Evaluate in an actual vehicle degas bottle, or other container as approved by the jury. Jury may consist of the appropriate Materials Engineering Activity, the Responsible Engine Coolant Engineering Activity, Vehicle Design and Release Engineers and Laboratory Personnel. The pellet supplier should keep internal standards from these samples to use for quality control purposes.
