the Rules of the Canadian Electrical Code, Part I. In addition, requirements for battery operated equipment have been included.


    Incorporated into this edition is Electrical Bulletin No. 556B, Requirements for Construction and Test of Electronic Instruments and Scientific Apparatus for Special Use and Applications, 1967.


    For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CSA Standard C22.2 No. 0, General Requirements--Canadian Electrical Code, Part II.


    This Standard was prepared by a Subcommittee of the Technical Committee on Environmental Products under the jurisdiction of the Standards Steering Committee on the Canadian Electrical Code, Part II, and was formally approved by these Committees.


    The following typefaces, when used within this Standard, denote the following:


    (a) roman type——construction requirements;


    (b) smaller roman type--explanatory matter for the construction requirements;


    (C) italic type--testing requirements; and


    (d) smaller italic type--explanatory matter for the testing requirements.

    CAN/CSA-C22.2 No. 231.0-M89 - Electrical and Electronic Measuring and Test Equipment


    Scope


    1.1.1

    This Standard applies to electrical, electronic, or electromechanical equipment designed to


    (a) measure or observe, and indicate quantities of


    (i) electrical, or


    (ii) electronic phenomena; or


    (b) supply


    (i) electrical, or


    (ii) electronic quantities for measuring or indicating purposes, or


    (c) measure or indicate electrical analogues of non-electrical phenomena.


    1.1.2 Constraints


    This Standard applies to equipment intended for installation and use in accordance with the Canadian Electrical Code, Part I, that


    (a) is rated for connection to supply circuits which exceed extra-low voltage and not power limited in accordance with Clause 14 and which do not exceed nominally:


    (i) 600 V, 3 phase, between phases for 3 phase supply circuits; or


    (ii) 250 V rms, single-phase, or dc;


    (b) is rated for connection to an extra-low voltage or power limited circuit and internally derives from that circuit a voltage or power in excess of those limitations according to Clause 14;


    (c) is rated for measuring, testing, or otherwise connecting to circuits operating in excess of extra-low voltage, or not power limited in accordance with Clause 14; or


    (d) is rated for connection to, or utilizing, extra-low voltage or power limited circuits.


    Additional Canadian Electrical Code, Part II Standard requirements shall apply to equipment for use in hazardous locations.


    Some requirements of this Standard do not apply to extra-low voltage and/or power limited circuits.


    1.1.3 Auxiliary or Accessory Equipment


    This Standard also applies to auxiliary equipment and accessories rated for use with electrical, electronic, or electromechanical equipment where auxiliary and accessory equipment is separate equipment which does not itself perform the desired function but is used in addition to or as a supplement to equipment according to Clause 1.1.1.


    1.1.4 Equipment Covered


    This Standard forms one of a series of specific parts.


    The General Requirements set forth in this Standard apply to all electrical and electronic equipment or accessories in relation to Clauses 1.1.1 and 1.1.3.


    Requirements that apply specifically to certain types or classes of electrical and electronic equipment are set forth in the CSA Standard CAN/CSA-C22.2 No. 231.1, Test Probes.


    In the event of conflict between the general requirements of this Standard and another standard in this series, the requirements of the specific standard (ie, CAN/CSA-C22.2 No. 231.1) relative to a certain type or class of equipment, shall apply.


    1.1.5 Equipment Not Covered


    These requirements do not apply to the following types of equipment:


    (a) medical laboratory and industrial process control equipment;


    (b) watt-hour meters and associated equipment installed by electric utility companies for measuring electrical energy and related quantities;


    (c) general use battery chargers, auxiliary supply sources, substitute power supplies, or laboratory-type power supplies not specifically rated for use with measuring or testing equipment.


    Specifically rated is defined as being


    (i) packaged with the equipment;


    (ii) referenced in an equipment marking; or


    (iii) referenced in the operating instructions packed with the equipment.


    1.1.6 Environmental Conditions


    Equipment according to this Standard is intended for use in enclosed locations where the air temperature is controlled and normally only nonconductive pollution occurs.


    The basic climatic conditions for heated or cooled enclosed lacations are (IEC Publication 654-1, Class B location)


    (a) temperature from 5°C to 40°C; equipment may occasionally be subjected to temperatures between -10°C and -5°C for short time periods;


    (b) altitude up to 2200 m;


    (c) relative humidity up to 85%, with wet bulb temperature not to exceed 27°C.


    1.1.7 Equipment with Telecommunication Features


    Equipment intended to be connected to a telecommunication network shall comply with the requirements of CSA Standard C22.2 No. 0.7, Equipment Electrically Connected to a Telecommunication Network.


    --------------------------------------------------------------------------------------------------------------------------------


    CAN/CSA-C22.2 No. 231.1-M89 - Test Probes


    Scope


    1.1

    This Standard applies to probes and probe assemblies for use with electrical, electronic, and electromechanical measuring and testing equipment covered by CSA Standard C22.2 No. 231.0.


    1.2 Measuring or Testing Probe Assemblies


    1.2.1 Measuring or Testing Probe Assembly


    A measuring or testing probe assembly for connection to a live circuit according to Clause 9.2 of CSA Standard C22.2 No. 231.0 shall be marked, constructed, and tested according to the applicable requirements of this Standard.


    1.2.2 Constraints


    This Standard applies to measuring or testing probe assemblies that are intended for measuring or testing


    (a) branch circuits up to 1000 V; or


    (b) ac or dc voltages up to 40 kV incorporated within electrical end-product equipment circuits.


    1.2.3 Items Not Covered


    This Standard does not apply to measuring or testing probe assemblies that are


    (a) intended for use with equipment other than that according to the scope of CSA Standard C22.2 No. 231.0;


    (b) intended for use exclusively in extra-low voltage and power limited applications (see Clause 14 of CSA Standard C22.2 No. 231.0); and


    (c) intended primarily for equipment-to-equipment interconnection (for example, IEEE interface bus).
