Research Report RR:D02-1646

    This ASTM Research Report combines data from two different studies supporting ASTM D7416-09. The more recent Reproducibility study involves testing thirteen different in-service lubricant samples through seven different five part integrated tester laboratories, each with a different operator. The earlier repeatability study involves testing two different in-service oil samples thirty times each in a single five-part integrated tester laboratory. All samples were tested using the multiple measurement sensors within the five part integrated tester. In addition to reporting of quantified measurements, diagnostic interpretation of that data is also reported in score values for wear status, contamination status, and chemistry status for the each sample data set.
