The composite SCBA Cylinder test cycle is on a (5) five-yearly basis.

Imported New Cylinders

It should be noted that by the Gas Cylinder Test Scheme and AS2337 & AS2030.

A new cylinder must be tested, and bear a current Australian Gas Cylinder Test Stamp prior to the first fill.

Before getting re-gassed, any older cylinders must be checked to see if the Gas Cylinder Test Stamp is current.

Example of an Australian Gas Cylinder Test Stamp Test Station mark for gas cylinder testing.

Failing to do so leaves the operator and the re-filler at risk of injury and prosecution if someone is injured.
