Which standard provides general requirements for wrought copper tube?

• A. ASTM B 88
• B. ASTM B 251
• C. NFPA 13
• D. ASTM F 437

Answer: (B)

ASTM B251 is the standard that sets general requirements for wrought copper tube. It covers the overall specifications for copper tubes produced by drawing or extrusion, including aspects like dimensions, tolerances, chemical composition, mechanical properties, test methods, and labeling. This makes it the go-to reference for the broad class of wrought copper tubing used in plumbing and HVAC systems. Other standards here focus on different things: ASTM B88 is for seamless copper water tube, ASTM F437 deals with fittings, and NFPA 13 is a sprinkler system standard that doesn’t specify tube material requirements.
