    Rationale

    Used oil sample preparation for D664, D4739 and D7946 test methods have previously been revised to be equivalent. This work item seeks to align the used oil sample preparation guidelines in D974 with these other test methods. Comparable sample preparation allows a portion of test sample to be shared among these test methods without further treatment.
