1.1

The CSA B64 Series covers vacuum breakers and backflow preventers that are used in potable water supply systems to prevent cross‑connections.

1.2

This Standard specifies definitions, general requirements, test methods, markings, and instructions that are common to some or all of the CSA B64 Series.

1.3

This Standard is not a complete Standard in itself and is intended to be used in conjunction with one of the Standards in the CSA B64 Series to form a complete Standard for a particular type of vacuum breaker or backflow preventer.

1.4

In CSA standards, “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.

1.5

This Standard is written in SI (metric) units; for conversion tables, see Annex A. Vacuum is expressed in pressure below ambient. All pipe sizes are shown as nominal pipe sizes (NPS).

1.1 Portée de la présente norme

La présente norme décrit les processus de livraison des bâtiments modulaires volumétriques permanents, dont les modules sont construits dans une usine. Cette norme spécifie les procédures pour :

la conception;

le contrôle de la qualité des constructions modulaires;

les approbations;

la logistique, le transport et l’entreposage;

les travaux d’aménagement non modulaires et modulaires;

le levage, le positionnement et la pose;

l’installation et la finition; et

la mise en service et le transfert.

1.2 Exclusions

La présente norme ne vise pas la procédure de certification en usine des bâtiments, des modules ou panneaux.

Note : Voir la CSA A277 pour la procédure de certification en usine des bâtiments, des modules ou des panneaux.

1.3 Terminologie

Dans cette norme, le terme « doit » indique une exigence, c’est-à-dire une prescription que l’utilisateur doit respecter pour assurer la conformité à la norme; « devrait » indique une recommandation ou ce qu’il est conseillé, mais non obligatoire de faire; et « peut » indique une possibilité ou ce qu’il est permis de faire.

 

Les notes qui accompagnent les articles ne comprennent pas de prescriptions ni de recommandations. Elles servent à séparer du texte les explications ou les renseignements de nature informative qui ne font pas proprement partie de la norme.

 

Les notes au bas des figures et des tableaux font partie de ceux-ci et peuvent être rédigées comme des prescriptions.

 

Les annexes sont qualifiées de normatives (obligatoires) ou d’informatives (facultatives) pour en préciser l’application.

1.4 Unités de mesure

Les valeurs indiquées en unités SI constituent les valeurs officielles dans cette norme. Les valeurs entre parenthèses sont données à titre d’information et pour fins de comparaison seulement.

Scope

1.1

The CSA O80 Series of Standards specifies requirements related to the preservation and fire retardance of wood through chemical treatment (pressure and thermal impregnation). The subjects covered include materials and their analysis, pressure and thermal impregnation procedures, and fabrication and installation to put treated wood into service.

1.2

This Standard lists reference publications and provides definitions applicable to the entire CSA O80 Series of Standards. This Standard also describes how the CSA O80 Series of Standards differs from related AWPA Standards and addresses the need for preservative registration. Recommendations on the use of the CSA O80 Series of Standards and related AWPA Standards can be found in Annex A.

Note: In Canada, preservative registration is carried out through Health Canada’s Pest Management Regulatory Agency.

1.3

The requirements and recommendations of the CSA O80 Series of Standards are based solely on the treatment efficacy of the chemicals in question. The CSA O80 Series of Standards does not necessarily take all laws and regulations into account.

Note: It is the responsibility of the users of the CSA O80 Series of Standards to ensure that their use of preservatives does not conflict with applicable laws and regulations.

1.4

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.

Profile wall pipe includes only open profile with smooth interior and sizes based on controlled inside diameter. Open profile pipe is of an annular construction.

Notes:

1) Pipe and fittings manufactured in accordance with this Standard should be installed in accordance with CSA B182.11.

2) Refer to Annex A for recommended quality control test frequencies.

3) Refer to Annex B for base inside diameters.

4) Refer to Annex C for fitting patterns of the lay length of fittings covered by this Standard.

5) Annex D should be followed to ensure that the requested products are described adequately.

6) Annex E should be followed to ensure that the requested products are described adequately.

7) Appropriate structural design criteria for PP storm sewer pipe can be found in Appendix X2 of ASTM F2881/F2881M.
