NOTE: For extremely low working temperatures in the 0˚F to minus 200˚F range, it is recommended that a joint material melting at or above 1100˚F be
employed (see Note
(6)
).
(1)
Standard water tube sizes per ASTM B 88.
(2)
Ratings up to 8 inches in size are those given in ASME B16.22 Wrought Copper and Copper Alloy Solder Joint Pressure Fittings and ASME B16.18
Cast Copper and Copper Alloy Solder Joint Fittings . Rating for 10- to 12-inch sizes are those given in ASME B16.18 Cast Copper and Copper Alloy
Solder Joint Pressure Fittings .
(3)
Using ASME B16.29 Wrought Copper and Wrought Copper Alloy Solder Joint Drainage Fittings — DWV , and ASME B16.23 Cast Copper Alloy
Solder Joint Drainage Fittings — DWV
.
(4)
Alloy designations are per ASTM B 32.
(5)
The Safe Drinking Water Act Amendment of 1986 prohibits the use in potable water systems of any solder having a lead content in excess of 0.2%.
(6)
These joining materials are defined as brazing alloys by the American Welding Society.
