Which ASTM standard defines seamless red brass pipe, 2009?

• A. ASTM B 43
• B. ASTM A 795
• C. ASTM B 32
• D. Water mist fire protection

Answer: (A)

Seamless red brass pipe is defined by an ASTM standard that specifically covers seamless copper alloy red brass pipe and tubing, including its composition, dimensions, tolerances, and manufacturing method. That standard is ASTM B43. It is the exact reference for this material form, which is why it’s the best choice for defining seamless red brass pipe. The other options don’t fit: ASTM A795 is for steel pipe used in water systems, not copper alloy red brass; ASTM B32 relates to a different copper alloy product (and not specifically seamless red brass pipe); and the choice about water mist fire protection refers to a system type rather than a material standard.
