Hydrostatic Testing
The Department of Transportation (DOT) requires a hydrostatic test on all solid-walled scuba cylinders every five years. Dive Quarters can perform required hydrostatic testing on other cylinders such as industrial, SCBA and paint ball bottles. Most fiber-wrapped bottles require testing every three years. There are some exceptions for paint ball bottles. Please consult staff for more details.

This test requires that we fill cylinder with water, immerse it in water and pressurize it to five-third’s of its working pressure to determine the elasticity of the cylinder walls. The cylinder is allowed to expand up to 10 percent. If it expands more than 10 percent, or it physically fails in the testing process, it is removed from service. Current policy requires the test facility to stamp it “condemned” and stamp out the DOT information. The cylinder will then be returned to the customer. If the cylinder passes, a date stamp in the shoulder of the tank will record the tank as having passed.

Visual Inspections
This is an examination of the cylinder, internally and externally, for corrosion or damage.  If it is determined that a cylinder needs servicing, Dive Quarters can provide the appropriate services to bring the cylinder to industry standards. DOT requires a visual inspection on solid-walled scuba cylinders every time a tank is hydrostatically tested, as well as once a year. All other cylinders require visual inspection only during hydrostatic test. Once determined passable, a sticker on the tank will record the tank as having passed.

Visual Eddy Current Inspections
This form of non-destructive testing using an Eddy current, looks for cracks or imperfections in the neck of aluminum cylinders. All cylinders manufactured by Luxfor before 1990 require an Eddy current test every five years in addition to their five-year hydrostatic test because there has been sustained stress crack loading around the threaded valve connection and neck of pre-1990 Luxfor aluminum cylinders. All other manufacturers of aluminum tanks used a different alloy and are not required to be Eddy current tested. As of January of 1990, Luxfor changed the alloy in their aluminum tanks to match the same standard of other manufacturers.

Fill Policy
Only currently employed Dive Quarters trained staff will fill tanks in accordance with industry and DOT standards. Before filling, the staff member will ensure the cylinder is up to date and current on its visual and hydrostatic tests by looking for current hydro stamps and visual stickers. If it is a Nitrox or pure oxygen fill, they will verify proper level of oxygen cleanliness and proper credentials to receive the fill. We would be happy to fill your cylinders while you wait if staff is available. If you leave cylinders off for fill, contact information must be clearly marked on the tank(s). All Nitrox fills are a multi-step process using a partial-blend technique. A quality fill requires an adequate amount of time to complete. A two-hour minimum is required for each fill. Be aware that other tanks may be ahead of yours for filling and plan accordingly.
