After the visual inspection on my cylinders they used a Dremel with an engraving burr to etch the collar. The number they etched on the collar of each cylinder consisted of four digits representing the month and year and began or ended with the letter E. When cylinders are recertified using visual inspection method for the second time they are supposed to use the letter F.
I believe when they do a pressure test they remove the valve from the cylinder. Don't have any idea what it costs, but by the time they get done and they reinstall the valve, they will need to purge the tank with propane. So with a pressure test it will probably be just as economical to purchase a new 20 lb cylinder. With a 30 pound cylinder or a less than 20 lb cylinder, a pressure test may be more economical, but not by much, so it may be worth one's while to just replace the cylinder.
