Any other information on results incl. tables

The measured result was kinematic viscosity based on the calibration constant of 0.002545 centistokes per second. The result for dynamic viscosity was obtained by multiplying the kinematic viscosity with the density of the compound (1.589 g/mL). The density was obtained from the measured specific gravity of the compound. Only the dynamic viscosity result of 2.43 mPa∙s (cP) at 23 °C was reported. It is unknown if the the study follows an OECD, ASTM, or ISO guideline.

Applicant's summary and conclusion

Conclusions:
The viscosity of MeDONA is 2.43 mPa∙s at 23 °C.
Executive summary:

The kinematic viscosity of MeDONA was measured using a Schott AVS350 viscosity timing system with a Schott Ubbelohde-type glass capillary viscometer, type 545-03. Temperature was controlled using a Haake DC3 bath circulator/controller. Using the kinematic viscosity and density results, the dynamic viscosity of MeDONA at 23 °C was determined to be 2.43 mPa∙s (cP) at 23 °C. The study was performed using a calibrated Ubbelohde-type capillary viscometer. These types of viscometers are compliant with ASTM D445 and ASTM D446 standards. However, it is unknown if this study followed an ISO, ASTM, or OECD guideline. The study was not conducted in accord with GLP guidelines. Therefore the study is classified reliable with restrictions.
