Do you pressure test dock hoses using 1.5 design pressure similar to testing pressure vessels?

My 2 cents: The EN standards cover a range of temperatures under which the hoses would be used:
To clarify that Dock Hoses are generally used in processing crude oils, refined petroleum products, liquefied petroleum gas (LPG), chemical products, petroleum/chemical vapors, and for ballasting/de-ballasting environment.
Testing Pressure should be 1.5 times working pressure (operating pressure) per EN 1765. However, ensure all hoses are hydrotested to maximum surge pressure at factory.
If project has surge considerations, then ensure this requirement is in the hose testing requirements.
Maximum Allowable Working Pressure (MAWP) - maximum gauge pressure permissible at the top of the equipment in its operating position …
