    Preface


    This volume contains the seventh edition of CSA B64.10, Selection and installation of backflow preventers, and the fourth edition of CSA B64.10.1, Maintenance and field testing of backflow preventers. CSA B64.10 supersedes the previous editions published in 2011, 2007, 2001, 1994, 1988 (as part of the CAN/CSA-B64 Series), and 1981. CSA B64.10.1 supersedes the previous editions published in 2011, 2007 and 2001.


    This edition includes the following major changes:


    a) updates to zone protection piping identification;


    b) addition of emergency eye wash station for zone protection;


    c) clarification on field testing installation;


    d) addition of cross-connection control surveyor specifications;


    e) removal of DCVAF double check valve for fire protection systems; and


    f) addition of requirements for enclosures with no minimum thermal resistance (R) value.


    The two Standards are intended as a guide for designers of potable water supply and plumbing systems in the selection of the proper type of device, for installers and owners in the installation and maintenance of the devices, and for inspection authorities in the testing of the devices after they have been installed. The Standards provide information on other methods of preventing contamination of potable water by backflow from back siphonage or back pressure.


    CSA B64.10 and CSA B64.10.1 provide selection criteria, installation and maintenance procedures, and techniques that represent the general state of the art, but should not be construed as all-inclusive, especially where procedures and techniques are altered to meet special conditions. Where there are problems with a specific installation, it is suggested that the manufacturer of the backflow preventer be consulted.


    These Standards were prepared by the Technical Committee on Backflow Preventers and Water Pressure Reducing Valves, under the jurisdiction of the Strategic Steering Committee on Construction and Civil Infrastructure, and have been formally approved by the Technical Committee.


    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.

    CSA B64.10:17 - Selection and installation of backflow preventers


    Scope


    1.1 Application


    This Standard specifies requirements for the selection and installation of backflow preventers. Additional information on how backflow due to back siphonage and back pressure occurs, and how to select and apply specific devices, is included in Annexes A, B, and C.


    1.2 Exclusions


    1.2.1

    This Standard does not cover


    a) construction requirements or performance tests, which are covered by the CSA B64 Series;


    b) plumbing supply fittings, which are covered by ASME A112.18.1/CSA B125.1;


    c) plumbing fittings, which are covered by CSA B125.3; and


    d) manually operated valves for use in plumbing systems, which are covered by ASME A112.4.14/ CSA B125.14.


    1.2.1

    This Standard does not specify requirements for materials, construction, or performance tests of backflow preventers. Such requirements are specified in the CSA B64 Series, in ASME A112.18.1/CSA B125.1, and in CSA B125.3. See Table 1.


    1.2.2

    This Standard does not specify requirements for maintenance or field testing after the initial installation. Such requirements are specified in CSA B64.10.1.


    1.3 Terminology


    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.


    1.4 Measurement


    This Standard is written in SI (metric) units. For conversion tables, see Annex D. Vacuum is expressed in pressure below ambient.
