Abstract:
Greases are primarily used to increase the mobility of an object against another. The viscosity of grease becomes high enough at low temperatures where it congeals and stops flowing. Currently, a few experimental techniques, such as the US Steel Grease Mobility, the Lincoln Ventmeter, and the Apparent Viscosity of Lubricating Greases (ASTM D1092) Methods are used to study low temperature properties of greases. DIN Method 51805, also called the Kesternich Method, has been used in Europe to gain a better understanding of low temperature properties of greases. In this paper, we study the development of a new instrument and procedure akin to the Kesternich Method. We evaluate a wide range of greases and compare their low temperature properties with the newly developed instrument and attempt to generate a new test procedure along with repeatability for this technique.
