Aren 6351-T6 cylinders properly inspected as part of the hydrostatic test?
Effective January 1st 2007, the DOT now requires 6351-T6 cylinders receive a combined visual and eddy current examination as part of the hydrostatic test. However, the DOT has not clearly established a training and inspection standard for combined visual and eddy current examination; they leave it to each facility to determine their own specific procedures. If you have a 6351-T6 cylinder that has a hydrostatic test within the last calendar year, AND you can provide documentation that the DOT testing facility also performed a combined visual and eddy current examination to PSI standards, our Fill Station Operators at their personal discretion may elect to fill the cylinder.
