At what interval must refrigeration cylinders be re-tested?

Refrigeration cylinders are required to be re-tested every five years to ensure their safety and structural integrity. This testing process is crucial because it helps prevent potential leaks and accidents that could occur due to wear, corrosion, or other damaging factors over time. The five-year interval is established to strike a balance between ensuring safety and practicality, allowing for periodic checks while not imposing excessive burdens on operators. Regular re-testing helps maintain compliance with safety regulations and environmental standards, ensuring that equipment remains reliable and minimizes the risk of refrigerant release, which can be harmful to the environment.
