| # | Inspection Item | Method | P / F / NA | Notes |
|---|---|---|---|---|
| 1. Pre-Test External Inspection | ||||
| 1 | Cylinder identification markings legible (serial, manufacturer, date) | INSPECT | ||
| 2 | External corrosion assessment (general and localised) | INSPECT | ||
| 3 | Dent and gouge measurement with depth gauge | MEASURE | ||
| 4 | Arc burns or heat damage assessment | INSPECT | ||
| 5 | Neck thread condition (no cracks, corrosion, or damage) | INSPECT | ||
| 6 | Foot ring and collar condition | INSPECT | ||
| 7 | Valve thread condition and compatibility | INSPECT | ||
| 2. Internal Inspection | ||||
| 8 | Internal corrosion assessment (visual/borescope) | INSPECT | ||
| 9 | Pitting depth measurement (max pit depth recorded) | MEASURE | ||
| 10 | Contamination or residue present | INSPECT | ||
| 11 | Cylinder lining condition (if fitted) | INSPECT | ||
| 12 | Internal coating integrity (if applicable) | INSPECT | ||
| 3. Weight and Capacity Check | ||||
| 13 | Tare weight comparison (reject if >5% loss for steel) | MEASURE | ||
| 14 | Water capacity measurement recorded | MEASURE | ||
| 15 | Wall thickness measurement (UT if required) | MEASURE | ||
| 4. Hydrostatic Test Procedure | ||||
| 16 | Cylinder filled and purged of air completely | VERIFY | ||
| 17 | Test pressure applied and held for minimum 30 seconds | TEST | ||
| 18 | Permanent expansion measured and recorded | MEASURE | ||
| 19 | Elastic expansion measured and recorded | MEASURE | ||
| 20 | Rejection ratio calculated (reject if >10% steel, >5% aluminium) | MEASURE | ||
| 21 | No visible leaks or distortion during test | INSPECT | ||
| 5. Post-Test Assessment | ||||
| 22 | No residual deformation after pressure release | INSPECT | ||
| 23 | External surface re-examined post-test | INSPECT | ||
| 24 | Thread condition verified post-test | INSPECT | ||
| 25 | Cylinder dried internally before return to service | VERIFY | ||
| 6. Marking and Certification | ||||
| 26 | Test date stamp applied to cylinder | VERIFY | ||
| 27 | Test station identification mark applied | VERIFY | ||
| 28 | Next test date recorded (10 years steel, 5 years composite) | VERIFY | ||
| 29 | Colour coding updated if required for service type | VERIFY | ||
| 30 | Condemned cylinders rendered unserviceable (drilled/crushed) | VERIFY | ||
