Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
viscosity
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2012
Reliability:
1 (reliable without restriction)
Qualifier:
no guideline available
Principles of method if other than guideline:
The kinematic viscosity at 25 ⁰C was determined using a capillary viscometer with Cannon-Ubbelodhe viscometer tube #50. Temperature control was provided by a thermostatically-controlled water bath. The dynamic viscosity was then calculated using density data at 25 ⁰C which were obtained using a Mettler DE40 oscillating tube densitometer.

GLP compliance:
no
Type of method:
capillary viscometer (static)
Standard covering the apparatus used:
The accuracy of the viscometer was validated by determining the dynamic viscosity of standard reference oil N2 from Cannon instruments at 25 ⁰C. Using the density data supplied with the standard, the dynamic viscosity was determined to be 2.638 mPa-s, compared to the reference value of 2.628 mPa-s.
