Federal law requires that refillable cylinders used to recover refrigerant must be inspected and hydrostatically tested a minimum of
once every five years
in accordance with 49 CFR Part 180, Subpart C or as specified in an applicable Special Permit as provided by the manufacturer of the cylinder.
How often should refillable cylinders be hydrostatically tested?
The markings are normally stamped into the shoulder of the cylinder. The hydrostatic test date and inspector mark indicate when the cylinder was last tested and who tested the cylinder. Most cylinders are required to be tested
every 5 years
. This test ensures the cylinder can safety hold the maximum fill pressure.
How often do refrigerant cylinders need to be tested?
Refillable cylinders must be retested and recertified
every five years
, with the test date stamped on the cylinder shoulder in accordance with DOT regulations. A test to see if it will hold air pressure by your local LP company does not count.

Why should you avoid mixing refrigerants?
Mixing refrigerants can
have an adverse effect on air conditioning and refrigeration systems
, resulting in reduced efficiency, performance, and longevity. And it can create a safety hazard for the technician who may not know exactly what type of refrigerant a system may contain.
What refrigerants do not need to be recovered?
Co2 refrigerant R-744 (Carbon dioxide)
is a very high-pressure refrigerant and generally does not need to be recovered.
How much refrigerant can you put in a recovery cylinder?
To prevent overfilling, recovery cylinders should not be
filled to more than 80 percent of their internal volume
. Most technicians accomplish this by placing the recovery cylinders on an electronic scale and monitoring the weight of the cylinder during the recovery process.
When can you use a disposable cylinder to recover refrigerant?

at least 20 feet (6.1 m) from highly combustible materials
such as oil or excelsior. Cylinders should be stored in definitely assigned places away from elevators, stairs, or gangways.
Can a recovery cylinder be filled to 100 percent capacity?
Next, look for a stamp that says WC. This value indicates the tank’s water capacity, the
total
weight in liquid water to fill the tank 100%. You cannot fill above 80% with liquid, or you risk building up the hydrostatic pressure and exploding the tank.
Does refrigerant expire?
Theoretically,
Freon can last forever
. It is not burned up like fuel. When an air conditioning system is in top shape, the refrigerant will be continually recycled within a closed system, to cool your home.
Does R 22 go bad?
As we approach 2020, R22 (Freon)
will be set to expire or use in the USA
. … The US Environmental Protection Agency has set the date of January 1, 2020, for R22 to longer to be manufactured or imported in the US. This poses a problem for how this will impact your commercial HVAC system.
