Cylinder Testing
Visual inspection, hydrostatic testing and valve servicing — and why inland divers care most.
Scuba cylinders require periodic inspection and testing, and a cylinder out of test will not be filled by any reputable facility.
Testing involves visual inspection of the interior for corrosion and contamination, hydrostatic testing to verify the cylinder still meets pressure specifications, and often valve servicing at the same time.
Not every dive shop does this in-house. Many send cylinders to a specialist facility, which affects turnaround and is worth knowing before you need it.
A diver who lives near several dive shops can drop a cylinder in whenever it suits. An inland diver in Canberra, or someone in a regional town, cannot.
Local fills and hydrostatic testing become important precisely because those divers cannot rely on a coastal shop for every service, and it is one of the main reasons inland dive centres exist at all.
Local standards and test intervals should always be supported by current Australian regulatory or standards information rather than generic overseas guidance.
Requirements differ between countries, and advice found on international forums frequently does not apply here.
Twinset manifolds, stage cylinders and rebreather cylinders all have their own considerations, and not every facility handles them.
Oxygen-clean cylinders in particular need to be tested and returned in a state that preserves the cleaning.

Frequently asked questions
How often do scuba cylinders need testing?
Intervals are set by Australian standards and differ for visual inspection and hydrostatic testing. Check current requirements with a testing facility rather than relying on overseas guidance.
Will a shop fill a cylinder that is out of test?
A reputable facility will not. The test date stamp is checked before filling.
Can I get testing done outside a capital city?
Many regional centres offer it, but availability varies. This is worth confirming if you live away from a major city.
