# §154.552. Cargo hose: Compatibility.


Liquid and vapor cargo hoses must:

- (a) Not chemically react with the cargo; and
- (b) **Withstand design temperature.**

# §154.554. Cargo hose: Bursting pressure.


Cargo hose that may be exposed to the pressure in the cargo tank, the cargo pump discharge, or the vapor compressor discharge must have a bursting pressure of at least five times the maximum working pressure on the hose during cargo transfer.


# §154.556. Cargo hose: Maximum working pressure.


A cargo hose must have a maximum working pressure not less than the maximum pressure to which it may be subjected and at least 1034 kPa gauge (150 psig).


# §154.558. Cargo hose: Marking.


Each cargo hose must be marked with the:

- (a) Maximum working pressure; and
- (b) **Minimum service temperature for service at other than ambient temperature.**

# §154.560. Cargo hose: Prototype test.

- (a) Each cargo hose must be of a type that passes a prototype test at a pressure of at least five times its maximum working pressure at or below the minimum service temperature.
- (b) Each cargo hose must not be the hose used in the prototype test.

# §154.562. Cargo hose: Hydrostatic test.


Each cargo hose must pass a hydrostatic pressure test at ambient temperature of at least one and a half times its specified maximum working pressure but not more than two-fifths its bursting pressure.
