Scope

This document specifies a method for evaluating the change of consistency, as measured by cone penetration, of lubricating grease when worked in the roll stability test apparatus, in presence of water. The method only applies to greases with cone penetration in the range 175 1/10 mm to 385 1/10 mm as measured using ISO 2137.

Purpose

The purpose of this document is to prescribe a method for the evaluation of the behaviour of a grease when it is rolled in presence of water by the evaluation of the consistency change, and hence to predict its mechanical behaviour, the risk of leakages due to excessive softening, the risk of lubricating properties losses by excessive hardening or complete solubilisation.
