Abstract

A joint Working Group under the auspices of ELGI and NLGI is continuing to make good progress in defining a system for evaluating the size and number of particles in a grease sample. The group is working to evaluate robust methodologies for measuring these properties.  This joint working group gets together at both the NLGI and ELGI Annual Meetings in addition to other scheduled discussions throughout the year.  This group has been assessing the feasibility of combining the results from two test methods as a particle evaluation system: 

  • “Standard Test Method for Estimation of Deleterious Particles in Lubricating Grease” (ASTM D1404) is being evaluated as a potential indicator of abrasiveness or hardness of particulate matter.  This method uses acrylic plates to quantify the number of particles that will cause scratching and therefore provide an indication of the potential for these particles to cause damage.
  • The Hegman Gauge is being evaluated as a potential indicator of the number and size of the particles. “Standard Test Method for Fineness of Dispersion of Pigment-Vehicle Systems by Hegman-Type Gage” (ASTM D1210) is a current ASTM standard used to measure pigments in coatings which the group hopes to adapt for use with greases.

This webinar will discuss some of the background of this work, as well as the status of current testing including an update on an industry round robin currently underway.
