Cables and cable glands for use in hazardous locations

1.1 General

This Standard applies to

a) cables for use in hazardous locations in accordance with CSA C22.1, Canadian Electrical Code, Part I (CE Code, Part I); and
b) cable glands for use in Class I, Division 1 or Class II, Division 1 hazardous locations in accordance with the CE Code, Part I.

The requirements in this Standard are in addition to the basic electrical requirements applicable to such cables and cable glands for use in locations other than hazardous locations.

Notes: 

1) Cable glands may be approved with an Ex method of protection according to the CAN/CSA-C22.2 No. 60079 series of standards without demonstrating compliance to this Standard.
2) Cable glands for use in Class I, Division 2 or Class II, Division 2 are not covered by this Standard because their requirements are dictated by the equipment to which they are connected. For example, an explosion-proof box installed in a Class I, Division 2 location requires the use of a Class I, Division 1 cable gland.

1.2 Terminology

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.
