Which standard covers cast copper alloy solder joint fittings?

Which standard covers cast copper alloy solder joint fittings?

• A. ASME B16.18 Standard for cast copper alloy solder joint fittings
• B. ASME B16.22 Standard for wrought copper and copper alloy fittings
• C. ASME B16.11 Standard for forged fittings, socket-welding and threaded
• D. ASTM F 439 Standard for socket-type CPVC fittings, Schedule 80

Answer: (A)

Cast copper alloy solder-joint fittings are governed by a standard that specifically covers cast copper alloy components with soldered connections. That standard is ASME B16.18. It defines the dimensions, tolerances, and pressure ratings for cast copper alloy solder-joint fittings like elbows, tees, and adapters. The other standards address different manufacturing methods or materials: B16.22 covers wrought copper and copper alloy fittings (not cast); B16.11 covers forged fittings for socket-welding and threaded connections; ASTM F439 covers CPVC fittings, Schedule 80, which are plastic and not copper.
