🔍 Key Concepts

• 46 CFR Part 56 – Piping Systems and Appurtenances • Specific Coast Guard requirements for fuel oil service piping tests • Difference between hydrostatic test pressure and design/allowable pressure

💭 Think About

• Look at which options actually describe a hydrostatic test requirement that would normally apply to fuel oil service piping, rather than to weld inspection or relief valve settings. • Ask yourself: does Coast Guard usually require testing at exact design pressure, or at some multiple of maximum allowable working pressure for safety margin? • Consider which answer sounds like a general piping code requirement vs. something very specific to new fuel oil service piping between pumps and burners.

✅ Before You Answer

• Verify in 46 CFR Part 56 what is required specifically for fuel oil service piping tests (not just any piping). • Check which choice correctly uses the term hydrostatic test with a clear multiple of maximum allowable pressure and a stated minimum pressure, if any. • Make sure the option you pick actually describes a pressure test, not a weld examination or an unrelated procedure.
