    Penetration tests are performed on petroleum products to determine consistency and shear stability (lubricating greases) for design, quality control and identification purposes. A standard cone or needle is released from a penetrometer and allowed to drop freely into the sample for 5 seconds (or a different specified interval) at constant temperature. The depth of penetration of the cone or needle into the sample is measured in tenths of a millimeter by the penetrometer.

    The Air Jet Erosion Test Rig has been developed to evaluate the erosion resistance of variety of materials and conforms to the specifications of ASTM G76 standard. The principle of operation consists of subjecting the test sample to a jet of air carrying the erodent, through a tungsten carbide nozzle of a known diameter. The impingement of the erodent particles on the test sample surface causes erosion and this is quantified by weight loss method. The particle velocity is controlled by varying the flow rate of air and the erodent feed rate is varied by changing the speed of the conveyor system which delivers the erodent to the jet of air. The particle velocity is measured with a well-established Double Disc arrangement method. The test sample temperature can be varied from ambient to 4000C and test sample inclination is infinitely variable 0-900 with respect to the jet of erodent particles.

    The Grease Noise Tester evaluates the lubrication integrity of greases, providing a quantitative assessment of the noise characteristics of the grease. The use of clean lubricants is essential for obtaining long bearing life. A clean grease for initial lubrication as well as re-lubrication are essential to ensure machine longevity. In applications where bearing fatigue life is not critical such as low operating loads, a clean grease is essential to ensure low bearing noise required for many electric motor applications.
