USCG Exam PracticeHydraulics and pneumatics
Under 46 CFR §28.880, nonmetallic flexible hose installed in a hydraulic system must be marked with which of the following information?
- A. The SAE J1475 compliance stamp, burst pressure rating, and installation date
- ✓ The manufacturer's name or trademark, type or catalog number, and maximum allowable working pressureCorrect
- C. The vessel's official number, the system's maximum operating pressure, and the hose inside diameter
- D. The SAE J1942 designation, hose length, and the date of last hydrostatic test
Why B is correct
46 CFR §28.880(j) requires that nonmetallic flexible hose be marked with the manufacturer's name or trademark, type or catalog number, and maximum allowable working pressure. SAE J1475 applies to hose end fittings under §28.880(i), not to hose marking. Vessel official numbers, installation dates, and hydrostatic test dates are not among the required markings in this section.
