This standard guide pertains to removal and analysis techniques to remove debris captured by in-service lubricant and hydraulic filters. This standard guide suggests standardized methods to remove, collect and analyze debris from filters in support of machinery health condition monitoring. Debris removal techniques range from manual to automated. Analysis techniques vary from visual, particle counting, microscopic, x-ray fluorescence, and atomic emission.
Filter debris analysis has been in use for decades. The past decade has seen more widespread use due to the increased use of finer filtration resulting in a decrease in traditional Atomic Emission detection of wear debris. The US military and other militaries around the world as well as Original Equipment Manufacturers have adopted FDA techniques. Commercial in-service oil laboratories are also using a wide range of FDA techniques, from manual to automated. This standard guide will be used by in-service laboratories (commercial and military).
