Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
reduction of the temperature in a rotational test (constant shear rate 1 [1/s]; temperature ramp 2 [°C/min];
stepless increasing of the viscosity with falling temperature - abrupt rise of the viscosity with achievment of the freezing point
GLP compliance:
no
Type of method:
other: determination of the freezing point using a MCR rheometer
