Standard Test Method for Kinematic Viscosity of Volatile and Reactive LiquidsMore info
1.1 This test method covers the measurement of kinematic viscosity of transparent, Newtonian liquids which because of their reactivity, instability, or volatility cannot be used in conventional capillary kinematic viscometers. This test method is applicable up to 2 × 10−5 N/m2 (2 atm) pressure and temperature range from −53 °C to +135 °C (−65 °F to +275 °F).
1.1.1 For the measurement of the kinematic viscosity of other liquids, see Test Method D445. The difference between the two methods is in the viscometers. The viscometers specified in used Specification D446 are open to the atmosphere, while the viscometers in this method are sealed. When volatile liquids are measured in sealed viscometers, the density of the vapor may not be negligible compared with the density of the liquid and the working equation of the viscometer has to account for that. See Section 11 for details.
