viscosity

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Test Guideline 114 (Viscosity of Liquids)

Principles of method if other than guideline:

Dynamic viscosity (Ƞ) of a Newtonian solvent is generally measured by viscosimeters. Rheometers are used to measure the flow behaviour of viscous fluids, including oils.[1] In this study, Ƞ was calculated by using a rotational rheometer which has recorded changes in solvent viscosity with temperature (°C). Ƞ is measured in Pa s or mPa s (cp).
