Cylinder Hydrostatic Testing Overview. The myth busters demonstrated that what happened to Jaws could happen to anything or anyone in proximity to a compressed gas cylinder … Pressure cylinders must be inspected and tested at specific intervals to ensure that no conditions exist that preclude the cylinder from performing to its next inspection interval. Do you remember when Jaws lost its appetite when a SCUBA cylinder failed the gunfire test? The Pipeline and Hazardous Materials Safety During a hydrostatic requalification test, the cylinder is examined to ensure it can safely hold its rated pressure. Hydrostatic testing should only be performed by trained, qualified persons. a. It is important to note that a failure of the cylinder to hold pressure means the extinguisher must be retired. A hydrostatic test involves pressurising the cylinder to its test pressure (usually 5/3 or 3/2 of the working pressure) and measuring its volume before and after the test. 2 A cylinder in chlorine or sulfur dioxide service made before April 20, 1915, must be retested at 500 psi. No matter what type of cylinders you use for your business, it’s important that they be properly tested to ensure they are in working order.
