Dive Bottle Test - Short & Curly's?

[Aimstraight]

.....There's no way to complete the tests without changing the valve, so you say "short & curlys" where they will say they've hit a brick wall because without a new valve they can't pressure test the re assembled unit....

Am I correct in thinking that the hydraulic test (~ 1.5 times its working pressure) is carried out on the cylinder itself (no valve), then the assembled unit (inc valve) is filled to its working pressure? As you say, the test centre probably call a halt until a resolution is agreed.
