ASTM D2596 PDF
Seta-Shell Four Ball Autoload Lubricant Tester for ASTM D, ASTM D, IP We perform grease testing by ASTM D to measure the load-carrying properties or load wear index of lubricating grease using a four ball test apparatus. This standard is issued under the fixed designation D ; the number 1 This method is under the jurisdiction of ASTM Committee D02 on Petroleum.

Seven tests for selecting the right grease Greases are used to overcome real-world problems presented by operating environments and operating conditions of mechanical equipment.
The problems can be characterized in d25596 main categories: Force applied to a bearing or journal that exceeds the load carrying capability of the grease. The result is metal-to-metal contact, premature wear and increased heat.

The result is breakdown of grease, cold welding or galling. Mud, water and steam can wash away grease, leaving metal unprotected. Dust, dd2596 and abrasive particles can combine with grease and grind away metal. Acids, caustics and cleaning solutions can break grease down and corrode metal.

How do you know if the grease you are using is right to protect against harsh environments AND routine operating wear. How do you know what grease will work best at protecting your equipment? The answers are in a few ASTM test methods. D What the test measures: Result values and what they mean: Results are reported in kilograms kg with a functional range from kg to kg.
The higher the number the greater load-carrying ability.
Determines the load-carrying properties of lubricating greases by measuring scaring on a test specimen. Scar size is measured on a test specimen.

The lower the mm, the more protection a grease provides. Dropping point ASTM test: Determines the temperature point at which grease changes from a semi-solid to a liquid. Water washout ASTM test: Determines resistance of a lubricating grease to washout by water Result values and what they mean: Results are reported as percentage with a functional range from 0.
The lower the percent weight loss the less likely the grease will wash out. Oxidation stability ASTM test: Determines resistance of lubricating greases to oxidation and helps determine shelf life of grease.
Results are reported as pressure loss expressed in pounds per square inch psi with a functional range from 0 to psi.
The lower the number, the less likely the grease will oxidize and the asm it will last on the shelf. Penetration ASTM test name: Determines a d596 ability to withstand repeated mechanical stress. Results are reported as percent change expressed in whole numbers with a functional range from 0 to percent.
The lower the percent change, the greater the mechanical stability of the grease. What the test measures: Determines the strenghth of the boundary film between metal surfaces that provides extended protection.
awtm Results are reported in weight percent expressed in whole numbers with a functional range from 1 to percent. The higher the number, the greater the long-term protection. Making sense of it all–how to pull it together in a simple and understandable form The Leon-Maxwell Equation simplifies the lubricant selection process.
The equation combines several ASTM test methods and satm that best represent performance. The equation normalizes the results and produces a value that can be used in the selection, application and consolidation process from typical to extreme environments. The higher the L-M score, the more applications the grease will provide lube protection. The Leon-Maxwell number is an excellent method to quickly and accurately evaluate a grease protection potential and as an indication of a greases ability to be used in a wide variety of applications.
This becomes astn when maintenance teams are trying to reduce the number of greases that are being purchased.
