A contractor finds an inexpensive recovery machine online with no laboratory listing and no certification label anywhere on it. What does Section 608 require of recovery equipment used on the job?
- AIt must be rebuilt by the original manufacturer at least every five years at the factory
Manufacturers publish maintenance intervals and good practice includes changing oil and filters, but no federal rebuild cycle exists as a condition of putting a recovery machine to work.
- BIt must be registered with the certifying program that issued the technician credential before use
Certifying programs issue credentials to people. They have no role in approving hardware, and no registry ties a recovery machine to the technician who happens to own it.
- CIt must carry a state weights and measures seal showing its rated recovery capacity in pounds
Weights and measures programs cover commercial scales and fuel dispensers. Refrigerant scale accuracy matters in the shop, but no state seal certifies a recovery machine's performance.
- It must be certified against EPA performance standards by an EPA-approved testing organization
Why D is correct
Third-party testing is what proves a machine can actually pull the levels the rules require. EPA approves the testing organizations, those organizations test the equipment models against the performance standards, and the resulting certification is what makes the machine legal to use.
What this question is testing
This checks whether the candidate knows that recovery equipment carries its own certification requirement and that the approval comes from an EPA-approved third-party testing organization. The distractors borrow language from maintenance schedules, technician programs, and state agencies to see whether the candidate can name the correct authority.
On the job
Auction and marketplace machines are a real temptation when a recovery unit dies mid-season. The problem is proving compliance later: if the nameplate is gone and the manufacturer never listed the model with a recognized laboratory, an inspector has nothing to verify. Buy from a supply house, keep the manual, and photograph the data plate before it wears off. It also matters for refrigerant type, since a machine approved for one group of refrigerants is not automatically fit for another.
Memory technique
No label, no legal. If the machine cannot show who tested it, it does not belong on the truck.
Exam tip
Recovery equipment answers should point at an EPA-approved testing organization. Rebuild cycles and state seals are invented distractors.
Where to look it up
Recovery and recycling equipment must be certified by an EPA-approved testing organization to meet EPA performance standards.
