Revision of D2983-19 Standard Test Method for Low-Temperature Viscosity of Automatic Transmission Fluids, Hydraulic Fluids, and Lubricants using a Rotational Viscometer


At the June 2019 meeting of D02.07.C, the Section agreed to ballot a new revision to D2983 regarding comments made by a negative voter on Ballot D02(19-02) to add automated Procedure D to Standard Test Method D2983. This ballot item addresses that voters concerns regarding Procedure D. In addition, there is concern about the viscous presence of gelation, which is the primary cause of automatic transmission failure at low operating temperatures, and is most evident at transmission fluid viscosities below 3000 mPas. The Section has decided to look into this further. The proposed note will reflect these concerns.
