  1. Radiographic inspection may be performed at any point during the test sequence shown in this chart.
  2. Radiographic inspection rejects not to be counted for lot failure.
  3. Measurement of parameters for the purpose of drift value measurements need not be repeated for electrical measurements at room temperature.
