CONE PENETRATION OF LUBRICATING GREASE USING 1/4 AND 1/2 SCALE CONE EQUIPMENT.
This method covers two procedures for measuring the consistency of small samples of lubricating greases by penetration of a ¼-scale or a ½-scale cone. It is applicable to greases of National Lubricating Grease Institute (NLGI) Grades 0 to 4 and is intended for use only where the size of the sample limits the use of ASTM Method D217-IP 50, Test for Cone Penetration of Lubricating Grease.
