ASTM D937 standard test method for cone penetration of petroleum
1. Scope
1.1 This test method covers measuring with a penetrometer the penetration of petrolatum as an empirical measure of consistency.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Terminology
3.1 Definitions:
3.2 penetration of petrolatum - the depth, in tenths of a millimetre, that a standard cone will penetrate the sample under fixed conditions of mass, time, and temperature.
3.3 penetrometer, n - an instrument that measures the consistency or hardness of semiliquid to semisolid materials by measuring the depth to which a specified cone or needle under a given force falls into the material.
3.3.1 Discussion - In this test method, a standard penetrometer cone (see Test Methods D217) is used to determine the consistency of petrolatum. The penetration force is determined by the total mass of the cone and shaft.
