Oil Carbon Particulate Test
This method describes a test for determining the tendency of aircraft lubricating oils to oxidatively degrade at elevated temperatures and pressures into products that cause suspended fine carbon particles causing filters and other fine passages in the lubricant system to clog resulting in an unscheduled shutdown of the engine while in flight.
This method is cited in AS5780 with no documentation other than from the development company (Pratt & Whitney) and modifications (Air BP Lubricants).
