Preface:

This is the fifth edition of CSA C22.2 No. 239, Control and instrumentation cables, one of a series of Standards issued under the Canadian Electrical Code, Part II. It supersedes the previous editions, published in 2017, 2009, 1997, and 1991.

The main changes in this edition include
a) addition of PCS cable construction and corresponding markings;
b) addition of Clause 6.2.5 for the acid gas emission test and corresponding marking;
c) removal of option to perform smoothing and die cutting after accelerated aging for physical properties testing;
d) revision of criteria for retention of tensile strength and elongation after accelerated aging in Tables 8, 30, and 31; and
e) addition of Table 33 for colour coding of insulated PCS power conductors.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope:

1.1
This Standard applies to multiple-conductor control and instrumentation cables (including thermocouple cables and thermocouple extension cables) having a voltage rating not exceeding 1000 V and intended for installation in accordance with CSA C22.1, Canadian Electrical Code, Part I.
Note: The designations for such cables are “CIC” for unarmoured cables and “ACIC” for armoured cables.

1.2
This Standard applies to cables rated 1000 V, 600 V, 300 V, and 150 V, and to temperature ratings up to 105 °C. This Standard also includes specific requirements for high-temperature control and instrumentation cables rated 125 to 250 °C.

1.3
This Standard applies to multiple-conductor thermoplastic or thermoset-insulated assemblies, shielded or unshielded, twisted or cabled, paired, two conductors parallel or grouped into units, jacketed or unjacketed, sheathed or unsheathed, armoured or unarmoured, and any combinations thereof.

1.4
This Standard includes specific requirements for halogen-free limited-smoke control and instrumentation cables.

1.5
This Standard permits the inclusion of additional components, such as optical fiber members and communications wire used for installation purposes only. No requirements for such components are specified.

1.6
This Standard does not apply to cables intended for internal wiring of electrical equipment, e.g., switchboard and equipment wire, or to cables that undergo repeated flexing.

1.7
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.
