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)
