    To hydro a tank they pump water into it at 5/3s the working pressure of the tank. For example, a 3000 psi tank is tested at 5000 psi, and the displacement between 0 psi/ambient psi and the 5000 psi is measured.

    As long as expansion of the tank falls within the manufacturer's guidelines, the tanks is deemed safe for use.

    Hope this helps,
