How often is the MK-20 surface supply system required to be hydrostatically tested?

The MK-20 surface supply system is required to be hydrostatically tested every 5 years to ensure its integrity and safety for use in diving operations. This testing schedule is part of the maintenance protocols established for diving systems to detect any potential weaknesses or failures in the equipment due to factors such as material fatigue or corrosion over time. By adhering to a 5-year interval for hydrostatic testing, operators can confidently ensure the reliability of the system during its operational lifespan, minimizing the risks associated with underwater activities. Regular testing is crucial for the safety of divers relying on this equipment, and the 5-year requirement reflects an industry standard that balances thoroughness with practicality.
