1 Scope
This document describes methods for determining the consistency of lubricating greases and petrolatum by cone penetration.
This document is applicable to lubricating greases and petrolatum (vaseline).

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
penetration
depth that a standard object, cone or needle penetrates into a test portion under standardized conditions of time, temperature, load, etc
3.2
cone penetration
distance that a standardized cone penetrates into a test portion under standardized conditions of load, time and temperature
Note: The cone penetration is expressed in units of 0.1 mm.
3.3
working
shearing action of a grease worker
3.4
unworked penetration
cone penetration (3.2) of a test portion that has received only minimum disturbance in transfer from the sample container to the cup of the grease worker
3.5
worked penetration
cone penetration (3.2) of a test portion after it has been subjected to a defined number of strokes in a grease worker
3.6
prolonged worked penetration
cone penetration (3.2) of a test portion which has been worked more than the defined number of strokes in worked penetration
3.7
block penetration
cone penetration (3.2) determined on a test portion which is sufficiently hard to hold its shape without a container
