Lubricants, industrial oils and related products. Determination of the foaming and air release properties of industrial gear oils using a spur gear test rig. Flender foam test procedure Ingestion-build-279162 5 Constructional requirements1 Scope This International Standard describes a test method based on a single stage spur gear rig to determine the foaming properties of oils used for the lubrication of gears. This method is used for evaluating the foaming and air release properties of lubricating oils, in conditions close to real gearbox conditions.
