There are some subtleties to hydrostatic testing.

The actual test is something like:

fill tank with water and measure volume.

Increase pressure to 5/3 working pressure. The steel tank WILL expand so an additional volume of water must be added to the tank to reach this pressure.

Release pressure and measure NEW volume of tank.

To pass the test the new volume must be no more than 110% of the original volume.

This problem was initially encountered with SCUBA tanks. They are made as light as possible and are more easily dented than commercial tanks.

If you like you might want to select a "failed" tank that is fairly new and have it tested. It just may pass.

Here ya go

This issue has also been resolved with SCUBA tanks by tumbling.
