Cylinder Testing

Scuba cylinders require hydrostatic testing (hydro) and valve service every 5 years from the date of manufacture.

A visual inspection (visual) and valve service is required within 2 ½ years from the date of manufacture or the last hydrostatic test. If the visual test is missed then the cylinder will require a hydrostatic test.

Air Gun Charging Cylinders require hydrostatic testing (hydro) and valve service every 5 years from the date of manufacture or if a visual test date has been missed. To meet the regulations for being an Air Gun Charging Cylinder, the cylinder valve must be a surface use only valve, ie must include gauge and pressure bleed.

Scuba cylinders which are used with an air gun charging adapter will fall under the same regulations as scuba cylinders, as they “can” be used underwater, even if this is not what you are using it for.

All cylinders are tested on-site in our workshop to BS EN 1968:2002, BS EN 1802, BS EN ISO 11623:2002, Bs EN 22434:2011, ISO 13769:2002 AND  IDEST CP11:2011.
