Abstract:
Lubricating greases are critical for reliable mechanical performance under extreme conditions. Standardized rheological testing is essential to characterize their viscoelastic and temperature-dependent behavior. In this study, greases of various National Lubricating Grease Institute (NLGI) grades were evaluated using an Anton Paar Modular Compact Rheometer (MCR) equipped with a Peltier Temperature Device (PTD), in accordance with DIN 51810. Part 1 measured shear viscosity of NLGI grade 1 grease; Part 2 assessed yield and flow points of grades 0–2 at +25 °C and –40 °C; Part 4 determined consistency of metal-saponified greases. Results confirm the Anton Paar MCR with PTD as an accurate, reproducible, cost-effective tool for grease classification.
