Hydrostatic testing of fire suppression system cylinders is a process used to verify the structural integrity and safety of the cylinders under pressure. It involves subjecting the cylinder to a pressure significantly higher than its normal operating pressure to detect any signs of weakness or leaks. The process begins with a visual inspection of the cylinder to check for any external damage, such as dents, corrosion, or cracks. Any cylinder with visible damage is typically rejected and not subjected to hydrostatic testing. The cylinder is then emptied of its fire suppression agent and connected to a hydrostatic test pump. The cylinder is filled with water, and the pressure is ....
