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
