What is the hydrostatic testing frequency for scuba tanks?

Hydrostatic testing is a critical procedure for ensuring the safety and integrity of scuba tanks, which are used to store high-pressure gases. The accepted standard for hydrostatic testing frequency is every five years. This time frame allows for sufficient monitoring of the tank's structural integrity while ensuring that any potential issues can be identified and addressed in a timely manner.

During the hydrostatic test, the tank is filled with water and pressurized to check for leaks or signs of weakness that could fail under operational pressures. Adhering to the five-year interval is vital for maintaining safety since tanks can degrade over time due to corrosion, fatigue, or other factors, especially if they are used frequently or stored improperly. Regular testing helps ensure that divers are using reliable equipment, minimizing the risk of catastrophic failure during dives. This interval aligns with guidelines set by organizations such as the Department of Transportation (DOT) in the United States, reinforcing the importance of compliance for all scuba tank users.
