330. During the annual inspection by the owner, each nonmetallic oil transfer hose must not burst, bulge, leak, or abnormally distort under static liquid pressure. Which defines the minimum test pressure?

The minimum test pressure for nonmetallic oil transfer hoses is 11⁄2 times the maximum allowable working pressure, as mandated by 33 CFR 154.500. This regulation establishes the test pressure based on the hose's design rating, not external factors like relief valve settings, pump discharge pressure, or arbitrary psi values.
