1.1 These test methods cover four procedures for measuring the consistency of lubricating greases by the penetration of a cone of specified dimensions, mass, and finish. The penetration is measured in tenths of a millimetre.

Note 1: The National Lubricating Grease Institute (NLGI)2 classified greases according to their consistency as measured by the worked penetration. The classification system is as follows:
