Endpoint:
viscosity
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2017-04-11
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Qualifier:
according to guideline
Guideline:
ISO 3219 (Plastics; polymers/resins in the liquid state or as emulsions or dispersions; determination of viscosity using a rotational viscometer with defined shear rate)
Principles of method if other than guideline:
The viscosity was measured with a rheometer using the measuring system double concentric cylinders in the shear rate interval 10-100 s-1 at 20 and 40°C. The fluid was Newtonian at the measured temperature and shear rate interval.
GLP compliance:
no
Type of method:
rolling ball viscometer (dynamic)
