Which standard defines socket-type CPVC plastic pipe fittings?

• A. ASTM F 438
• B. NFPA 251
• C. ASTM F 439
• D. ASTM F 442

Answer: (D)

Socket-type CPVC fittings are defined by a standard that sets the exact requirements for those socket joints, ensuring a proper fit with CPVC pipe and reliable solvent-cement connections. The standard that defines socket-type CPVC plastic pipe fittings is ASTM F442. It covers the dimensions, tolerances, materials, and performance criteria for these fittings, including the tests that confirm they will perform under pressure and resist leaks when joined with CPVC pipe using the appropriate adhesive system. The other options pertain to different CPVC components or related tests and do not specifically define socket-type CPVC fittings.
