This method describes a gravimetric procedure for the determination of solid particle contamination in packaged aircraft turbine lubricants and related fluids. This method is Federal Test Method 791, Method 3010 used in Aerospace Standard 5780.
Rationale: This SAE Aerospace Recommended Practice is intended to provide acceptable procedure for qualification purposes to determine the tendency of aircraft lubricating oils to oxidatively degrade at elevated temperatures and pressures into products that form suspended fine carbon particles under engine conditions. Properties of such particles may cause filters and other fine passages in the lubricant system to clog.
