2.1 Applicable to Class I and II, Division 2 and Class III, Divisions 1 and 2
2.1.1 This standard applies only to equipment, circuits, and components for use in Class I and II, Division 2 and Class III, Divisions 1 and 2 hazardous (classified) locations as defined in the National Electrical Code® (NEC®) ANSI/NFPA 70 or in the Canadian Electrical Code (CEC) CSA C22.1.
NOTE 1 Some equipment designed for use in unclassified locations is permitted by the NEC® or CEC for installation in Division 2 locations. The judgment of acceptability for the installation would be determined by the authority having jurisdiction. Such equipment would not have the hazardous location marking or documentation described in this standard. It is anticipated that such equipment would comply with the other requirements in this standard and that the determination of compliance is elementary
(e.g., a nonarcing instrument inside a Type 4 or Type 12 enclosure used in a Class II, Division 2 location).

[Add the following]
The requirements of the IEC 60079 series of Standards cover protection with respect to explosion hazard only. The CAN/CSA-C22.2 No. 60079 series of Standards (based on the adoption of corresponding IEC Standards) is to be used in conjunction with other applicable Standards containing the appropriate electrical safety requirements for general use equipment.
[Add the following paragraphs]
The requirements of the IEC 60079 series of Standards cover protection with respect to explosion hazard only. The CAN/CSA-C22.2 No. 60079 series of Standards (based on the adoption of corresponding IEC Standards) is to be used in conjunction with other applicable Standards containing the appropriate electrical safety requirements for general use equipment. This Standard covers products that are intended to be installed or used in accordance with CSA C22.1, Canadian Electrical Code, Part I.
Group I electrical equipment intended for use in mines susceptible to firedamp is regulated by the provinces and territories of Canada. Such types of equipment (e.g., caplights) should be referred to the respective authority having jurisdiction.
This part of IEC 60079 provides guidance for the application of electrical resistance trace heating systems in areas where explosive atmospheres may be present, with the exclusion of those classified as requiring EPL Ga/Da (traditional relationship to Zone 0 and Zone 20
respectively). This standard also provides guidance for explosive atmospheres incorporating
the Division method of area classification that may be applied by some users of this standard.
NOTE Information on the Division method is given in NFPA 70 and CSA C22.1.
It provides recommendations for the design, installation, maintenance and repair of trace heating systems including associated control and monitoring equipment. It does not cover devices that operate by induction heating, skin effect heating or direct pipeline heating, nor those intended for stress relieving.
This Standard applies to line isolation monitors designed to be installed and used as an ancillary part of a single-phase isolated (ungrounded) power distribution system not exceeding 300 V in accordance with the rules of the CE Code, Part I, including any rules that are applicable particularly to anaesthetizing locations and other patient care areas in hospitals and other health care facilities.
This Standard applies to all line isolation monitors and includes requirements for the enclosure in which they are mounted for installation.
This Standard applies to monitors of a kind that are programmed to measure, periodically or continuously, an impedance to ground of each "side" of a single-phase power supply and any connected load and to activate an alarm whenever either or both of these impedances are equal to or less than a preset limit.
This Standard also applies to remote indicators designed to duplicate some or all of the alarm indications that are presented by a line isolation monitor.
This Standard does not include requirements for monitors for installations in hazardous locations, as Part I of the CE Code does not provide for their installation in such locations.
