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 reference 6 below).
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.
