After how many years may a refrigerant recovery cylinder be used without needing to be re-tested?

A refrigerant recovery cylinder can be used for a maximum of five years without needing to be re-tested. This requirement is put in place to ensure safety and reliability in handling refrigerants, which can be hazardous. After this period, the cylinder must be re-certified to ensure that it maintains the necessary structural integrity and does not pose any risk during operation.

This five-year interval is standard across various safety regulations and guidelines adopted by the industry to minimize the risk of leaks, ruptures, or other failures that could occur if the cylinder were used beyond its tested timeframe. Following this regulation helps technicians and users ensure that equipment is not only compliant with safety standards but also effective in performing its intended functions.
