Key result

Temp.:

20°C

Value:

ca. 78.17

Temperature of measuring: 20 °C

Calibration constant of the viscometer: 0.9660 mm².s^-2

 

No.	Viscosity	Unit
1	78.00	mm^2.s^-1
2	78.20	mm^2.s^-1
3	78.30	mm^2.s^-1

Standard deviation: 0.15 mm².s^-1

Average kinematic viscosity: 78.17 ± 0.15 mm².s^-1at 20 °C

Conclusions:

Average kinematic viscosity: 78.17 ± 0.15 mm2.s-1 at 20 °C

Description of key information

Average kinematic viscosity: 78.17 ± 0.15 mm2.s-1 at 20 °C (DEZA, 2009)

The same measured value for dynamic viscosity at 20°C was cited in 3 references without details on test procedure. As one of it (Hawley's dictionnary, 1981) is considered as a reliable document according to R7 guidance document, we consider this value as key parameter.

Key value for chemical safety assessment

Viscosity:

78.17 mm²/s (static)

at the temperature of:

20 °C

Additional information

Dynamic viscosity of DEHP is recorded at 58 mPa.s at 25°C (Rippen 2000). We assume this reference as a reliable document and this data is therefore used a supportive value.
