How do I pressure test an old radiator?

I just bought a vintage radiator and would like to pressure test it prior to installing it. What psi should I test it at?

Thank you in advance for the help

    Re pressure test

    I usually plug one end of radiator with test gauge, put hose bib on other end. Fill to 30 psi water in a dry location, bleed out air so full of water at 30lbs, Leave for several hours and check over closely for any water leak. Many radiators are only rated for 30 psi so exceeding it may not be the best idea, even though we do most the time.  Good luck
