Key result

Temp.:

20°C

Parameter:

kinematic viscosity (in mm²/s)

Value:

4.699 - 4.717

Remarks on result:

other: The kinematic viscosity at 20 °C is reported as 4.7 mm²/s

Any other information on results incl. tables

Dynamic viscosity calculated as kinematic viscosity x density:

4.7 * 1.80 = 8.46 Pa*s at 20 °C.

The kinematic and dynamic viscosities at 40 °C are 2.7 mm²/s and 4.77 Pa*s

Applicant's summary and conclusion

Conclusions:

The kinematic viscosity of TFEE-5 at 20 °C is 4.7 mm²/s

Executive summary:

The kinematic viscosity of TFEE-5 was measured using capillary viscometry in Cannon-Fenske Routine Viscometers. The kinematic viscosity of TFEE-5 at 20 °C is 4.7 mm²/s.

The study was performed according to internationally accepted test guidelines but was not done under GLP or equivalent QA criteria. This study is classified as reliable with restrictions.
