Kinematic Viscosity Test (ASTM D445)
It is the test where the resistance of oils against flow, in other words the fluidity, is determined. It is measured at 100 °C for applications in the automotive industry. Its unit is mm²/s or cSt.
Viscosity Index (ASTM D 2270)
It is the test that determines the change in temperature and viscosity values of oils. As the Viscosity Index increases, the viscosity decreases less with temperature increase.
Pour Point (ASTM D 87)
It is the test that determines the final temperature at which oils can flow. It is an important test especially in terms of storage and working environment temperature.
It is the test that determines the flaming and burning temperature values of oils. These values are important for operational safety.
Total Base Number
It is the test method where the basic component quantity in the structure of oil is determined. The acids formed by fuels are neutralized by basic components contained in engine oils. Therefore it is an important parameter.
Cold-Cranking Simulator (ASTM D 5293)
It is a test method where the apparent viscosity of engine oils at low temperatures is determined. It is important in terms of showing the cold performance of engine oils.
Borderline Pumping Temperature (ASTM D 3829, ASTM D 4684)
It is the test that determines the lowest temperature value in which the engine oils can be pumped sufficiently and continuously.
Evaporation Loss (ASTM D 5800)
It is the test that determines the % of evaporation loss value of engine oils.
