Which table specifies pipe materials and dimensions for systems?

• A. Solder Alloys
• B. CPVC Pipe
• C. Table 5.2.1
• D. ASTM B 32

Answer: (C)

In NFPA 13R, the information that ties together what piping materials are allowed and what sizes they can be is found in a single reference table. This table lists the acceptable pipe materials and their corresponding nominal dimensions, giving designers a clear, standardized basis for selecting piping and ensuring the system meets performance and compatibility requirements. The other options point to a solder alloy, a specific material (CPVC Pipe), or a standard for copper tube, none of which provide the comprehensive listing of materials and dimensions needed for system design. So the table that combines both material types and their allowable dimensions is the one labeled Table 5.2.1.
