Although Romano cheese is traditionally made in Italy from ewe's milk (Pecorino) the following recipe is prepared for a 2 gallon version of cows milk (which would technically be called Vacchino Romano).
Strength is usually tested by measuring permanent deformation of the container. Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time.
The best example is Hydrotest, here the Vessel(any pressure vessel) is filled with water to test whether the vessel can withstand the Design pressure, after filling with water, Vessel is pressurized to 1.3 X Design pressure (important is vessel dimensions will not change ) to check whether the vessel leaks or burst.
