How frequently do scuba cylinders require a pressure test?

Scuba cylinders require a pressure test at intervals ranging from one to five years to ensure that they are safe for continued use. This testing is crucial because it assesses the integrity and structural soundness of the cylinder, which can degrade over time due to factors like corrosion, wear and tear, or damage from usage.

The range of one to five years typically depends on the material of the cylinder, the service conditions it has been subjected to, and the regulations of the country in which it is being used. Some regions may have specific guidelines that require more frequent testing, particularly if the cylinder is used in harsher environments or environments where it may suffer from damage more frequently.

Maintaining this testing schedule helps prevent accidents and ensures that divers can rely on their equipment. Regular inspections, along with adherence to the testing intervals, contribute significantly to diver safety and the longevity of scuba gear.
