Materials and methods

Test guideline
Qualifier:
according to
Guideline:
OECD Test Guideline 114 (Viscosity of Liquids)
Principles of method if other than guideline:
At atmospheric pressure the kinematic viscosity was measured with a Ubbelohde-type glass capillary-tube viscometer in a thermostated bath. Thereoff the dynamic viscosity was calculated by multiplication of the density at atmospheric pressure.
GLP compliance:
not specified
Type of method:
capillary viscometer (static)

Applicant's summary and conclusion

Conclusions:
The dynamic viscosity of diethyl carbonate was determined to be 0.81 mPa x s at 20°C and 1000 hPa.
Executive summary:

At atmospheric pressure the kinematic viscosity was measured with a Ubbelohde-type glass capillary-tube viscometer (OECD Test Guideline 114: Viscosity of Liquids). Thereoff the dynamic viscosity was calculated by multiplication of the density at atmospheric pressure. The dynamic viscosity of diethyl carbonate was determined to be 0.81 mPa x s at 20°C and 1000 hPa.
