A tested pull is generally a used part removed from equipment and represented as having passed some test. The phrase is not a standardized medical-device condition grade. Its value depends entirely on what was tested, under which conditions, by whom, how recently, and what documentation and warranty support the result.
Key takeaways
- Tested pull does not define a universal test method.
- A successful power-on check is not the same as full functional, calibrated, or load testing.
- Ask for source, test scope, result, identifiers, warranty, and return terms.
01
Possible meanings
At the low-information end, the seller may know only that the source machine powered on. At the stronger end, the exact assembly may have been exercised in a compatible system, passed available diagnostics, and had results documented before removal. The listing phrase alone cannot distinguish these cases.
02
Questions to ask
Was the part tested before or after removal? On what system model and software? Which functions, operating modes, loads, channels, and interfaces were checked? Were errors present? Is there a test date, technician record, image, log, or report tied to the serial number? Was the source system deinstalled for upgrade, damage, or unresolved fault?
03
Limits of bench testing
Some parts cannot be fully evaluated without the intended system, calibration fixtures, known loads, environmental conditions, or long-duration operation. A board can pass a basic test yet fail intermittently under heat. A detector can communicate while still having image defects. Good suppliers state the limit of their test coverage.
04
Use condition language carefully
Do not treat tested pull, refurbished, repaired, as-is, and new-old-stock as interchangeable. Put the represented condition, test scope, warranty, return window, and acceptance plan in writing. Your facility still owns the decision and required return-to-service verification.
