Abstract
A kit for testing grease includes components for testing consistency, oil bleed characteristic and contamination. Consistency of the grease is tested by compressing a sample of the grease between two surfaces (e.g., glass plates), measuring the extent of spread, and comparing the measured spread to a calibrated reference. Oil bleed characteristic is tested by placing a quantity of the used grease on a test medium, heating the test sample, measuring a dimension of the grease quantity on the heated test sample, and determining the bleed characteristic of the used grease by comparing the dimension of the grease quantity to a reference. A contamination test may be performed by further compressing the consistency sample and inspecting the sample both by the naked eye and with a microscope.
