1 Scope and Object
1.1 Scope
This International Standard specifies general safety requirements for electrical equipment intended for professional, industrial process, and educational use, including equipment and computing devices for:
This Standard applies to the safety of such equipment designed to be installed and used in accordance with the rules of the Canadian Electrical Code, Part I.
Products covered by the scope of this Standard are also subject to the requirements of CSA Standard CAN/CSA-C22.2 No. 0.
This Part 1 of the standard applies to the equipment defined in (a) to (c) below, when used under the environmental conditions of 1.4.
(a) Electrical measurement and test equipment
This is equipment which by electrical means measures, indicates or records one or more electrical or non-electrical quantities, also non-measuring equipment such as signal generators, measurement standards, power supplies, transducers, transmitters, etc.
(b) Electrical 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 or analyses substances, or is used to prepare materials.
This equipment may also be used in areas other than laboratories.
1.1.1 Aspects excluded from scope
This Part 1 of the standard does not cover:
NOTE - Servicing personnel are expected to be reasonably careful in dealing with obvious hazards, but the design should protect again st mishap by the use of warning labels, shields for hazardous voltage terminals, segregation of low-voltage circuits from hazardous voltages, etc. More important, servicing personnel should be trained against unexpected hazards.
1.1.2 Equipment excluded from scope
This Part 1 does not apply to:
1.1.3 Computing equipment
This Part 1 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 950 and complying with its requirements are considered to be suitable for use with equipment within the scope of this Part 1.
1.2 Object
The purpose of the requirements of this Part 1 is to ensure that the design and methods of construction used provide adequate protection for the OPERATOR and the surrounding area against:
NOTE - Attention is drawn to the existence of additional requirements which may be specified by national authorities responsible for health and safety of labour forces.
1.3 Verification
This Part 1 also specifies methods of verifying, through inspection and type testing, that the equipment meets the requirements of this standard.
NOTE - Recommendations for ROUTINE TESTS are given in annex K.
1.4 Environmental conditions
This Part 1 applies to equipment designed to be safe at least under the following conditions:
Process control equipment used in extended environments shall comply with CSA Standard C22.2 No. 142.
This Standard includes Canadian Deviations.
1.1 Scope
This International Standard specifies general safety requirements for electrical equipment intended for professional, industrial process, and educational use, including equipment and computing devices for:
- measurement and test;
- control;
- laboratory use;
- accessories intended for use with the above (e.g. sample handling equipment).
This Standard applies to the safety of such equipment designed to be installed and used in accordance with the rules of the Canadian Electrical Code, Part I.
Products covered by the scope of this Standard are also subject to the requirements of CSA Standard CAN/CSA-C22.2 No. 0.
This Part 1 of the standard applies to the equipment defined in (a) to (c) below, when used under the environmental conditions of 1.4.
(a) Electrical measurement and test equipment
This is equipment which by electrical means measures, indicates or records one or more electrical or non-electrical quantities, also non-measuring equipment such as signal generators, measurement standards, power supplies, transducers, transmitters, etc.
(b) Electrical 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 or analyses substances, or is used to prepare materials.
This equipment may also be used in areas other than laboratories.
1.1.1 Aspects excluded from scope
This Part 1 of the standard does not cover:
- reliable function, performance or other properties of the equipment;
- servicing (repair);
- protection of servicing (repair) personnel.
NOTE - Servicing personnel are expected to be reasonably careful in dealing with obvious hazards, but the design should protect again st mishap by the use of warning labels, shields for hazardous voltage terminals, segregation of low-voltage circuits from hazardous voltages, etc. More important, servicing personnel should be trained against unexpected hazards.
1.1.2 Equipment excluded from scope
This Part 1 does not apply to:
- electric power equipment, for example power electronics;
- machine tools and their controls (see IEC 204);
- Class 0,5, 1 and 2 alternating current watt-hour meters (see IEC 521);
- medical electrical equipment within the scope of IEC 601;
- biological amplifiers which link humans to equipment in research or teaching contexts;
- type-tested and partially type-tested assemblies of lowvoltage switchgear and controlgear (see IEC 439-1);
- circuits and equipment which are part of the building electrical installation (see IEC 364);
- computers, processors and similar equipment, except as specified in 1 .1.3 (see IEC 950);
- transformers separate from the equipment (see IEC 742);
- equipment intended for household use (see IEC 335);
- equipment intended for use in explosive gas atmospheres (see IEC 79).
1.1.3 Computing equipment
This Part 1 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 950 and complying with its requirements are considered to be suitable for use with equipment within the scope of this Part 1.
1.2 Object
The purpose of the requirements of this Part 1 is to ensure that the design and methods of construction used provide adequate protection for the OPERATOR and the surrounding area against:
- electric shock or burn (see clause 6);
- mechanical hazards (see clauses 7 and 8);
- excessive temperature (see clause 9);
- spread of fire from the equipment (see clause 9);
- effects of radiation, including lasers sources, sonic and ultrasonic pressure (see clause 12);
- liberated gases, explosion and implosion (see clause 13).
NOTE - Attention is drawn to the existence of additional requirements which may be specified by national authorities responsible for health and safety of labour forces.
1.3 Verification
This Part 1 also specifies methods of verifying, through inspection and type testing, that the equipment meets the requirements of this standard.
