scope:

This standard covers valves and fittings in sizes 1/2" through 2" NPS for use in drinking water system service-line between the main and the meter. Included are:

a) Buried valves and fittings that are designed to be in direct contact with the soil (corporation valves, service saddle clamps, and curb valves).

b) Non-buried valves and fittings that are not designed to be in direct contact with the soil (meter valves, check valves, meter fittings, and meter settings).

c) Fittings include various types of couplings and adapters.

Not included is:

d) Reduced pressure backflow preventers.

This Standard Practice establishes the minimum requirements that a drinking water service-line valve or fitting must possess at the time of manufacture. Details of design and manufacture, other than those stated in this standard, including such design and production tests to ensure that each valve or fitting will have these capabilities, remain the responsibility of the manufacturer.
