What is a hydrostatic test? Steel and aluminum cylinders should be tested every five years. Description . Quite often, after hydrostatic testing, the cylinder remains slightly larger than it was prior to the testing phase (known as permanent expansion). Prior to any test, all cylinders must be subjected to a solution heat treatment and aging treatment appropriate for the aluminum alloy used. A hydrostatic test involves pressurising the cylinder to its test pressure (usually 5/3 or 3/2 of the working pressure) and measuring its volume before and after the test.
