    • Flammability Test Data in Risk Assessment 

      Deleanu, Lorena; Buzoianu, Dragoș; Crăciunoiu, Ștefan; Rîpă, Minodora; Spânu, Constantin (Universitatea ”Dunărea de Jos” din Galați, 2008)
      This paper reviews the most recent information on standards dealing with testing fire-resistance of hydraulic fluids in order to emphasis the importance of selecting hydraulic fluids including as basic criteria of reducing ...

    • Influence of Shear Stability on Oils Behaviour 

      Ciortan, Sorin; Rîpă, Minodora; Chiculiță, Simona (Universitatea ”Dunărea de Jos” din Galați, 2008)
      The paper presents a method to establish a link between the shear stability index and service behaviour of motor oils. A standardized method for shearing stability establishing is combined with appropriated curve fitting ...

    • Shear Stability as Oils’ Performance Indicator 

      Ciortan, Sorin; Rîpă, Minodora; Chiculiță, Simona; Spânu, Constantin (Universitatea ”Dunărea de Jos” din Galați, 2008)
      The paper presents a comparative analysis between the shear stability tests results and four ball tests results for some industrial oils. This correlation is used for establishing the way how the mechanical solicitations ...

    • Study of Wear Evolution for a Hydraulic Oil Using a Four Ball Tester 

      Spânu, Constantin; Rîpă, Minodora; Ciortan, Sorin (Universitatea ”Dunărea de Jos” din Galați, 2008)
      Time is crucial for the wear of materials. Time of an experiment must be long enough to obtain an observable wear but no so long to make the experiments expensive. For determining anti-wear properties of the hydraulic oils ...
