The NLGI consistency number (sometimes called “NLGI grade”) expresses a measure of the relative hardness of a grease used for lubrication, as specified by the standard classification of lubricating grease established by the National Lubricating Grease Institute (NLGI). Reproduced in standards ASTM D4950 (“standard classification and specification of automotive service greases”) and SAE J310 (“automotive lubricating greases”), NLGI's classification is widely used. The NLGI c… WebCone penetration measures the consistency or cohesiveness of grease by dropping a cone of known mass into a grease filled trough and recording the penetration depth of the cone. A low depth of penetration indicates stiff grease. The adherence of grease to the substrate is characterized by water spray-off or water wash-out measurements. 11
