Cylinder Testing for Scuba Diving and Air Gun Cylinders is required periodically for all compressed gas bottles. This comprises of hydrostatic testing (hydro) and valve service every 5 years from the date of manufacture or if a visual test date has been missed. 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 Cylinders for charging air guns/rifles require a visual test within 5 years of manufacture. If a visual test is missed, a hydrostatic test is required. To meet the regulations for being an Air Gun Charging Cylinder, the cylinder valve must be fitted with 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 Cylinder Testing for Scuba Diving and Air Gun Cylinders will have an air, nitrox or trimix fill cost added at time of booking. For 232 bar single cylinders this is £5 for 300 bar cylinders this is £7.50.
