Which standard specifies CPVC plastic pipe, SDR-PR?

Which standard specifies CPVC plastic pipe, SDR-PR?

• A. ASTM F 438
• B. NFPA 251
• C. ASTM F 442
• D. AWS A5.8

Answer: (C)

CPVC SDR-PR is a designation for CPVC plastic pipe defined by a standard that covers CPVC pipe and fittings, including its wall thickness, dimensions, and pressure ratings. ASTM F442 is the standard that specifies CPVC plastic pipe and fittings with the SDR-PR designation, ensuring the pipe meets the properties needed for pressure-rated sprinkler use and compatibility with CPVC fittings. The other standards point to completely different areas—NFPA 251 is about fire testing of building assemblies, AWS A5.8 relates to welding electrodes, and the remaining standard does not define CPVC SDR-PR.
