Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Test guideline
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Test Guideline 114 (Viscosity of Liquids)
Principles of method if other than guideline:
The Brookfield Programmable DV-II+ Viscometer measures fluid viscosity at given shear rates. The principal of operation of the DV-II+ is to drive a spindle (which is immersed in the test fluid) through a calibrated spring. The viscous drag of the fluid against the spindle is measured by the spring deflection. Spring deflection is measured with a rotary transducer.
GLP compliance:
no
Type of method:
rotational viscometer (dynamic)
