operated appliances when operated in the battery mode.

Examples of appliances that are within the scope of this standard are
battery-operated appliances and other DC supplied appliances for skin beauty care;

- battery-operated appliances and other DC supplied appliances for skin beauty care;
- appliances with high frequency outputs including equipment for heat-producing effects on the skin; - appliances with medium frequency outputs including interferential outputs, for skin stimulation or muscle stimulation;
- appliances with low frequency outputs (e.g. faradic currents) for application such as skin stimulation or muscle stimulation;

           - physical, sensory or mental capabilities; or
           - lack of experience and knowledge prevents them from using the                       appliance safely without supervision or instruction;
– children playing with the appliance.

NOTE 103 Attention is drawn to the fact that

– it is recognized that persons having very extensive and complex disabilities can have needs beyond the level addressed in this standard.
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
– in many countries, additional requirements can be specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.

This standard does not apply to

– appliances intended exclusively for industrial purposes;

Scope for CSA C22.2 No. 24:21

1.1
This Standard applies to temperature-indicating and -regulating equipment* for voltages up to and including 600 V between conductors and intended for general household and industrial use in nonhazardous locations, in accordance with the Rules of CSA C22.1, Canadian Electrical Code, Part I (CEC, Part I).

* For convenience, the shorter term equipment is sometimes used in this Standard.

1.2
This Standard applies to electrical control equipment for air conditioning, heating, lighting, cooling, refrigeration, cooking appliances, safety controls, and other similar appliance controls.

1.3
This Standard does not apply to dimmers and extra-low-voltage equipment other than safety controls and room thermostats with heat anticipators.

1.4
In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

This part of IEC 60079 is applicable to electrical equipment protected by enclosure and surface temperature limitation for use in explosive dust atmospheres. It specifies requirements for design, construction and testing of electrical equipment and Ex Components.

This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence.

This standard does not apply to dusts of explosives, which do not require atmospheric oxygen for combustion, or to pyrophoric substances.

This standard does not apply to electrical equipment or Ex Components intended for use in underground parts of mines as well as those parts of surface installations of such mines endangered by firedamp and/or combustible dust.

This standard does not take account of any risk due to an emission of flammable or toxic gas from the dust.

Consideration of additional protective measures is required where the application of electrical equipment is in atmospheres, which can contain combustible dust as well as explosive gas, whether simultaneously or separately.

Where the electrical equipment has to meet other environmental conditions, for example, protection against ingress of water and resistance to corrosion, additional measures can be necessary. The measures used should not adversely affect the integrity of the enclosure.

This Part 3 of CSA-C22.2 No. 62109 covers the particular safety requirements for electronic elements that are mechanically and/or electrically incorporated with photovoltaic (PV) modules or systems. Mechanically and/or electrically incorporated means that the whole combination of electronic device with the photovoltaic element is sold as one product. Nevertheless, tests provided in this document may also be used to evaluate compatibility of PV modules and electronic devices that are sold separately and are intended to be installed close to each other.

Items included in the scope:

Electronic devices combined with PV modules that perform functions such as, but not limited to, DC-DC or DC-AC power conversion, active diodes, protection, control, monitoring, or communication. These requirements specifically address such electronic devices used in combination with flat-plate photovoltaic (PV) modules.

NOTE It is acknowledged that the physical design of products covered by this scope may vary widely, it is anticipated that the requirements of this document may need to evolve to meet the unique safety requirements of such products, particularly if the photovoltaic element of the product is not of a flat-plate configuration. As an example, this document does not fully address the safety requirements of building-integrated photovoltaics (BIPV) and building-attached photovoltaics (BAPV) products, although they would fall under the scope of this document. The purpose of the requirements of this part of CSA-C22.2 No.62109 is to provide additional safety-related testing requirements for the following types of integrated electronics, collectively referred to as module integrated equipment (MIE):

a) Type A MIE where the PV element can be evaluated as a PV module according to CAN/CSA-C22.2 No. 61730-1 and CAN/CSA-C22.2 No. 61730-2 independently from the electronic element;
b) Type B MIE where the PV element cannot be evaluated as a PV module according to CAN/CSA-C22.2 No. 61730-1 and CAN/CSA-C22.2 No. 61730-2 independently from the electronic element.

Items excluded from the scope:

PV modules with only one or more bypass diodes as the combined or integrated element. Such products are covered by CAN/CSA-C22.2 No.  61730-1 and CAN/CSA-C22.2 No.  61730-2.

Aspects included and excluded from scope:

All aspects of CAN/CSA-C22.2 No. 62109-1:2016 apply. Addition to the list “excluded from the scope” is evaluating the MIE to CAN/CSA-IEC 61215-1.
