1.1 This test method covers the determination of the kinematic viscosity of aircraft turbine lubricants at low temperature, and the percent change of viscosity after a 3 h and a 72 h standing period at low temperature.
1.1.1 The range of kinematic viscosities covered by this test method is from 7700 mm²/s to 14 000 mm²/s at -40 °C and from 7000 mm²/s to 17 500 mm²/s at -51 °C. The precision has only been determined for those materials, kinematic viscosity ranges, and temperatures as shown in the precision section. Kinematic viscosities and percent change of viscosity may be measured and reported at other temperatures and other thermal soak period intervals as agreed by the contracting parties.
