Revision of D4289-21 Standard Test Method for Elastomer Compatibility of Lubricating Greases and Fluids

Rationale

Discussion of D4289 “Standard Test Method for Elastomer Compatibility of Lubricating Greases and Fluids” was also held with Dr. Fish presenting updated diagrams to address negatives which were found to be persuasive in the most recent balloting of this method. Once he has finalized these new figures, he will supply the chair with 5 ballot final items which the chair will then submit to ASTM.
Additional discussion of D4289 is still needed as some items still need to be reballoted to correct errors or to address concerns of voters with regard to those particular items. Items of concern included references to SAE elastomer materials and the use of mean vs median in final calculation of results. The chair will put time on the agenda at the December meeting for Dr. Fish to discuss status
