there is also a regulation

The Department of Transportation (DOT) has had regulations covering the retesting of reusable cylinders for the past 40 years. These regulations predominantly cover the large (100-lb and above) cylinders that are used for virgin refrigerants.

But there is also a regulation covering smaller (30- and 50-lb water capacity) cylinders used in refrigerant recovery.
