How often must SCUBA cylinders be hydro tested?

SCUBA cylinders must be hydrostatically tested every 5 years to ensure their integrity and safety. This testing procedure checks for any weaknesses or damage that could lead to catastrophic failure under pressure. The 5-year interval is established based on industry standards and regulations, which aim to ensure safety for divers using these cylinders.

Hydro testing involves filling the cylinder with water and pressurizing it to a specified level, allowing examiners to detect any leaks or deformations. The process also verifies that the cylinder’s material and structure are sound. Following this schedule helps to maintain equipment reliability and protect divers from potential hazards associated with using defective tanks.

While there are other intervals for different types of tanks and regulations in various contexts, specifically for SCUBA diving cylinders, the 5-year frequency is recognized across the diving industry. Regular maintenance and testing are crucial, but they are not performed more frequently than this given period for standard SCUBA cylinders.
