The standard that defines the minimum cup depth for brazed joints in medical gas piping is used to ensure proper joint makeup.

• A. ANSI/ASME
• B. NFPA 99
• C. CSA B51
• D. DIN EN 1252

Answer: (A)

The test is about which standard specifies the brazed joint geometry, including minimum cup depth, used in medical gas piping to ensure proper joint makeup. ANSI/ASME standards provide the fabrication and joining requirements for piping systems, including medical gas piping, and they define details like cup depth to ensure the brazed joint is properly filled and seals correctly. NFPA 99 governs safety and facility-wide requirements for healthcare systems but does not prescribe the brazing geometry itself. CSA B51 and DIN EN 1252 apply in their respective jurisdictions and are not the primary references for U.S. medical gas piping fabrication, making ANSI/ASME the appropriate standard in this context.
