Preface

This is the third edition of CSA C22.2 No. 174, Cables and cable glands for use in hazardous locations, one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 1984 and 1981.

The major changes in this edition are as follows:

a) removal of requirements that are addressed in other standards;

b) addition of supplementary jacket testing for unarmoured cables to ensure robustness during installation; and

c) reorganization for clarity and consistency with current practice.

Scope

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, II, and III 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.

Note: 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.

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.

1.3 Units of measure

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
