Scuba Diving and Air Gun Cylinder Testing


Ensuring Safety: Comprehensive Testing for High-Pressure Cylinders

Proper maintenance and periodic testing of high-pressure cylinders are critical to ensuring their safety and functionality. In the UK, regulations mandate that every high-pressure cylinder over 1 litre undergo regular testing. For cylinders used in SCUBA diving, the testing intervals and procedures are particularly stringent.

Mandatory Testing Intervals and Procedures

All high-pressure cylinders, regardless of their application, require periodic testing:

  • SCUBA Cylinders: These must undergo testing every 2.5 years. The type of test alternates between a hydrostatic test and a visual inspection, depending on the previous test and the cylinder’s specifications.
  • Surface-Only Cylinders e.g. Air Guns: Cylinders designed exclusively for surface use, which are not intended to go underwater, require testing every 5 years. These cylinders are always subjected to hydrostatic testing.

  • Oxygen Cleaning: Essential for cylinders used with 100% oxygen or enriched air, ensuring they are free from contaminants that could cause combustion.
