🔍 Key Concepts

• 46 CFR Part 54 – requirements for nameplates and stamping on pressure vessels • Difference between design information (like working pressure, approvals) and test conditions (like specific hydro or pneumatic tests) • How the Coast Guard shows that a pressure vessel meets USCG approval in addition to ASME requirements

💭 Think About

• Look at which of the choices represents something that would be permanently important over the whole life of the vessel, not just during a single test • Ask yourself: what must an inspector be able to identify at a glance on the vessel shell or nameplate to know it complies with USCG pressure‑vessel rules? • Consider which item would be the same every time you look at the nameplate, versus items that could change if a different test is performed later

✅ Before You Answer

• Review 46 CFR Part 54 sections on stamping and nameplates (marking of pressure vessels) and note every item listed as mandatory • Check whether test pressures are normally recorded in test reports and certificates rather than stamped on the vessel shell itself • Confirm which marking indicates that the pressure vessel meets Coast Guard authorization/inspection requirements beyond standard ASME construction
