Canadian Standards Association (operating as “CSA Group”), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for- profit, nonstatutory, voluntary membership association engaged in standards development and certification activities.

CSA Group standards reflect a national consensus of producers and users — including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment.

Individuals, companies, and associations across Canada indicate their support for CSA Group’s standards development by

volunteering their time and skills to Committee work and supporting CSA Group’s objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSA Group’s total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSA Group’s standards development activities.

CSA Group offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, CSA Group regularly and continually audits and inspects products that bear the

CSA Group Mark.

In addition to its head office and laboratory complex in Toronto, CSA Group has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, CSA Group has developed the necessary expertise to meet its corporate mission: CSA Group is an independent service

organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.

Preface

This is the second edition of CSA C22.2 No. 85, Rigid PVC boxes and fittings, one of a series of Standards issued under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 1989 and 1968.

For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CAN/CSA-C22.2 No. 0.

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

This Standard was prepared by the Subcommittee on Non-metallic Conduit, Tubing and Fittings, under the jurisdiction of the Technical Committee on Wiring Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee.

Interpretations: The Strategic Steering Committee on Requirements for Electrical Safety has provided the following direction for the interpretation of standards under its jurisdiction: “The literal text shall be used in judging compliance of products with the safety requirements of this Standard. When the literal text cannot be applied to the product, such as for new materials or construction, and when a relevant committee interpretation has not already been published, CSA's procedures for interpretation shall be followed to determine the intended safety principle”.

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. Notes:

1. Use of the singular does not exclude the plural (and vice versa) when the sense allows.

2. Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose.

3. This Standard was developed by consensus, which is defined by CSA Policy governing standardization — Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Standard.

4. To submit a request for interpretation of this Standard, please send the following information to inquiries@csagroup.org and include “Request for interpretation” in the subject line:

   1. define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;

   2. provide an explanation of circumstances surrounding the actual field condition; and

   3. where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.

      Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are available on the Current Standards Activities page at standardsactivities.csa.ca.

5. This Standard is subject to review five years from the date of publication, and suggestions for its improvement will be referred to the appropriate committee. To submit a proposal for change, please send the following information to inquiries@csagroup.org and include “Proposal for change” in the subject line:

   1. Standard designation (number);

   2. relevant clause, table, and/or figure number;

   3. wording of the proposed change; and

   4. rationale for the change.

Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSA's periodical Info Update, which is available on the CSA Web site at www.csa.ca.

Rigid PVC boxes and fittings

1. Scope

   
   

   1.1

   This Standard applies to rigid unplasticized poly (vinyl chloride)* boxes and fittings of the following types that are intended to be installed and used with rigid PVC conduit at a maximum working temperature of 75 °C in accordance with the rules of the Canadian Electrical Code, Part I:

   1. junction boxes with an interior volume of 1640 mL† or less that are intended to provide access to wiring and to enclose splices and taps but not to support wiring devices;

   2. conduit boxes with an interior volume of 1640 mL† or less that are intended to be used as pull boxes but not to enclose splices and taps or support wiring devices;

   3. surface mounted device boxes with an interior volume of 1640 mL† or less that are intended primarily to support wiring devices but may also be used as a pull box or to enclose wiring joints;

   4. box covers of the blank and device types;

   5. expansion joints that are intended to compensate for the linear expansion of a span of rigid PVC conduit;

   6. junction box terminal adapters that are intended to connect a length of PVC conduit by an elbow or other bend to a box;

   7. female adapters that are intended to connect a length of PVC conduit to a length of rigid metal conduit;

   8. reducers that are intended to connect lengths of two different sizes of rigid PVC conduit;

   9. caps that are intended to close the ends of unused lengths of rigid PVC conduit; and

   10. bell ends that are intended to provide a bushed opening at the open end of a length of rigid PVC conduit.

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

   † 1640 mL is the volume of trade size known as 100 cubic inches.

   
   

   1.2

   General requirements applicable to this Standard are given in CSA C22.2 No. 0, General Requirements — Canadian Electrical Code, Part II.

   
   

   1.3

   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.
