Spesifikasi KOEHLER K38500 Apparent Viscosity of Engine Oils
Alat Laboratorium Umum
Test Method
Determines the measurement of the Yield Stress, Apparent Viscosity and Borderline Pumping Temperature (BPT) of engine oils. Borderline pumping temperature is a measure of the lowest temperature at which an engine oil can be continuously and adequately supplied to the oil pump inlet of an automotive engine. Provides a correlation between the temperature at which the viscosity of engine oils reaches a critical value and the borderline pumping failure temperature in engines at the test method specified shear stress.
