ASME B16.15 is the standard for which item?

• A. ASME B16.15
• B. ASTM B 43
• C. CPVC Pipe
• D. Table 5.2.1

Answer: (A)

Standards tell you exactly which component they govern, so you know which document applies to a given part. ASME B16.15 defines the dimensions, thread forms, and pressure ratings for cast iron threaded fittings, meaning it specifically covers threaded cast iron elbows, tees, adaptors, and similar fittings used with cast iron pipe. That direct match makes it the correct reference for this item. The other options don’t fit as precisely: CPVC pipe has its own CPVC-specific standards, ASTM B43 covers cast iron pipe and fittings in general (not the precise threaded fittings category), and a table like Table 5.2.1 is not itself a standard.
