Which standard covers socket-type CPVC fittings?

Which standard covers socket-type CPVC fittings?

• A. ASTM F 437 Standard for CPVC plastic pipe fittings
• B. ASTM F 439 Socket-type CPVC fittings, Schedule 80
• C. ASTM F 438 Socket-type CPVC fittings
• D. ASME B16.18 Standard for cast copper alloy solder joint fittings

Answer: (C)

Socket-type CPVC fittings are standardized to ensure a reliable solvent-weld connection with CPVC pipe. The standard that specifically covers socket-type CPVC fittings is ASTM F438. This standard defines the requirements for the socket portion, dimensions, and performance of CPVC socket fittings used with CPVC pipe. It’s more specific than the general CPVC pipe fittings standard (which covers CPVC fittings in a broader sense) and is distinct from the Schedule 80-specific standard (which is a subset) or from standards for other materials like copper alloy solder joint fittings. In CPVC piping systems used in NFPA 13R applications, selecting fittings listed to the appropriate standard (F438 for socket-type CPVC fittings) ensures proper compatibility and joint integrity.
