Cylinder Hydrostatic Test (Water Jacket Method) Hydrostatic testing is the most common way to check a SCBA cylinder for leaks or flaws. The test involves filling the SCBA cylinder with a liquid, usually water, which maybe dyed to aid in visual lead detection, and pressurization of SCBA cylinder to specified test pressure. Using this test helps maintain safety standards and durability of a SCBA over time. Test method and visual inspection guideline according to Compressed Gas Association (CGA). Pass/Fail with percentage (recorded TOTAL EXPANSION & PERMANENT EXPANSION). World’s recognize testing equipment. Widely used around the world (GALISO) Visual inspection according to CGA Pamphlets-more than 12 defects need to inspect. Has recorded data – Expansion, Test Pressure, Pass/Fail Percentage. Digital gauge and digital weighing scale (more persice). Has to calibrated the system before start the test (Calibrated Cylinder).
