Refurbishment & Grading
A rebuilt device is only worth what its documentation says it is.
Parts strategy, reconditioning standards and the language that describes a rebuilt unit honestly — the part of the pre-owned market where claims outrun evidence.

- Grading language that holds up
Decide the parts strategy first
OEM and third-party parts produce different prices, different warranties and different clinical risk.
OEM versus third-party
OEM parts bring the manufacturer’s warranty and a known specification; third-party parts bring cost and availability, with the traceability burden on the refurbisher. The choice is defensible either way when the part is specified and the record is kept.
What must be replaced rather than inspected
Consumable-path components, seals, batteries and any part with a defined service life should be replaced on a rebuild rather than inspected and passed. A rebuilt device that reuses a life-limited part is a warranty claim waiting for a date.
Reconditioning standards and testing
The standard defines what was done; the test record proves it was done to that standard.
Define the standard in writing
Which parts are replaced, which are tested, what the acceptance criteria are and who signs it off. Without a written standard, every rebuilt unit is a one-off, and the next buyer has no way to compare it with anything.
Testing after rebuild
Functional test against specification, electrical safety test, and a burn-in or performance run where the device supports one. The burn-in is what catches the assembly fault that a functional test at the bench never sees.
Describe the device honestly
Grading language is what the buyer relies on when they cannot inspect the unit themselves.
Grading a rebuilt unit
Record the cosmetic grade, the functional grade and the refurbishment standard separately, and state which parts are new. A single adjective covering all three is what produces disputes, because each party reads it against a different standard.
Second life and sustainability claims
Reuse and remanufacture are increasingly part of procurement scoring, which makes them worth documenting properly. A sustainability claim without a refurbishment record invites the audit that follows every green procurement statement.
Four things a rebuilt device must carry
Without all four, the word refurbished is a description of intent.
A written standard
Which parts are replaced, which are tested, and what acceptance means.
A parts record
OEM or specified third-party, with the source recorded for each replaced item.
Test evidence
Functional and safety tests after rebuild, plus a burn-in where the device allows it.
Separate grades
Cosmetic and functional recorded independently, so the buyer knows what they are comparing.
