Work Item s - proposed revisions of this standard. When this is completed, the technician repeats the cone test to determine the P60 value, also known as a worked penetration. The grease is then sheared or worked using a mechanical hand operated device through 60 double strokes, simulating the use of the grease.

The penetration is measured in tenths of a millimetre. Historical Version s - view previous versions of standard Work Item s - asgm revisions of this standard Translated Version s: Overview of the conductive grease range. The penetration is measured in tenths of a millimetre. Such greases usually have penetrations below eighty-five tenths of a millimetre.

Grease Penetration Test (ASTM D-217 and ASTM D-1403)

The higher the penetration value, the softer the grease. Synthetic Lubricants in Space. Lubricant Vapour Pressure test. Temperatures and other dimensions are given in the preferred SI units; the values shown in parentheses are provided for information. Such greases usually have penetrations below eighty-five tenths of a millimetre. So how to the penetration values equate to the NLGI grades?

Worked penetration results are atm to sstm to which NLGI consistency grade a grease belongs.

Link to Active This link will always route to the current Active version awtm the standard. Test Method D should be used for such products. Vintage Microscope Restoration-Case Study.

These values determine the stiffness of the grease and how a grease aetm react over time to service and wear. 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.

The latter are usually preferred for inspecting lubricating greases.

Work Item s - proposed revisions of this standard. When this is completed, the technician repeats the cone test to determine the P60 value, also known as a worked penetration.

A grease that is too soft may migrate away from the v217 that needs to be lubricated. Test Method D should be used for such products. In contrast, Test Method D is aimed at petrolatums and Test Method D uses less precise one-quarter and one-half scale equipment intended for use when the sample quantity is limited.

Undisturbed penetration results provide a means of evaluating the effect of storage conditions on grease consistency.

Grease Penetration Test (ASTM D and ASTM D) | Newgate Simms tech support

The technician records the depth in a tenth of a millimeter of this hole. In cases where equivalent SI conversions are not known, notes are added for clarification. Metric equivalency tables are provided with each figure. Electrically Conductive Grease introduction. 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.

Newgate Simms tech support. For base oil characteristics, Kinematic Viscosity testing is a key data point to understand.

An undisturbed penetration test, described in Appendix X1, is similar to the unworked penetration test. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Active view current version of standard. Understanding the Viscosity Index data point. Grease penetration tests are conducted by Nye technicians in order to determine the stiffness of a grease.

The penetration test begins with the grease at 25 degrees Celsius, plus or minus 1 degree Celsius, being levelled into a cup.
