Definitions, General Requirements, and Test Methods for Vacuum Breakers and
Backflow Preventers
Vacuum breakers and backflow preventers covered by the B64 Series
of Standards include only those devices that are designed for use
in potable water supply systems to prevent cross-connections.
Covers vacuum breakers of the hose connection type in sizes of
NPS-1/2, 3/4, and 1. HCVB devices incorporating a manual or
automatic draining feature are covered in CSA Standards B64.2.1
and B64.2.2, respectively.
Vacuum Breakers, Hose Connection Type (HCVB) with Manual Draining Feature
Covers vacuum breakers of the hose connection type in sizes of
NPS-1/2, 3/4, and 1. These devices incorporate a draining
feature that requires manual operation.
Vacuum Breakers, Hose Connection Type (HCVB) with Automatic Draining Feature
Covers vacuum breakers of the hose connection type in sizes of
NPS-1/2, 3/4, and 1. These devices incorporate an automatic
draining feature that does not require manual operation.
Covers vacuum breakers for use on laboratory faucets in a nominal
pipe size of 3/8 only, although inlet or outlet connections, or
both, may be different when so required for special
installations.
