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.
if the specification you ve been given is to perform a hydro test at 16 bar then that should be 1 5 times the design pressure of 10 67 bar per b31 3 a pneumatic test should therefore be performed not at 16 bar but at 1 1 times the design pressure or 11 7 bar run the pneumatic pressure only as high as 11 7 bar
