Significance & Use

Cone penetration test results provide one measure of the consistency of Grease. With the help of the grease worker, the worked penetration results are determined. These worked penetration results are required to determine to which NLGI Consistency grade a grease belongs. Undisturbed penetration results provide means of evaluating the effect of storage conditions on grease consistency.
