Hydrostatic Testing

Philippine Sea (June 17, 2006) - Aviation Boatswain's Mate 3rd Class Larry Barron, left, and Aviation Boatswain's Mate Airman Matthew Hutchens prepare fire hoses for a hydrostatic test that will determine the accurate water pressure and integrity of each hose aboard the Nimitz-class aircraft carrier USS Ronald Reagan (CVN 76). Ronald Reagan and Carrier Air Wing One Four (CVW-14) are currently on a regularly scheduled deployment in support of the global war on terrorism and maritime security operations (MSO) and participating in Exercise Valiant Shield 2006. Valiant Shield focuses on integrated joint training among U.S. military forces, enabling real-world proficiency in sustaining joint forces and in detecting, locating, tracking and engaging units at sea, in the air, on land and cyberspace in response to a range of mission areas.

A hydrostatic test for a fire extinguisher is a National Fire Protection Association requirement. The full inspection and certification schedule is:


  1. 30-day physical inspection conducted by the owner for all types of extinguishers,
  2. An annual maintenance certification for all fire extinguishers (recharge if needed)
  3. A six-year comprehensive breakdown and recharge
  4. 12-year breakdown, hydrostatic test, and recharge


The hydrostatic test makes sure that the internal strength of the fire extinguisher is within specifications and that the container does not leak. Some fire extinguishers lose their ability to withstand pressure under the load in which it was designed. This can be caused by environmental effects such as weather, abuse and/ or vandalism or just the age of the fire extinguisher. For the majority of fire extinguishers a water jacket test is utilized for the hydrostatic test and official re-certification.
