Purpose: To present methods which@ according to the consensus of the aviation propulsion community represented by SAE Committee E-34@ allow the continued assessment of load carrying capacity of current chemistry products during periods of limited or nonavailability of previously used standardized methods. Field of Application: The methods listed in this document are intended to provide a means of generating data which can be used as a guide for making decisions against the backdrop of load capacity databases (Ryder@ IAE@ FZG) and experiences available on chemically similar oils used for lubrication of aircraft propulsion and power drive systems.
