smoke test



  • A test using a nontoxic, visible smoke to determine the routes taken by air currents and/or to detect leaks.


  • A test performed on a component, circuit, printed circuit, device, piece of equipment, or system. In it, the item in question is powered on, or otherwise put into operation, and if any smoke is visible the test is failed. The observation of sparks or other such electrical effects also constitute a failed test.
