A shop owner assumes the shop's recovery machines have to be sent away for recertification on a schedule, the way some measuring instruments are. What is actually required of certified recovery equipment over its working life?
Correct Answer
A) Nothing periodic, because certification attaches to the equipment as it was manufactured
Recovery equipment is certified as a design, tested by an EPA approved organization against the standard that applies to it, and that certification stays with the machine. There is no renewal cycle, no annual submission and nothing that has to happen when the machine changes hands. What the machine does need is ordinary maintenance, because a neglected recovery unit gradually loses the ability to reach the levels it was certified to reach. That is a performance question the shop manages, not a certification that expires.
Why This Is the Correct Answer
Recovery equipment is certified as a design, tested once by an EPA approved organization against the standard that applies to it, and that certification stays with the machine for its working life. There is no renewal cycle and nothing triggered by a change of ownership. What the machine does need is the manufacturer's routine maintenance, since a neglected unit slowly loses the ability to reach the level it was certified to reach.
Why the Other Options Are Wrong
Option B: Recertification every five years, matching the interval for cylinder pressure retesting
Five years is the periodic requalification interval for refillable cylinders, which are pressure vessels. Recovery machines have no equivalent recertification cycle.
Option C: Recertification each time the machine is sold or transferred to a different owner
Certification belongs to the equipment design and travels with the machine. A change of ownership does not affect it, although a buyer should confirm what the machine was certified for.
Option D: Annual recertification by the organization that approved the original design
There is no annual renewal. Testing organizations certify the model against the standard once, and the certification does not lapse with time.

Cylinders have a clock. Machines and people do not.
Reference Hint
Recovery equipment certification is granted to the design at manufacture and does not expire or require periodic renewal.
