This Standard applies to cellular metal and cellular concrete floor raceways and fittings that are intended to be installed in ordinary locations in accordance with CSA C22.1, Canadian Electrical Code, Part I.

This Standard does not include requirements for the structural aspects nor for the effect on the fire resistance rating of the floor in which the system is installed.

These requirements do not include any features that are related only to the function of cellular metal and cellular concrete floor raceways as structural members.

This Standard does not apply to underfloor raceways covered by CSA C22.2 No. 80.

This Standard does not apply to raceways installed on the underside of the cellular floor that are considered wireways covered by CSA C22.2 No. 26.

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 (nonmandatory) to define their application.
