Hydrostatic Pressure Testing of CO2 Fire Extinguishers

Hydrostatic pressure testing is a method used to ensure the safety and reliability of CO2 fire extinguishers by checking the strength and integrity of the cylinder. The test involves filling the cylinder with water and applying increasing pressure to it until the desired test pressure is reached.

The cylinder is then inspected for any leaks, cracks or deformations. The test pressure is typically about 5/3 times the working pressure of the extinguisher, and the test should be performed periodically as per industry standards.
